According to wikipedia, “Jean Philippe Arthur Dubuffet (July 31, 1901 – May 12, 1985) was one of the most famous French painters and sculptors of the second half of the 20th century.” “He coined the term Art Brut (meaning “raw art,” often times referred to as ‘outsider art’) for art produced by non-professionals working outside [...]

I have a little boy who loves to run and jump and scream and shout – a lot. And by this, I mean running – at full speed and smashing his head into my gut, jumping – off the couch onto my head, screaming – spontaneous curses and R-rated body parts [...]
A look inside brains that carry (my) genetic risk for autism

The A-to-T SNP rs7794745 in the CNTNAP2 gene was found to be associated with increased risk of autism (see Arking et al., 2008). Specifically, the TT genotype, found in about 15% of individuals, increases these folks’ risk by about 1.2-1.7-fold. Sure enough, when I checked my 23andMe profile, I found that I’m one [...]

If you’re a coffee drinker, you may have noticed the new super-sized portions available at Starbucks. On this note, it may be worth noting that caffeine is a potent psychoactive substance of which – too much – can turn your buzz into a full-blown panic disorder. The Diagnostic and Statistical Manual for psychiatry outlines a [...]

If you have a minute, check out this “Autism Sensory Overload Simulation” video to get a feel for the perceptual difficulties experienced by people with autism spectrum disorders. A recent article, “Critical Period Plasticity Is Disrupted in the Barrel Cortex of Fmr1 Knockout Mice” [doi: 10.1016/j.neuron.2010.01.024] provides some clues to the [...]

For a great many reasons, research on mental illness is focused on the frontal cortex. Its just a small part of the brain, and certainly, many things can go wrong in other places during brain/cognitive development, but, it remains a robust finding, that when the frontal cortex is not working well, individuals have [...]

One of the complexities in beginning to understand how genetic variation relates to cognitive function and behavior is that – unfortunately – there is no gene for “personality”, “anxiety”, “memory” or any other type of “this” or “that” trait. Most genes are expressed rather broadly across the entire brain’s cortical layers and subcortical systems. So, [...]

Coping with fear and anxiety is difficult. At times when one’s life, livelihood or loved one’s are threatened, we naturally hightenen our senses and allocate our emotional and physical resources for conflict. At times, when all is well, and resources, relationships and relaxation time are plentiful, we should unwind and and [...]

In their forecast “The World in 2010” special issue, the Economist points to “The looming crisis in human genetics” wherein scientists will reluctantly acknowledge that, even with super-cheap genome sequencing tools, we may not soon understand how genetic variation contributes to complex illness. The argument is a valid one to be sure, but [...]
Reciprocal genetics of autism vs. schizophrenia

The recent paper, “Comparative genomics of autism and schizophrenia” by Bernard Crespi and colleagues provides a very exciting take on how genetic data can be mined to understand cognitive development and mental illness. Looking at genetic association data for autism and schizophrenia, the authors point out that 4 loci are associated with both schizophrenia and [...]

The human brain is renown for its complexity. Indeed, while we often marvel at the mature brain in its splendid form and capability, its even more staggering to consider how to build such a powerful computing machine. Admittedly, mother nature has been working on this for a long time – perhaps since the first neuronal [...]

A recent GWAS study identified the 3′ region of the liver- (not brain) expressed PECR gene (rs7590720(G) and rs1344694(T)) on chromosome 2 as a risk factor for alcohol dependency. These results, as reported by Treutlein et al., in “Genome-wide Association Study of Alcohol Dependence” were based on a population of 487 [...]

One of the difficult aspects of understanding mental illness, is separating the real causes of the illness from what might be secondary or tertiary consequences of having the illness. If you think about a car whose engine is not running normally, there may be many observable things going wrong [...]

File this story under “the more you know, the more you don’t know” or simply under “WTF!“ The new paper, “Microduplications of 16p11.2 are associated with schizophrenia” [doi:10.1038/ng.474] reveals that a short stretch of DNA on chromosome 16p11.2 is – very rarely – duplicated and – more rarely – deleted.

In previous posts, we have explored some of the basic molecular (de-repression of chromatin structure) and cellular (excess synaptogenesis) consequences of mutations in the MeCP2 gene – a.k.a the gene whose loss of function gives rise to Rett syndrome. One of the more difficult aspects of understanding how a mutation in a lowly [...]
