The available experimental data do not provide a sufficiently complete picture of the neuronal activity connected with some action of the animal, as they have been obtained under different experimental protocols and as a result of study of different cells. The present work was aimed at studying activity of the same neuron group at different moments of(More)
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)
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)
The structure of the mixed crystal [K1-x(NH4)x]3H(SO4)2 as obtained from single-crystal neutron diffraction is compared with the previously reported room-temperature neutron structure of crystalline K3H(SO4)2. The two structures are very similar, as indicated by the high value of their isostructurality index (94.8%). It was found that the replacement of(More)
Neuron spike activity was recorded in the putamen of monkeys trained to perform bimanual operant behavior consisting of nine separate steps. Neuronal reactions were present at all steps: in 52–62% of cases during movement, and in 27–36% of cases during responses to the trigger and conditioned signals and as the monkeys decided which was the working hand.(More)
Polymodality is a specific feature of the striatum. The monkey caudate nucleus and putamen have been shown to contain neurons responsive to sensory stimuli [1, 2], reward expectation and receiving [3, 4], memory and attention processes [5, 6], planning and implementing movements [7, 8], etc. As all these data came from very diverse experiments performed by(More)
