Abstract :
At the IJCNN´93 in Nagoya we 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; and (4) SS cross-correlation between twin cells is zero, thus contradicting a naive prediction of several cerebellar learning theories
