AHV can be decoded from neural activity in the RSC

(A) Example trial sequence showing a mouse being rotated in the CW or CCW direction. The periods when the mouse is stationary are removed. Traces show the actual rotation direction and that predicted by the LNP model. For decoding, all neurons in a FOV were used regardless of whether they were rotation selective or not.

(B) Same trial sequence as shown in (A) but now showing the angular head velocity (AHV).

(C) Scatterplot showing the actual AHV of a trial and that predicted by the LNP model. All trials of all mice are included (16 sessions, 1,102 trials, 10 mice). The size of a bubble indicates the number of trials. The number of neurons used for decoding was 308 ± 15 (average ± SEM) per session.

(D) The percentage of trials (average ± SEM) correctly decoded by the LNP model.

(E) The decoding error (average ± SEM) using the LNP model as a function of actual rotation velocity.

(F) The decoding error as a function of the number of random neurons used for decoding.
