Figure 5. A cerebellar circuit model that reproduces the features of trial-over-trial depression of simple-spike firing rate and trial-over-trial learning in eye velocity.
The schematic on the left shows the cerebellar circuit on which our model was based. Abbreviations are: PC, Purkinje cell; DCN, deep cerebellar nucleus; IO, inferior olive. (A and D) Trial-over-trial change in simple-spike firing rate and eye velocity in the model, after Figure 4A,D. (B, C, E and F) Predictions for the firing rate responses in the first, second, and third trials in trios with different combinations of CS responses, after the same panels in Figure 4. The x-axes show time with respect to the onset of the instruction.
