Figure 5.

Cross-context changes in RTs for the three actions. A, Top, Distributions of RTs for each of the three actions across the population. Left, RTs for NPs. Middle, RTs for LPs. Right, RTs for WTs. The sorting order was identical to that used in Figure 4 and was maintained for all three panels. Bottom, RT probability or the average RT count/trial across all neurons. While <10% of neurons exhibited RTs on any given trial, the rate was consistent across trials in both contexts. The vertical gray dotted lines in each panel denote the context switch point, whereas the single horizontal dotted line separates the population of neurons in half. B, Pie charts illustrating the relative proportions of RTs (black) and NRTs (gray) for each half of the population in each context. Note that neurons in the top half exhibited relatively more RTs in Context 2 than 1 whereas those in the bottom exhibited more RTs in Context 2 than 1. C, Pie charts illustrating the distribution of RTs by action type for the top and bottom halves of the population. The color key can be found at the bottom of B. Each half of the population exhibited different proportions of RTs for NP1, LP1, and WT1 from Context 1, and for NP2, LP2 and WT2 from Context 2. D, When the two halves of the population were recombined, the proportions of RTs dedicated to each action in each context were uniform. E, Pie charts showing the distributions of RTs for the three individual neurons whose rasters were shown in Figure 3. The neuron number corresponds to its position in A. While RT allocations were consistent with what was illustrated in the rasters, individual neurons may maintain, lose, or gain responses to actions in different proportions across the two contexts.
