Abnormal functional architecture of amygdala-centered networks in adolescent posttraumatic stress disorder.

abstract：:The literature points to a large distributed brain network involved in the estimation of time. Among these regions, the role of the insular cortex is still poorly understood. At the confluence of emotional, interoceptive, and environmental signals, this brain structure has been proposed to underlie awareness of the pa...
