Volman – JNeurosci – Reduced serotonin transporter availability decreases prefrontal control of the amygdala

After a threatening event, the risk of developing social psychopathologies is increased in short-allele (s) carriers of the serotonin trans- porter gene. The amygdala becomes overresponsive to emotional stimuli, an effect that could be driven by local hypersensitivity or by reduced prefrontal regulation. This study distinguishes between these two hypotheses by using dynamic causal modeling […]

Volman – CurrBio – Anterior prefrontal cortex inhibition impairs control over social emotional actions

When dealing with emotional situations, we often need to rapidly override automatic stimulus-response mappings and select an alternative course of action [1], for instance, when trying to manage, rather than avoid, another’s aggres- sive behavior. The anterior prefrontal cortex (aPFC) has been linked to the control of these social emotional behav- iors [2, 3]. We […]

Volman – CerebCortex – Endogenous testosterone modulates prefrontal–amygdala connectivity during social emotional behavior

It is clear that the steroid hormone testosterone plays an important role in the regulation of social emotional behavior, but it remains unknown which neural circuits mediate these hormonal influences in humans. We investigated the modulatory effects of endogenous testosterone on the control of social emotional behavior by applying functional magnetic resonance imaging while healthy […]
