Abstract

1. We studied the physiology of the neuronal projection from the striatum to the external and internal segments of the globus pallidus (GPe and GPi, respectively) in macaque monkeys. The objective of the study was to answer the following specific questions. 1) Which classes of the electrophysiologically identified striate neurons project to GPe and GPi? 2) What kind of information is transferred from the striatum to GPe and GPi during learned movement? 3) What are the physiological actions of striate projection neurons on target neurons in GPe and GPi? 4) What is the spatial pattern of the striatopallidal projections? 2. Sequential arm and orofacial movements were used as behavioral tasks. Visual stimuli triggered a sequence of three flexions-extensions of the elbow joint across the target, and the click of a solenoid valve triggered repetitive licking movements. 3. Striatopallidal projection neurons were electrophysiologically identified by antidromic activation after focal stimulation of either GPe or GPi. Of two classes of striate neurons, tonically active neurons (TANs) with tonic spontaneous discharges (2-8 imp/s) and broad action potentials, and phasically active neurons (PANs) with a very low spontaneous discharge rate (...Continue Reading
