Fig. 2: FOF neurons encode the rat’s upcoming choice.

a Coordinates used for FOF recordings (+2 AP; ± 1.3 ML). b Average firing rates for three example FOF cells aligned to stimulus onset (left) and movement (right). Activity is conditioned on right (green) vs. left (blue) side choice, as well as hits (solid lines) vs. errors (dashed lines). Shaded regions represent s.e.m. c Side-selectivity at each time point relative to movement for all active cells (left; firing rate > 1 Hz) and for the subset of these cells that meet the spike count pre-movement side-selectivity criterion (right; 2-tailed t test p < 0.05). AUC is computed on spike rates for right versus left choices. Plots are sorted by latency to 200 ms (8 consecutive time bins) of significant AUC values relative to a distribution created by permuting choice labels across trials (2-tailed permutation test, 250 permutations, p < 0.05). d Average activity of all pre-movement side-selective cells conditioned on final state duration and cells' side preferences. Grand-average firing rate at stimulus onset (11.6 Hz) is written in brackets. Source data are provided as a Source Data file.
