In order to study the role of the striatum in generation of multistage behavior, the spike activity of 148 cells was recorded in the monkey brain putamen. Two kinds of neuron responses were observed. Phasic response involved activity during only one stage of the behavior program, and tonic response involved activity during more than one sequential stage. The tonic responses were recorded in 132 neurons out of 148, 11 neurons responding only as tonic. Other 121 cells show under different conditions both tonic and phasic responses. Beginnings and ends of "tonic" responses as a rule corresponded to the start and completion of the nearest behavioral aim. The obtained data suggest that the neuron activity of striatum is related not only to the control of individual movements but also to the whole structure of behavior.
