[Cooperative forms of activity of the granular and Purkinje cells in the frog cerebellar cortex].

The method of multimicroelectrode recording of impulse activity from 2 or more neurons with subsequent statistical analysis was used to study spatial and time characteristics of functional relations between granular and Purkinje cells in the frog cerebellar cortex. It was found that under the influence of both mono- and polymodal afferent stimulation the excited granular and Purkinje cells organize themselves into cooperating groups, elementary ensembles 200-300 and 300-400 micronm in size, respectively. Elementary ensembles of these cells are considered as parts of functional blocks which provide information processing in the frog cerebellar cortex. Some of their properties are studied related to the cooperative principle of their organization and activity.
