Example of best-fit acceleration + velocity model (AccVel) 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 = 0.53); model Vel (r² = 0.59); model AccVel (r² = 0.81, w_a = 0.54, w_v = 0.46); model AccVelPos (r² = 0.816, w_p = 0.03). C, Response PSTHs for eight directions in the frontal plane together with superimposed curve-fitting lines for each model: Acc (black), Vel (red), AccVel (green).
