Cerebellar lesion effects on vocalization of the squirrel monkey

High-frequency coagulations were made in the cerebellar nuclei of 3 adult squirrel monkeys to test their role in the production of vocalization. Complete bilateral destruction of all 3 nuclei in one animal or destruction of their rostral or caudal halves in the other two had no effect on the acoustic structure of electrically elicited species-specific calls.
