Brain Responses to Virtual Reality-Induced Hallucinations in Schizophrenia

by The Neurocritic in The Neurocritic

What is it like to experience the frightening auditory and visual hallucinations characteristic of schizophrenia? Yellowlees and Cook (2006) developed a virtual reality program in Second Life based on interviews with schizophrenic patients. The researchers used this as a tool to educate the general public about schizophrenia, in order to increase understanding and reduce stigma. A video sample of the program can be viewed below.As you can see, these hallucinations are straight out of a horror mo........ Read more »

Textmania: a Modern Manifestation of Manic Hypergraphia?

by The Neurocritic in The Neurocritic

Continuing with the theme of reading and writing, a new study reports on the case of a 23 yr old woman with bipolar I disorder whose output of text messages was "1333.33% more" during a manic episode (Emeagwali et al., 2012):The patient reported a dramatic increase in the quantity of both texting and sex-texting (or sexting) in addition to a decrease in quality of the message content. In addition, there was a substantial increase in the number of people with whom the patient engaged in simultane........ Read more »

G r e a t e r / l e t t e r / s p a c i n g / helps reading in dyslexia

by The Neurocritic in The Neurocritic

Simply increasing the spacing between letters improves the reading ability of children with developmental dyslexia, according to a group of Italian and French researchers (Zorzi et al., 2012). Dyslexic children were 20% faster and twice as accurate when reading the altered text. This impressive result was obtained without any prior training whatsoever.The study was based on the phenomenon of crowding, where the recognition of individual letters is impaired by the close proximity of surrounding ........

Compulsion to write caused by seizure, whether at work or at leisure

by The Neurocritic in The Neurocritic

Hypergraphia is a compulsive or overwhelming urge to write, often associated with temporal lobe epilepsy. Influential behavioral neurologist Norman Geschwind included hypergraphia as one of the personality changes that can be observed in persons with temporal lobe epilepsy.An unusual example of hypergraphia was observed by Dr. Mario F. Mendez, who reported the unique case of a 58 year old man who felt utterly compelled to write poetry (Mendez, 2005). The patient reported no previous history of b........ Read more »

Single-blast exposure induces CTE-like neuropathology in wild-type C57BL/6 mice.In a tour de force, a group of 35 Boston-area scientists1 (Goldstein et al., 2012) developed a mouse model of blast-related neurotrauma that resulted in pathological changes similar to chronic traumatic encephalopathy (CTE), a progressive neurodegenerative disease seen most often in athletes with repeated concussions. They also reported post-mortem neuropathological findings from th........ Read more »

Spindle Neurons in Macaques?

by The Neurocritic in The Neurocritic

Spindle neurons, or Von Economo neurons (VENs), are a unique type of large, bipolar neuron found primarily in layer Vb in the anterior cingulate cortex and the frontoinsular cortex of humans.1 In 1999, Nimchinsky and colleagues discovered that among the 28 nonhuman primate species they examined, only great apes had VENs [see Spindle Neurons: The Next New Thing?].Spindle neurons are also seen in humpback, fin, sperm, and killer whales (Hof & Van der Gucht, 2007), elephants (Hakeem et al., 2........

Neurophysiological Explanation for the Perception of Poltergeists

by The Neurocritic in The Neurocritic

Poltergeist (1982) - IMDb 1 Poltergeists are defined as paranormal, mischievous ghostly presences that appear to a select group of people. As paranormal entities, they are beyond investigation by rational scientific means. Or are they? Odd sensations, visions, felt presences, out-of-body experiences, etc. have all been explained by unusual brain activity. Hence, neuroscientists should consider that poltergeists exist in the mind of the perceiver, not as a physical reality in the external world.A........ Read more »

Magic Buttons, Silver Linings, and Two-Edged Swords

by The Neurocritic in The Neurocritic

The Subjective Ups and Downs of Mood DisordersThe last post, Suffering for art is still suffering, took a critical look at studies claiming that individuals with bipolar disorder are more creative.1 And instead of romanticizing the tortured bipolar artist, it considered the toll the disorder can take on those who live with it (and the people around them).Some readers might have objected to the overly pessimistic tone of that post, prompting them to say things like, "It was a very negative post ........

Critical Theory in Neurocinematics: Gaspar Noe's 'Irreversible' as Neural Network Reconfiguration

Cinematic enfant terrible Gaspar Noé has been shocking audiences with his artistic films of graphic violence for over 20 years. In IMDb he is quoted as saying:"There is no line between art and pornography. You can make art of anything. You can make an experimental movie with that candle or with this tape recorder. You can make a piece of art with a cat drinking milk. You can make a piece of art with people having sex. There is no line. Anything that is shot or reproduced in an unusual way i........

Does the Human Dorsal Stream Really Process Elongated Vegetables?

What do zucchini and hammers have in common? Both might be processed by the dorsal stream.The primate visual system is divided into ventral ("what") and dorsal ("where") visual streams that are specialized for object recognition and spatial localization, respectively (Mishkin et al., 1983; Haxby et al., 1991).Goodale and Milner (1992) conceptualized the two pathways as "vision for perception" and "vision for action":We propose that the ventral stream of projections from the striate cortex to t........

Relativity, by M.C. Escher.The artwork of M.C. Escher is famous for its visual trickery. The human visual system tries to project the two dimensional image onto a three dimensional scene, but the perspective is contradictory: it cannot exist in the real world.

Deep Brain Stimulation for Bipolar Depression

The Melancholia of Kirsten Dunst and Lars von Trier“Gray wool, clinging to my legs, it's heavy to carry along” The disastrous wedding reception of the severely depressed Justine precedes the end of the world, depicted as a highly stylized and artistic event feared by some but welcomed by others. Kirsten Dunst plays the role of von Trier's own melancholia, which was the inspiration for his film. The image above occurred out of context, at the very beginning, during the bombastic Wagner........ Read more »
