Evidence of frontotemporal structural hypoconnectivity in social anxiety disorder: A quantitative fiber tractography study.

abstract：:One of the functions of emotional vocalizations is the regulation of social relationships like those between adults and children. Listening to infant vocalizations is known to engage amygdala as well as anterior and posterior cingulate cortices. But, the functional relationships between these structures still need fur...
