[Electrophysiologic analysis of the functional organization of cortico-cerebellar connections].
The influence of associative (orbital-anterior, parietal) and projective (auditory, sensomotor) cerebral cortex areas stimulation on activity of the Purkinje neurons of cerebellar cortex was studied in adult cats under chloralose-nembutal or nembutal anesthesia. These reactions were compared with the responses to peripheral stimuli. Definite similarity in responses of the Purkinje cells to different cortical (associative, projective) stimuli was found both for types of neurons and their responsiveness. In responses of the Purkinje cells to peripheral stimulation there was no sharp similarity as it was in responses to cortical stimuli. So, in cortical stimulation almost similar number of neurons (above 50%) was excited and in peripheral stimulation the responsiveness of neurons had marked difference: to electrical stimulation of skin there were 44.6%, to auditory 34.2%, to visual 18.8% of neuron responses.
