psychology and Art


In 19th century, Sigmund Freud, Austrian psychologist, developed such brilliant, revolutionary theories that made a huge impact both on science and art. Psychoanalysis was a great evolution in psychological society as in the world of art. Here I just skim through some very brief aspects of literature involved with psychology especially Freud's view points. There has been always a big distance between the world of art and psychology, particularly when we tend to imprison psychology by categorizing it merely as an objective science. However many psychologists do not agree with such description and try to broaden the psychological domain. As Dr. Lukman aptly introduced a psychologist as "a REAL doctor", it is essentially suggested to look beyond the limitations of theories and understand the individual diversities. I believe it is true for it includes lots of complexity and a very special set of skills to find the right way out immense cul-de-sacs and scientific prejudice. By defining the unconscious and conscious levels of mind and different aspects of an individual’s personality, the effect and work of the psyche in forming a character was the center of attention for both scientists and artists especially writers and painters.Psychoanalytic Criticism is one of the prominent respects in dramatic arts based on very theories of the Austrian psychologist. It is of note that many of Freud’s hypotheses were applicable both in ancient Greek mythology and drama in such a precise way that raised a huge interest among the great literary authors and critics. For instance the term Oedipus complex is originally taken from a Greek myth who was the protagonist of the famous Greek trilogy, “The house of Thebes”.
(Do bear in mind that the terms art, psychology and literature are combined in every single part of our everyday life such as Television, cinema, stories, novels, colors, streets, stores, people’s character, etc.)
Soon after Carl Gustav Yung, another or more specifically to say the second literary psychologist who was one of Freud’s student, introduced more specific theories on consciousness that fascinated the world of literature as well as in psychology. The complexity of human nature, internal forces affecting the personality and the tendencies towards archetypal forms and symbols were so tactfully classified and scientifically identified in their eminent works. Archetypal or Myth Criticism is one of the main aspects of literary criticism which analyzes and evaluates a literary works through the abstract meanings and archetypal symbols in human psyche. There are many other links that connect art and psychology that I will resume to point them out in further entries. Many other literary terms were evolved and sprung out of the latter ones.

Oedipus the King

Who was Oedipus?

Summary of OEDIPUS


The story of Oedipus the King was told in the play by Sophocles written about 430 B.C. and performed in Athens. Oedipus at Coloneus, the story about Oedipus' old age, was first performed in 402 B.C.
The Delphic oracle prophesied to Laius, the king of Thebes, that he would be killed by a son and that his son would marry his mother. Shocked by such a prophesy, the king and queen decided to kill their first-born son and gave him to a shepherd to be exposed to nature on a mountain and die. The infant's feet were pierced and tied together, and taken by the shepherd. However, the shepherd took pity on the child and took him to Corinth where he was adopted by King Polybus and his childless queen.
When he was grown, Oedipus heard by chance that he was not Polybus's son, and he went to Delphi to learn if it was true. The oracle did not answer his question, but prophesied that he would kill his father and marry his mother. Thinking the prophecy referred to his foster parents, he decided not to return to Corinth. Leaving Delphi, he came upon a man at a crossroads with four attendants who tried to force him from his path. The man, none other than King Laius, prodded him with his stick and Oedipus, arrogant and quick to anger, slew him and three of the attendants. The fourth escaped to report the king's death to the Thebans. The incident was not further investigated because Thebes was having such problems with a Sphinx, a monster with the body of a winged lion and the breast and face of a woman. The Sphinx stood on a rock outside the gates and devoured everyone who failed to solve her riddle: "What creature walks on four feet in the morning, on two at noon and on three in the evening?"
Oedipus solved the riddle and the Sphinx hurled herself to her death on the rocks below. [Can you solve the riddle?]
Oedipus was welcomed as a savior and was offered the vacant throne. He became king and married the queen who, unknown to him, was his mother. The ill-fated city of Thebes was again stricken, now by a plague. Oedipus again asked the Delphic oracle what could stop the plague, and was told that the plague would end when the murderer of King Laius was punished. Later, Oedipus learned that he was the murderer. The awful truth was known about his own past and about who the stranger was on the path. Oedipus plucked out his own eyes in self-hate. Oedipus went to Coloneus, a suburb of Athens, where he spent the rest of his life and was taken care of by his daughter, Antigone.

Unusual penetrating brain injuries

The articles below are taken from //scienceblogs.com/neurophilosophy// and I found it so interesting that I decided to put it up here in my blog, I hope you like it.


Via Street Anatomy comes this recent case report from Acta Neurochirurgica, of a man who had a paintbrush stuck into his brain - bristly end first - during a fight, but didn't realize until 6 hours later, when he went to hospital complaining of a headache! Even more remarkably, any brain damage that may have occurred was apparently insufficient to cause any behavioural or cognitive deficits.
Mandat, T. S., et al. (2005). Artistic assault: an unusual penetrating head injury reported as a trivial facial trauma. Acta Neurochir. 147: 331-333.
The authors report a case of penetrating head injury that presented with a deceptively mild complaint. To our knowledge, it is the first report of a paintbrush penetrating the brain. The patient reported being punched in the left eye and presented with a minor headache, swelling around the left orbit, a small cut on the cheek and slightly reduced left eye abduction. After radiological evaluation, a penetrating head injury was diagnosed. Under general anesthesia, through a lateral eyelid incision a 10.5 cm long paintbrush, which had penetrated from the left orbit to the right thalamus, was removed. No post-operative infection was seen at six months follow-up. This brief report serves to highlight that penetrating brain injury can occur without neurological deficit and that a minimally invasive surgical approach was successful in avoiding any complications.
A lot of people seem to share my morbid fascination with this sort of thing: my recent post on prehistoric Inca neurosurgery brought about a dozen inbound links, and an illustrated history of trepanation is one of the most popular posts I've ever written. So, below are some of the more unusual penetrating brain injuries that I stumbled across while performing a quick search for the one above, starting with the least unusual, a self-inflicted nail gun injury.

Testerman, G. M. & Dacks, L. M. (2007). Multiple self-inflicted nail gun head injury. South. Med. J. 100: 608-10. [Summary]
Penetrating brain injury resulting from nail-gun use is a well-characterized entity, one that is increasing in frequency as nail guns become more powerful and more readily available to the public. We present a case and offer management strategies for a 50-year-old male with two intracranial penetrating nail gun injuries. Nail gun brain injuries are commonly intentionally self-inflicted. Suicide should be considered when straight nails cause wounds to the chest, head, or abdomen. The primary preoperative concern is formation of a traumatic pseudoaneurism, which prompts both preoperative and follow-up cerebral angiography. Surgery for combined intracranial and extracranial injury may require the collaborative expertise of colleagues from the fields of ophthalmology, otolaryngology, and oral maxillofacial surgery. A rational management strategy should permit these patients to be discharged with no additional injury.

Yilkudi, M. G., et al. (1985). Penetrating cranial nail injury. An unusual domestic assault: Case report. East Central Afr. J. Surg. 10: 60-62. [PDF]
A rare case of intracranial nail injury caused by domestic violence is presented. The 35-year old female patient was found unconscious with a 12cm nail almost completely buried into her skull. X-ray of the skull showed the nail in the cranial cavity. A burr hole was made and the nail removed. Immediate post-operative period showed a Glasgow coma score of 10/15 and right hemi paresis which improved with time. At six months after injury, her neurological status was normal. Despite the lack of a CT scan in some areas attempt must be made using clinical judgement and performance of burr holes to treat such patients who cannot afford transfer to a standard neurological centre. This report also highlights the fact that penetrating brain injuries of this nature without much neurological deficit and that a minimally invasive surgical approach can be used successfully to manage such cases while avoiding serious postoperative complications.
James, G., et al. (2006). A case of self-inflicted craniocerebral penetrating injury. Emerg. Med. J. 23: e32. [Summary]
A 44 year old man was referred to the accident and emergency department by the psychiatric services, having claimed to have hammered several nails through his skull over a three month period. The patient had a long history of depression, personality disorder, and previous deliberate self-harm. He had remained well throughout this period and had been cleaning the wounds with weak antiseptic on a regular basis. He had concealed the injuries by wearing a hat. Two days prior to admission he had inserted a much larger 12.7 cm (5 inch) masonry nail and had developed left sided weakness and unsteadiness of gait.
Examination showed that the patient remained well with no evidence of infection in the central nervous system. Neurological examination revealed a mild left sided weakness (4/5 Medical Research Council (MRC) scale) affecting both the arm and leg. The patient was fully alert and orientated and conversed normally. Inspection of the scalp revealed a large masonry nail protruding from the scalp with several other healed puncture wounds. Plain skull X-rays revealed a total of ten 5 cm nails and a larger, 12.7 cm masonry nail penetrating the skull. A computed tomography (CT) scan was performed, which despite considerable artefact confirmed that the nails had penetrated the brain substance. The patient was later transferred to the local neurosurgical unit for further management where, after angiography, all the nails were removed under general anaesthetic. He subsequently made an uneventful recovery.

Karabatsou, K., et al. (2005). Self-Inflicted Penetrating Head Injury in a Patient With Manic-Depressive Disorder. Am. J. Forensic Med. Pathol. 26: 174-7. [Summary]
A 32-year-old Caucasian male with a history of repeated self-injury drilled a hole in his skull using a power tool and subsequently introduced intracerebrally a binding wire from a sketchpad. An emergency craniotomy was performed around the site of cranial injury, and the foreign body was carefully extracted. The wire was located partially in the subdural space and partially in the right hemisphere of the brain. The patient made an excellent recovery and was referred to a psychiatrist for further treatment. This is a rare case of unusual and complex repetitive self-destructive behavior without apparent suicidal intent. The pertinent literature is reviewed and the surgical and psychiatric implications of such injuries are discussed.
This one is horrific, and I should warn you that the paper, which is written in Portugese by Brazilian neurosurgeons, contains a very graphic photograph of the patient's external injuries.
de Andrade, G. C., et al. (2004). Penetrating brain injury due to a large asbestos fragment treated by decompressive craniotomy: case report. Arq. Neuropsiquiatr. 62: 1104-1107. [PDF]
We report the case of a 22-year-old man victim of penetrating brain injury due to a 15 x 12 [cm] asbestos fragment and a successfully treatment [sic] via decompressive craniotomy. Unlike gunshot wounds to the head, penetrating brain injury from low energy objects are unusual. Most reported involve cranio-orbitary injuries as well as self inflicted lesions in mentally ill patients. The reported case is noteworthy due to the large dimensions of the foreign body, the treatment via decompressive craniotomy and the good patient functional outcome.
And we can't forget Phineas Gage, the first properly documented - not to mention best known - case of a penetrating brain injury.

Neurophilosophy : Diagnosing Dostoyevsky's epilepsy

Diagnosing Dostoyevsky's epilepsy
Category: Neuroscience Posted on: Jan 25, 2009 10:42 PM
Fyodor Dostoyevsky (1821-1881) is arguably the greatest novelist of all time. He cast a long shadow over world literature, and subsequently influenced many great writers, from Hermann Hesse, Marcel Proust and Franz Kafka, to Ernest Hemingway, Gabriel Garcia Marquez and Jack Kerouac.
Dostoyevsky had a profound insight into the human condition. He was much more than a novelist: he was also a psychologist and a philosopher. In his novels, Dostoyevsky explored subjects such as free will, the existence of God, and good and evil. The characters in his novels are most often portrayed as living in extremely impoverished conditions. They usually suffered with equally impoverished states of mind, and were always placed within the social and political context of life in nineteenth century Russia. Dostoyevsky was, perhaps, the most famous epileptic in history. The condition had a major influence on his philosophy and his conception of life. A recurring theme in his writing, epilepsy is something he analysed in great detail in many of his novels. Some have speculated that the course of the illness was reflected in how his writing changed throughout his life.
In Dostoyevsky, neurologists have a rich source of information about epilepsy. Some of this information is first-hand, in the form of the writer's own descriptions of his seizures and symptoms, as related in his various correspondences. There are also numerous second-hand descriptions of Dostoyevsky's condition, provided by his second wife, physicians who treated him, and friends. And, of course, there are the accounts of epileptic characters in his novels, which one can safely assume are based on his own experiences.
Dostoyevsky's own descriptions of his condition, and those of his relatives and acquaintances, contain descriptions of various types of epileptic seizures. Dostoyevsky himself wrote, in a letter to his brother Mikhail dated 1865, that he had "all sorts of attacks". Consequently, diagnosing Dostoyevsky's epilepsy has proved extremely difficult, and there has been disagreement among neurologists about the nature of his condition; some have diagnosed him with generalized epilepsy, others believe he suffered from temporal lobe epilepsy, and yet others suggest that he may have had a combination of the two.
An early attempt at diagnosing Dostoyevsky's condition was made by Sigmund Freud, who trained as a neurologist, and described epilepsy as "an organic brain disease independent of the psychic constitution". Freud believed that the condition was incompatible with great intellect, because it was "associated with deterioration and retrogression of the mental performance"; "What is generally believed to be epilepsy in men of genius," Freud wrote, "are always straight cases of hysteria". And this is exactly how the psychoanalyst interpreted Dostoyevsky's epilepsy. In an essay entitled Dostoyevsky and Parricide, which was first published in 1928, Freud suggested that the onset of the Dostoyevsky's epilepsy is intimately connected to the death of his father:
Dostoyevsky called himself an epileptic...it is highly probable that this so-called epilepsy was only a symptom of his neurosis and must accordingly be classified as hystero-epilepsy - that is, as severe hysteria. The most probable assumption is that the attacks went back far into his childhood, that their place was taken to begin with by milder symptoms and that they did not assume an epileptic form until after the shattering experience of his eighteenth year - the murder of his father.
Dostoyevsky was the second of seven children. His father, Mikhail Dostoyevsky, was a retired military surgeon who served as a doctor at Moscow's Mariinsky for the Poor. He was also an alcoholic who was prone to violence, and, although there are numerous accounts of the cruelty with which he treated his children, Dostoevsky's personal correspondences suggests that he and his father had a loving relationship. Nevertheless, Freud asserted that the writer hated his father and wished him dead, and that Dostoyevsky's "alleged epilepsy" was a physical manifestation of the guilt he felt when his father died. Thus, according to Freud, Dostoyevsky's epilepsy was psychological, and not physiological, in origin.
Dostoyevsky's father died in 1839, but the circumstances surrounding his death are by no means certain. According to one account, he was murdered by his own serfs, who restrained him during one of his drunken rages and poured vodka down his throat until he drowned. Another account holds that he died of natural causes, and that a neighbour invented the story of his murder so that he might buy the Dostoyevsky estate at a low price. Regardless, neurologists and scholars of the Slavic language and literature are in agreement that Freud's diagnosis of "hystero-epilepsy" was wrong. They cannot, however, agree on exactly when it was that Dostoyevsky's seizures began. Some believe that they began in Dostoyevsky's childhood, with the first seizure taking place in 1831, when Dostoyevsky was 9 years old, while others claim they began in his teens or early adulthood. Dostoyesky himself stated that his seizures began one Easter night during his exile in western Siberia. He had been arrested on April 23rd, 1849, for his involvement with the Petrashevsky circle, a group of liberal intellectuals. After his arrest, Dostoyevsky was subjected to a mock execution, as a form of psychological torture. Subsequently, he was convicted of political offences against the Russian state, and taken to Semipalatinsk prison in Omsk; some researchers have suggested that the trauma of the mock execution is what triggered his epilepsy.
From 1860, Dostoyevsky recorded the dates of his seizures in a notebook; from that time, up to his death some 20 years later, he documented 102 seizures. This provides the researcher with precise information about the frequency of his attacks. In 1869, for example, he noted that, in previous years, he had been experiencing a seizure about once every three weeks, and that one attack was often followed after a short interval by a second one.
Nikolay Strakhov, a philosopher and literary critic, and a friend of Dostoyevsky's, witnessed one of the great writer's seizures in 1863:
[Dostoyevsky]...walked about the room while I sat at the table. He was saying something lofty and joyous; when I encouraged his idea with some comment or other he turned to me with an exalted look, showing that his emotion was at its height. He stopped for a moment, as if seeking words for his thought, and had already opened his mouth. I gazed at him with fixed attention, sensing that he was about to say something unusual, that I would hear a revelation of some kind. Suddenly there came from his open mouth a weird, longdrawn-out and senseless sound, and he fell unconscious on the floor. This time the fit was not a strong one. The effect of his convulsion was that his whole body stretched out and he foamed at the mouth. In half an hour he regained consciousness and I walked home with him.
Like most of the autobiographical accounts, and those written by other acquaintances, this is a description of a generalized convulsive seizure. This type of seizure, known as a tonic-clonic or grand mal seizure, is characterized by abnormal electrical activity in both hemispheres of the brain; this causes a rigid extensor spasm in which all the muscles in the body contract, which is followed immediately by loss of consciousness.
Here, Dostoyevsky's second wife, Anna Grigorievna, describes the first seizure she witnessed; the description is very similar to that of Strakhov:
Fyodor Mikhailovich [Dostoyevsky] was talking with my sister and was very excited; suddenly he became pale, lurched on the divan and began to lean over to my side. I looked with much astonishment at the change in his face; suddenly came a fearful cry, a cry that had nothing human about it - almost a howl and my husband continued to lean over more and more.
According to Dostoyevsky, most of the seizures of this type occurred at night, when he was either alone or with his spouse. But there are other accounts of seizures which occurred during the daytime, in the presence of other people. These attacks were usually preceded by something called an "ecstatic aura", which is a warning of an impending seizure. The aura sometimes consists of odours, lights, or other sensations; at other times it is just a "gut feeling" that one is about to experience a seizure. It is always followed by loss of consciousness, and is characteristic of temporal lobe epilepsy, which is rarer than generalized epilepsy.
In the following passage, Strakhov relates Dostoevsky's own description of the aura:
Fyodor Mikhailovich often told me that before the onset of an attack there were minutes in which he was in rapture. "For several moments," he said, "I would experience such joy as would be inconceivable in ordinary life - such joy that no one else could have any notion of. I would feel the most complete harmony in myself and in the whole world and this feeling was so strong and sweet that for a few seconds of such bliss I would give ten or more years of my life, even my whole life perhaps."
As a result of his fits he would sometimes bruise himself in falling, and his muscles would hurt him from his convulsions. Now and then his face turned red and sometimes splotches appeared. But the most important thing was that he lost his memory and for two or three days he would feel utterly broken. His mental condition was also grievous: he could scarcely overcome his anguish and hypersensitivity. The nature of this anguish, in his own words, was that he felt he was some kind of criminal; it seemed to him that he was weighed upon by mysterious guilt, by a great crime.
The most notable epileptic characters in Dostoyevsky's novels are Prince Myshkin in The Idiot and Smerdyakov in The Brothers Karamazov. Myshkin is almost certainly an autobiographical character, based on Dostoyevsky's own experiences of epilepsy. Through Myshkin, Dostoyevsky provides the most vivid literary accounts of the ecstatic aura, and he also depicts how epileptics are perceived by society. In his fictionalized accounts of his epilepsy, particularly as portrayed through Myshkin, Dostoyevsky emphasises the reactions of those people who witness the seizures. Myshkin is portrayed as a Christ-like figure whose emotions and intellect have been arrested by his illness. He is ostracized by those around him, partly because of his illness (the "idiot disease"). It is by his accounts of epilepsy, and the stigma attached to it, that Dostoyevsky has contributed hugely to the destigmatization of the condition.
At the beginning of The Idiot, we learn that Myshkin is returning by train to Russia after 4 years at a sanatorium in Switzerland, where he was being treated for "some strange nervous malady - a type of epilepsy, with convulsive spasms". Myshkin also tells his fellow train passengers that "They [the Swiss doctors] could not teach me very much on account of my illness". In this passage, Dostoyevsky gives a vivid account of the ecstatic aura preceding one of Myshkin's seizures:
He was thinking, incidentally, that there was a moment or two in his epileptic condition almost before the fit itself (if it occurred in waking hours) when suddenly amid the sadness, spiritual darkness and depression, his brain seemed to catch fire at brief moments...His sensation of being alive and his awareness increased tenfold at those moments which flashed by like lightning. His mind and heart were flooded by a dazzling light. All his agitation, doubts and worries, seemed composed in a twinkling, culminating in a great calm, full of understanding...but these moments, these glimmerings were still but a premonition of that final second (never more than a second) with which the seizure itself began. That second was, of course, unbearable.
This very famous account of an ecstatic aura has helped neurologists to localise the origins of Myshkin's, and hence Dostoyevsky's, epileptic seizures. The emotional content of the aura suggests that this type of seizure was caused by abnormal electrical activity in parts of the temporal lobe; the emotions are associated with activity in structures of the limbic system - specifically, the hippocampus, amygdala and neocortex of the temporal lobe. The Idiot was written in 1867-68, when Dostoyevsky was having emotional and financial difficulties. With his wife, he set off for Europe, travelling from one city to the next, to avoid his creditors and to seek treatment for his epilepsy. This was a period during which Dostoyevsky experienced a number of severe seizures, perhaps as a result of the psychological burden of his circumstances.
The above account of Myshkin's aura is something akin to a transcendental experience. Indeed, temporal lobe epilepsy is associated with transcendental experiences and hyper-religiosity. For example, the emperor Constantine is believed to have suffered from temporal lobe epilepsy; it is said that, before the Battle of Milvian Bridge in A. D. 312, Constantine saw a vision of the cross emblazoned in the sky, with the words In hoc signo vinces ("In this sign you will win"), and, after winning the battle, made Christianity the official religion of the Roman Empire. Dostoyevsky was deeply religious, and this religiosity may well have been a result of his epilepsy. On Easter night, during his exile in Siberia, Dostoyevsky was visited by an old friend, to whom he described the almost prophetic vision he had experienced during the aura preceding one of his attacks:
The air was filled with a big noise and I tried to move. I felt the heaven was going down upon the earth, and that it had engulfed me. I have really touched God. He came into me myself; yes, God exists, I cried, You all, healthy people, have no idea what joy that joy is which we epileptics experience the second before a seizure. Mahomet, in his Koran, said he had seen Paradise and had gone into it. All these stupid clever men are quite sure that he was a liar and a charlatan. But no, he did not lie, he really had been in Paradise during an attack of epilepsy; he was a victim of this disease as I am. I do not know whether this joy lasts for seconds or hours or months, but believe me, I would not exchange it for all the delights of this world.
Several other lines of evidence point to temporal lobe epilepsy. Firstly, two notations by Dostoyevksy describe a speech disorder following some of his fits: one entry in his diary reads "I was a long time unable to speak"; another reads "When writing I still made mistakes with the words". These accounts of impaired speech following a seizure (a symptom known as postictal dysphasia) would also suggest that the origin of Dostoyevksy's seizures lay in the medial region of the left temporal lobe, because activity in this region of the brain would likely affect Broca's area, the sppech centre in the left temporal lobe. Also, in 1880, while he was writing his last novel, Dostoyevsky's 3 year-old son Alyosha, died of epilepsy. Of all the known types of epilelpsy, only three are known to have a genetic component, and temporal lobe epilepsy is one of them.
Dostoyevsky's last novel, The Brothers Karamazov, which was completed in late 1880, just a few months before the writer's death, provides a possible explanation for the different types of seizures described in various accounts of the writer's epilepsy. In the novel, the epileptic character is Smerdyakov, the illegitimate orphan son of Karamazov Snr., the product of a rape, who was "conceived in a fetid passage". In what could be an allusion to Dostoyevsky's own circumstances, we learn that Smerdyakov's seizures apparently started one week after he is slapped about the face by Grygory, one of the familie's servants. Subsequently, he has seizures of varying severity about once a month. Later on, Smerdyakov takes revenge upon those who rejected him by murdering his father and putting his older brother in the frame. He then stages a simulated seizure to provide himself with an alibi. After murdering his father, Smerdyakov confesses to his brother Ivan:
"You had gone away, then I fell into the cellar." "In a fit, or in a sham one?" asked Ivan "A sham one, naturally. I shammed it all. I went quietly down the steps to the very bottom and lay down, and as I lay down I gave a scream, and struggle, 'til they carried me out to the room adjacent to old Karamazov's." Ivan learns too late that he has underestimated Smerdyakov: "You are not a fool..."
Thus, it transpires that Smerdyakov had real epileptic seizures, but also acted out sham non-epileptic seizures. Evidently, Dostoyevsky was well aware of the advantages of the ability to stage sham seizures, and may have done so himself on some occasions, to avoid over-emotional situations with his spouses or encounters with those he owed money to.
Dostoyevsky's descriptions of the condition were in line with contemporary neurology, and they remain accurate to this day. In The Idiot, he explains, through Myshkin, that the ecstatic aura is "characterized by a fulguration of the consciousness, and by a supreme exaltation of emotional subjectivity", and a note in his diary, dated September 7th, 1880, reads: "This morning at 8.45, interruption of my thoughts, transported into other years, dreams, dreamy states, dreaminess...guilt." This is very similar to the description of the aura provided by the eminent British neurologist John Hughlings-Jackson (1835-1911), who called it the "dreamy state". Towards the end of Dostoyevsky's life, Hughlings-Jackson had accurately characterized medial temporal lobe epilepsy, and, during post-mortem examinations, correlated it with lesions in the medial temporal lobe. From the first-hand accounts provided by his epileptic patients, Hughlings-Jackson described the aura as a state of "over-consciousness," which had "crude sensations" of smell and taste and a heightened intellectual state associated with it:
The so-called "intellectual aura" (I call it the "dreamy state") is a striking symptom. This is a very elaborate or voluminous mental state. One kind of it is a "reminiscence"; a feeling that many people have had when apparently in good health.
Dostoyevsky's vivid descriptions of the aura have therefore led many researchers to diagnose him with temporal lobe epilepsy. But some believe he suffered from generalized epilepsy with secondary ecstatic epilepsy. Dostoyevsky may have suffered mild epileptic attacks in his early years; later on, his condition may have been exacerbated by certain events in his life - exile, mock execution, the burden of debt, and even his compulsive gambling - so that his attacks were punctuated every now and then with more severe seizures that were preceded by auras. Another possibility is that Dostoyevsky experienced generalized seizures that were triggered by focal activity in the medial temporal lobe. Because of his epilepsy, Dostoyevsky was, to borrow the title of his second novel, a "double man"; a rational, exalted being on the one hand, and, because of his illness, a mystical and base creature on the other. It seems that as his life progressed, and his epilepsy became more severe, the latter persona prevailed, as evidenced by the increasingly mystical nature of the work produced later in his life.
