Spike activity related to the problem of alternative choice of behavioral actions was recorded in the putamen of the monkey brain. The patterns of low and high activities were identified. Each neuron during different behaviour actions could generate any kind of patterns. The differences between neuronal compositions with patterns of high activity, at the left and right direction of the task, were obtained during decision making about the movement direction, and also at the end of the movement. Distinctions between neuronal compositions with patterns of low activity at this time, on the contrary, diminished. The neuronal compositions with patterns of low activity were much more before the conditioned signal, when the animal did not yet know the task, and at the end of the program when the problem was already solved. The data obtained show that the putamen units control different directions of actions by a multilevel address coding, mainly through reorganizing the neuronal compositions with patterns of different level activity.
