Abstract

In monkeys performing a pointing movement, reaction times (RTs) had been studied after permanent exclusion or reversible cooling of the internal pallidal segment. The results show a significant diminution of RT in all treated animals. The role of the internal pallidal segment on the preparatory phase of the motor act is emphasized.
