Figure 8.

Example of best-fit velocity model (Vel) to the spatiotemporal vestibular responses of a single-peaked Purkinje cell. A, Direction-time color plot illustrating how direction tuning evolves over the time course of the response (spatial and temporal resolution: 45° and 100 ms, respectively). B, Model fits (left) and corresponding response residuals (right): model Acc, r² = 0.4; model Vel, r² = 0.77; model AccVel, r² = 0.775, w_a = 0.08, w_v = 0.92), model AccVelPos, r² = 0.78, w_p = 0.1). C, Response PSTHs for eight directions in the horizontal plane together with superimposed curve-fitting lines for each model: Acc (black), Vel (red), AccVel (green).
