The perception of facial emotions - cues from the left amygdaloid complex

摘要

The history and the behavioral profile of 2 patients with brain abnormalities in the region of the left amygdaloidal complex might suggest that the dysfunction of the neural pathways related to the left amygdala has to occur at an early developmental stage to result in impaired emotional judgments of facial expressions. This is in line with the hypothesis that emotional information processing is based on a distributed neural network which, during ontogenesis, gradually expands from the amygdala and the amygdaloidal complex to further components of the limbic system.
