Complete unilateral section of the pyramidal tract at the medullary level in Macaca mulatta

Abstract

A short movie was shown to illustrate the motor deficits in hand usage which result in the adult monkey after complete unilateral section of the medullary pyramid at the level of the trapezoid body. The animal (68-70) was one of 8 in which unilateral or bilateral pyramidal section was undertaken for the primary purpose of studying the effects of pyramidal tract section on movements elicited by electrical stimulation of the rolandic region of the cerebral cortex. The results obtained in these 8 animals formed the subject of the J. Hughlings Jackson Memorial Lecture given at the Montreal Neurological Institute on May 11, 1971.
