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.

Amygdala Vegetariana
by The Neurocritic in The Neurocritic
In Short Cuts, the "vegetarians and vegans are more empathetic" neuroimaging article was mentioned in passing, but I didn't actually blog about it. However, there has been one thing [OK, more than one thing] bothering me about this paper... But first, a quick summary of the Methods which were rather straightforward.Filippi and colleagues (2010) recruited 20 omnivores, 19 vegetarians, and 20 vegans to participate in a study that examined their brain responses to images of human and animal suffer........

There is way too much to blog about these days. I can't decide among these 3 new papers:Sometimes, Categorical Statements about Prefrontal Neurons Are Just Wrong(1) Earl K. Miller (2007) in The Prefrontal Cortex: Categories, Concepts, and Cognitive Control (PDF):There was virtually no category effect across the ITC [inferior temporal cortex] population and no examples of neurons whose activity showed the sharp across-distinction/within-category generalization that is the behavioral signature of ........

Attentional bias and "gaydar"
by The Neurocritic in The Neurocritic
Global or Local? Gay or Eurotrash? Navon figure flanked by two game pieces from Gay or EUROtrash? the ultimate gaydar game!Believe it or not, there's an article in the new journal Frontiers in Cognition1 entitled "Sexual orientation biases attentional control: a possible gaydar mechanism" (Colzato et al., 2010). What is "gaydar"? And why on earth would one think of studying the allocation of attention to global and local visual perceptual features in relation to gaydar? Here's why:Individuals ........

Towards a Focal Consensus in Cognitive Neuroscience: Databases and Meta-Analyses
by The Neurocritic in The Neurocritic
Moving right along with our timely, fast-paced, cutting edge blog coverage from the CNS 2010 Annual Meeting [held last month], the first symposium urged the field to advance beyond the current piecemeal single-study approach to neuroimaging by moving Towards a cumulative science of human brain function.1 Building comprehensive, structured, and searchable databases (Van Essen, 2009) and using meta-analytic tools (Wager et al., 2009) were proposed to be key methods aimed at achieving this goal.........

Motivating a Cumulative Cognitive Neuroscience
by The Neurocritic in The Neurocritic
Why are large-scale structured databases and meta-analyses important to advance the field of human brain mapping? One reason is that individual functional magnetic resonance imaging (fMRI) studies can be notoriously unreliable and underpowered (Bennett & Miller, 2010; Fliessbach et al., 2010; Kriegeskorte et al., 2009; Vul et al., 2009).

Training of Executive Control Functions: Negative Transfer and Far Transfer
by The Neurocritic in The Neurocritic
The Cognitive Neuroscience Society 2010 Annual Meeting was held last week in Montreal, Québec. Unfortunately, many European registrants were unable to attend because of the Eyjafjallajokull volcano. The meeting website has links to the PDFs for 67 of these "Volcano Posters".One of those unable to attend was Dr. Jonas Persson of Stockholm University.

"Sleeping Beauty Paraphilia" and Body Image Disturbance After Brain Injury

Brain injuries caused by strokes, tumors or head trauma can, on occasion, result in Unusual Changes in Sexuality, as discussed in an earlier blog post. A new case report by Bianchi-Demicheli et al. (2010) describes a unique paraphilia1 in a married 34 year old man. The authors called it Sleeping Beauty paraphilia:This [man] felt sexually aroused from seeing sleeping women as well as from taking care of their hands and nails while they were asleep.The patient came to the attention of the authors ........

Professor of Literary Neuroimaging

Voodoo and Type II: Debate between Piotr Winkielman and Matt Lieberman
by The Neurocritic in The Neurocritic
"Voodoo correlations in social neuroscience" was the original title of a paper that first caused a stir in late December 2008, when a manuscript accepted by Perspectives on Psychological Science was made available on the authors' websites. Vul, Harris, Winkielman, and Pashler produced a "bombshell of a paper" that questioned the implausibly high correlations observed in some fMRI studies in the field of Social Neuroscience. Ed Vul et al. surveyed the authors of 54 papers to determine the an........ Read more »

Midsagittal brain image (PALS cortical surface atlas, Van Essen 2005) shows resting state functional connectivity in three cortical networks: (i) dorsal attention system (DAS, blue); (ii) the salience system (light green); and (iii) the default mode network (orange).

Friston is Freudian
by The Neurocritic in The Neurocritic
Professor Karl Friston is one of the most prominent (and prolific) researchers in the field of neuroimaging. His contributions to methodological development in functional magnetic resonance imaging (fMRI) are immense:He invented statistical parametric mapping; SPM is an international standard for analysing imaging data and rests on the general linear model and random field theory (developed with Keith Worsley). In 1994, his group developed voxel-based morphometry. VBM detects differences in n........ Read more »

Depression's Cognitive Downside
by The Neurocritic in The Neurocritic
Author and blogger Jonah Lehrer has a lengthy (and controversial) essay in the Feb. 28 New York Times Magazine on Depression's Upside. The main idea, that depression has cognitive and evolutionary advantages, was largely based on a review paper by Andrews and Thomson (2009). In it, they put forth the analytical rumination hypothesis: depression is an evolved response to complex problems, and focusing on them to the exclusion of everything else is beneficial. Lehrer's piece generated an outpourin........ Read more »

Unusual Headaches

Headache, by Robert Magginetti (Tranquility Base)In the last post we learned about Alice in Wonderland syndrome, a rare phenomenon involving distortions of visual perception and body image, most often caused by migraines.
