Many rotation-selective neurons are biased by head direction

(A) Example of a CW-rotation-selective cell that is biased by head direction. (Top) Deconvolved DF/F events (ticks) during CW and CCW rotation trials. White background indicates angular positions that were visited during a trial, and gray background indicates angular positions that were not visited. (Middle) Event histogram for the whole session. (Bottom) Polar histograms of events (bin size = 10° and smoothened using moving average over 5 bins). Dashed vertical lines indicate the stationary positions.

(B) Same as (A) for a CCW example cell.

(C) Percentage of CW or CCW cells that are biased by head direction (HD; 1,368 cells, 4 mice, 4 FOVs).

(D) (Top) Average response of all CW cells that are significantly biased by head direction, sorted according to their preferred head direction. (Bottom) Average response of all CW cells.

(E) Same for all CCW cells.
