Abstract：
:In 22 squirrel monkeys (Saimiri sciureus) vocalization-eliciting electrodes were implanted into the amygdala and along the trajectory of the stria terminalis. Then, lesions were placed in the stria terminalis, its bed nucleus, the ventral amygdalofugal pathway and several di- and mesencephalic structures in order to find out the pathways along which the amygdala exerts its vocalization-controlling influence. It was found that different call types are controlled by different pathways. Purring and chattering calls, which express a self-confident, challenging attitude and an attempt to recruit fellow-combatants in intra-specific mobbing, respectively, are controlled via the stria terminalis; alarm peep and groaning calls, in contrast, which indicate flight motivation and resentment, respectively, are triggered via the ventral amygdalofugal fibre bundle. Both pathways traverse the dorsolateral and dorsomedial hypothalamus, respectively, and unite in the periaqueductal grey of the midbrain.
