Abstract

Level of the unit activity was studied in the monkey putamen during multistage behavior. Two groups of neuron activity patterns were distinguished. The first one involved patterns of low level neuron activity less exceeding the background level than the second one; the other group involved patterns of high level neuron activity exceeding the background level in the second time. These kinds of patterns were behavior-related. Patterns with low level neuron activity were recorded preferentially in relation to the trigger stimuli and reward. Patterns of high level neuron activity were recorded in relation to the decision-making, movements of arms in the left and right directions. Besides, their number rose in relation to the auditory cue reported to right realization of the task. It was established that the number of patterns of high level neuron activity rose in key moments of behavior, while the number of the patterns of low level neuron activity decreased.
