Born in West Virginia in 1980, The Neurocritic embarked upon a roadtrip across America at the age of thirteen with his mother. She abandoned him when they reached San Francisco and The Neurocritic descended into a spiral of drug abuse and prostitution. At fifteen, The Neurocritic's psychiatrist encouraged him to start writing as a form of therapy.
Brain activation during challenges to political vs. non-political beliefs (Figure modified from Kaplan et al., 2016).
Lately I've been despairing about the state of America.
I'm not sure how denying access to affordable health care, opposing scientific facts like global warming and the benefits of vaccines, alienating our allies, banning Muslims, building a wall, endorsing torture, and

The neural machinery that forms new memories is fragile and vulnerable to insults arising from brain injuries, cerebral anoxia, and neurodegenerative diseases such as Alzheimer's. Unlike language, which shows a great deal of plasticity after strokes and other injuries, episodic memory – memory for autobiographical events and contextual details of past experiences – doesn't recover after

Airline travel during the holidays is one big headache. But for some people, “airplane headache” is a truly painful experience. The headache occurs during take-off and landing, is unique to plane travel, and is not associated with other conditions. The pain is severe, with a jabbing or stabbing quality, and located on one side of the head (usually around the eye sockets or forehead).

Franz Joseph Gall (1758-1828), a founding father of phrenology
Phrenology was the pseudoscience of identifying a person's character and mental abilities on the basis of skull morphology (“bumps on the head”). The enterprise was based on four assumptions (Gross, 2009):
intellectual abilities and personality traits are differentially developed in each individual
these abilities and traits

Bugs Bunny in Hyde and Hare (1955)Delusional misidentification syndromes have fascinated filmmakers and psychiatrists alike. Afflicted individuals suffer under the false belief that persons or things around them have changed their identities or appearance.

The journal Brain has a new review on the history of converting the electroencephalogram (EEG) into sound (Lutters & Koehler, 2016). The translation of data into sound, known as sonification, has been applied to brain waves since the 1930s. In addition to early scientific and medical applications, sonification of the EEG has been used in the field of experimental music.In 1965, physicist Edmond Dewan and composer Alvin Lucier collaborated on Music for the Solo Performer:Sitting on a cha........

Activity of the medial prefrontal cortex after psycho-spiritual healing (Baldwin et al., 2016).Everything we do and feel and experience changes the brain. Psychotherapy, juggling, taxi driving, poverty, reading, drugs, art, music, anger, love. If it didn't we'd be dead. Why should prayer be any different? The trick is to accurately determine the structural or physiological changes that are unique to a specific activity. And when assessing the effectiveness of clinical interventions, how the chan........ Read more »

Headache, Guillaume DELEBARRE (Guigui-Lille)A recent neuroessay in the New York Times asked, Can Tylenol Help Heal a Broken Heart?What’s crazy about the pain of a broken heart is that your body perceives it as physical pain.No it does not.

You may have seen headlines such as: Florida Man Woke Up In A Motel Room Speaking Only Swedish. Or: Englishman wakes up speaking Welsh after stroke (“Rare brain disorder left English-speaking Alun Morgan only able to communicate in Welsh”). The first case was likely due to a fugue state, a type of dissociative disorder involving loss of personal identity and aimless wandering (Stengel, 1941). The second seems like an unusual example of bilingual aphasia involving loss of the ability to spea........ Read more »

When you hear the word “apple”, do you picture a Red Delicious apple or a green Granny Smith? Or neither, because you can't conjure up a visual image of an apple (or of anything else, for that matter)? Aphantasia is the inability to generate visual images, which can be a congenital condition or acquired after brain injury (Farah, 1984). The most striking aspect of this variation in mental life is that those of us with imagery assume that everyone else has it, while those without are flabberg........ Read more »

New in the journal journal Cortex: four shocking cases of practicing medicine while exhausted (Dharia & Zeman, 2016). The authors called this newly discovered syndrome “fatigue amnesia.” Why this is is any different from countless other examples of not remembering things you did while exhausted — I do not know. Except amnesia for performing a complex medical procedure is a lot more disturbing than forgetting you did the dishes the night before.Here are the cases in brief:Case 1:&........ Read more »

Our bodily sense of self contributes to our personal feelings of awareness as a conscious being. How we see our bodies and move through space and feel touched by loved ones are integral parts of our identity. What happens when this sense of self breaks down? One form of dissolution is Depersonalization Disorder (DPD).1 Individuals with DPD feel estranged or disconnected from themselves, as if their bodies belong to someone else, and “they” are merely a detached observer. Or the self feel........ Read more »

Who is this, wandering around the crowded street, afraid of everything, trusting no one? “There must be something wrong, somewhere.”But maybe I’m safer since I look disheveled. Who are these people? Where is this place?Did I write that? When did that happen? I don’t remember. I can’t stop writing. I can’t stop walking, either, which is a problem because it’s hard to write and walk at the same time.In the early 1940s, Austrian Psychiatrist Dr. Erwin Stengel wrote a pair of papers........
