Negative BOLD response and serotonin concentration within rostral subgenual portion of the anterior cingulate cortex for long-allele carriers during perceptual processing of emotional tasks

摘要

We investigated the effect of synaptic serotonin concentration on hemodynamic responses. The stimuliparadigm involved the presentation of fearful and threatening facial expressions to a set of 24 subjects whowere either5HTTLPR long- or short-allele carrie
