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 [...]
Genetic road signs for super-size coffee SUV drivers

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 [...]

Oxygen is the key to life. This is because it loves electrons. In the mitochondria of every cell in your body, oxygen (in is atmospheric O2 state) serves as the ultimate electron acceptor and provides the chemical energy that drives the formation of ATP (a form of chemical energy storage that [...]

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 [...]

Everyone has a birthday right. Its the day you (your infant self) popped into the world and started breathing, right? But what about the day “you” were born – that is – “you” in the more philosophical, Jungian, spiritual, social, etc. kind of a way when you became aware of being in some [...]
Semaphorins integrate the sweetness and development of our cortical 6-layer cake

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 [...]

***PODCAST ACCOMPANIES THIS POST***
In his undergraduate writings while a student at Harvard in the early 1900’s E. E. Cummings quipped that, “Japanese poetry is different from Western poetry in the same way as silence is different from a voice”. Isabelle Alfandary explores this theme in Cummings’ poetry in her essay, “Voice [...]

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, [...]
C.H. Waddington provides conceptual framework for shifting influences of genes and environment in the development of mind

Just a pointer to onetime University of Edinburgh Professor C.H. Waddington’s 1972 Gifford Lecture on framing the genes vs. environment debate of human behavior. Although Waddington is famous for his work on population genetics and evolutionary change over time, several of his concepts are experiencing some resurgence in the neuroimaging and psychological development literatures these [...]
Thousands of genes together with thousands of resting-state nodes actually makes the genes-to-cognition problem LESS complex

DON’T tell the grant funding agencies, but, in at least one way, the effort to relate genetic variation to individual differences in cognitive function is a totally intractable waste of money.
Let’s say we ask a population of folks to perform a task – perhaps a word memory task – and then we use neuroimaging to [...]

We are all familiar with the notion that genes are NOT destiny and that the development of an individual’s mind and body occur in a manner that is sensitive to the environment (e.g. children who eat lots of healthy food grow bigger and stronger than those who have little or no access to food). In [...]

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 [...]
Krill-sized genetic risk factors caught with fine NRG1 netting

The neuregulin-1 (NRG1) gene is widely known as one of the most well-replicated genetic risk factors for schizophrenia. Converging evidence shows that it is associated with schizophrenia at the gene expression and mouse model levels which are consistent with its molecular functions in neural development. However, in several recent genome-wide association studies (GWAS), [...]

“A devil, a born devil, on whose nature

Humanely taken, all, all lost, quite lost
And as with age his body uglier grows,
So his mind cankers.”

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 an analysis [...]
