Putamen neuron spike activity associated with motor and nonmotor functions was studied in monkeys trained to behavioral programs consisting of a series of sequential actions. In general, each putamen neuron was activated during particular behavior fragments. The association of each individual neostriatal neuron with particular behavioral fragments was not(More)
Two types of neuron spike activity were detected in the striatum (putamen) of monkeys: patterns with low and high activity. Low-activity patterns were no more than twice the level of baseline activity, while high-activity patterns had larger factors. An individual neuron could generate different patterns during different actions. On performance of tasks(More)
Significant differences were found in collective unit activity of 6 neostriatum neurons associated with performance of either left- or right-sided task by monkeys: at the moment of decision-making regarding the direction of the movement, and after its completion, irrespective of correctness of the choice. The differences at the moment of the programme(More)
Spike activity in monkey striatum (putamen) neurons was recorded during the performance of a complex multistep operant task. Tonic responses propagating beyond a single action were recorded, along with phasic responses seen within a given action. The tonic type of response was recorded in 132 of 148 cells. Only 11 of these neurons showed exclusively this(More)
Experiments with simultaneous recording of six neostriatum neurons showed that the neurons of this structure are involved in the organization of all stages of behavior. A defined combination of neuronal activity corresponded to each action of the animal. The responses of individual neostriatal neurons were not entirely determined by the action being carried(More)
It has been shown that paradoxical sleep (PS) total time (TT) in euthermia phase of hibernation cycle (winter sleep) can be compared with its mean values in euthermia season. Ultradian fluctuations of PS episodes duration, TT and phase number as well as bradycardia microintervals are revealed in euthermia phase dynamics. Amplitude of these fluctuations(More)
Single unit activity was recorded in monkeys in three putamen zones learned a bimanual operant activity during performance of the task of alternative spatial choice. The neuronal reactions were specially analyzed by the criteria as follows: a) differentiation of the side of reward (differentiating--non-differentiating reactions); b) character of reaction by(More)
