Figure 6.

A–D, Excitatory inverse unit activity surrounding task-related time points in positive-contrast (A, B) and negative-contrast (C, D) session types. In this figure, units show an inverse contrast in the mixed-outcome versus single-outcome blocks. Specifically, units during positive contrast show a reduction in firing rates during the mixed-outcome block, while units during negative contrast show an increase in firing rates during the mixed-outcome block. A, Dorsal striatum food cup entry, 10 responses. B, Ventral striatum food cup entry positive contrast, 11 responses. C, Ventral striatum nose poke, 7 responses. D, Ventral striatum food cup entry negative contrast, 8 responses.
