Image via Wikipedia This past friday, I attended my first meditation session at my new yoga school.  I love this school and hope – someday – to make it through the full Ashtanga series and other sequences the instructors do.  In the meantime, I found myself sitting on my folded up blanket, letting my mind [...]

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 [...]

Image via Wikipedia 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 [...]

e. e. cummings via last.fm ***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 [...]

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, [...]

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 [...]

Image via Wikipedia In his book, The Beak of the Finch, Jonathan Weiner describes the great diversity of finches on the Galapagos Islands – so much diversity – that Darwin himself initially thought the finch variants to be completely different birds (wrens, mockingbirds, blackbirds and “gross-bills”).  It turns out that one of the pivotal events [...]

*** PODCAST accompanies this post *** Nowadays, it seems that genomics is spreading beyond the rarefied realm of science and academia into the general, consumer-based popular culture.  Quelle surprise!?  Yes, the era of the personal genome is close at hand, even as present technology  provides – directly to the general consumer public – a  genome-wide [...]

Image by bethd821 via Flickr Whether you are a carpenter, plumber, mechanic, electrician, surgeon or chef, your livelihood depends on a set of sturdy, reliable, well-honed, precision tools.  Similarly, neuroscientists depend on their electrodes, brain scanners, microscopes and more recently their genome sequencers.  This is because they are not just trying to dissect the brain [...]

Image by quapan via Flickr Amidst a steady flow of upbeat research news in the behavioral-genetics literature, there are many inconvenient, uncomfortable, party-pooping sentiments that are more often left unspoken.  I mean, its a big jump – from gene to behavior – and just too easy to spoil the mood by reminding your colleagues that, [...]

Image via Wikipedia Amidst the steady stream of basic imaging and genetic science that pours forth into the literature each day (or in response to Eric Kandel‘s latest update on the state of brain science and mental health), how could anyone remain glum?  In Hamlet, the King asks, “How is it that the clouds still [...]

Image by ibiscus27 via Flickr One of the difficulties in understanding mental illness is that so many aspects of mental life can go awry – and its a challenge to understand what abnormalities are directly linked to causes and what abnormalities might be consequences or later ripples in a chain reaction of neural breakdown.  Ideally, [...]

Image via Wikipedia One of the mental functions many of us take for granted is memory – that is – until we’re at the grocery store.  If you’re like me, you dart out of the house confident that you don’t need a list since you’re just going to “pick up a few things” – only [...]

Image by John Carleton via Flickr I’ve heard of mind reading – yes, some folks have actually figured out (here, here, here) how to decode the fMRI signal to literally know what you’re thinking – but am now beginning to wonder where it all ends. In their new paper, “Transcription MRI: A New View of [...]

Image by -kÇ- via Flickr Session 4 of our discussion group, “When Basic Neuroscience Meets Psych Rehab” will meet on Sept 25. This session will cover the topic of ‘affect labeling’ which is one strategy for managing one’s emotions. Did you know there are 3,000+ words you can choose from to describe your feelings ? [...]

Image via Wikipedia James Schummers, Hongbo Yu and Mriganka Sur present their measurements of Ca++ dynamics in response to visual stimuli in the awake ferret and reveal highly refined patterns of astrocyte activity in their paper, “Tuned Responses of Astrocytes and Their Influence on Hemodynamic Signals in the Visual Cortex” (DOI: 10.1126/science.1156120). The genetic regulation [...]

Image via Wikipedia OK, the title of this post is fanciful – even for the blogosphere – but the recent open access paper, “Using fMRI Brain Activation to Identify Cognitive States Associated with Perception of Tools and Dwellings” by Shinkareva and team (DOI) is pretty darn amazing. The authors ask subjects to view pictures of [...]

Image via Wikipedia Twin studies are oft used to gauge the role of the genome in behavioral science. A recent report, “Nature versus Nurture in Ventral Visual Cortex: A Functional Magnetic Resonance Imaging Study of Twins” by Polk et al., (DOI) shows that brain activity during early stages of visual processing is more similar in [...]

Image via Wikipedia Brain images with red and yellow splotches of activity are now ubiquitous in the psychology literature and well on their way, via neuromarketing, to bamboozling consumers everywhere (eg. this splotch shows that 2/3 people really do prefer Pepsi !). When inappropriately used, fMRI methods can devolve quickly into a high-tech form of [...]
