Title

Climbing Fiber Purkinje Cell Twins Are Found

Abstract

At the IJCNN'93 in Nagoya we have pronounced a challenging goal: to get activity patterns of pairs of Purkinje cells (PC), controlled with the same climbing fiber (CF), - a CF PC Twins problem. Here, for the first time in cerebellar studies, CF PC twins have been identified and studied. Several important features of the CF PC twins activity are demonstrated: (1) High constancy of conduction time of impulses of cells of inferior olives to the targeted PCs, (2) A relatively high failure rate (0.05-0.18) of impulse propagation into terminal branches of CF, (3) A salient difference in complex spikes (CS) - simple spikes (SS) interaction between the PC twins, (4) SS cross-correlation between twin cells is zero, thus contradicting a naive prediction of several cerebellar learning theories.
