Summary
In this study 90 electrode positions, obtained from 13 adult squirrel monkeys, are presented from which vocalizations were reproducibly evoked by electrical brain stimulation. For 49 of these positions the evoked vocalization was classified according to our call catalog. Eleven of the 26 vocalizations listed in our catalog were elicitable by electrical brain stimulation. In addition to vocalization of a single type, vocalization sequences, which were indistinguishable from spontaneously occurring ones, could be elicited from fixed electrode positions. Aggression calls were found predominately in the hypothalamus and amygdala, contact calls in the septum. Among the evoked responses occurring simultaneously with vocalization, the genital response is of greatest interest since it also occurs in a spontaneous context with vocalization; specifically as a component of genital display.
