Choice Encoding
(A) (Top) Example raster plot of a vS1 unit. Trials are grouped according to rat’s choice; only correct trials are included. Colored boxes demonstrate the parts of SGM that are included in the analysis (as also shown in the insets below the raster plots). Until the second stimulus, only trials with a stimulus1 that could be followed by two different stimulus2 values are considered; thereafter, trials with a stimulus2 that could be preceded by a smaller or larger stimulus1 are included. (Middle) Mean firing rate of the vS1 example unit for trials with sp2>sp1 is plotted in red and for trials with sp1 > sp2 is plotted in blue. Error bars show SEM. (Bottom) Time course of information for the same neuron is shown. Conditional MI between the firing rate of the neuron and rat’s choice is plotted. The green dotted curve and green band show mean ± SD resulted from the shuffled distribution.
(B) Similar to (A) but for a PL example unit.
(C) Percentage of vS1 units with significant information about animal choice (green) and stimulus sp (blue). Only correct trials are included.
(D) Similar to (C) but for PL units.
