Description
Summary:The baseline impulse activity of neurons of the central nuclei of the cerebellum was investigated in awake cats under chronic experimental conditions through the use of various methods of statistical analysis. Differences were identified, along with the predominance of irregular impulse streams in the neurons of all the nuclei, in the relationship of individual varieties of the baseline activity of the neurons, both with respect to the pattern of the activity and with respect to the dynamics of the repetition of the interimpulse intervals, as well as with respect to other statistical characteristics of the distribution of the interimpulse intervals in each nucleus. It is hypothesized that the variations in the baseline impulse activity of neurons of individual nuclei are determined by their cytoarchitectonic features and by the varied distinctness of the correlating tonic afferent and cerebellar cortical influences.
