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 Rare mutations that knock-out the function of monoamine oxidase a gene have long been known to give rise to developmental changes that increase the propensity of males to engage in aggressive behavior.  The effects of so-called natural variants – that may slightly reduce or increase the amount of activity of the MAOA [...]

Image by Ginger Me via Flickr As I and many other 23andMe participants begin to confront our genetic innards, we will likely ask whether any of the information is predictive.  Can we expect to read-off our genomic information and say, “I have risk for this, this, and this, and so I’ll change my life to [...]

Image by cibomahto via Flickr A recent paper from Andreas Heinz and colleagues (doi: 10.1038/nn2222) provides more neuroimaging evidence in humans for a a circuit that regulates our responsivity to stimuli that evoke emotional responses.  The basic circuitry involves the amygdala (a place in the brain where emotional memories are registered), the prefrontal cortex (a [...]
