Complex spike firing. A, Raster and average firing plots of the complex spike discharge of a Purkinje cell throughout the adapt epoch. A significant change in complex spike firing compared with baseline is denoted by black and periods of no change by gray. Vertical line is movement onset and the time of the mechanical perturbation is denoted by the gray vertical bar. The bars at the top show the time windows used including the three baseline (B1–B3), premovement (PM), movement (M), and three perturbation windows (P1–P3). B, C, Population averages for the 49 Purkinje cells aligned on either movement onset (MO in B) or perturbation onset (PO in C).
