Fig. 5.

Discriminability of LPFC neurons (a) between rewarded and unrewarded trials observed on preferred and unpreferred reward blocks and that (b) between preferred and unpreferred reward blocks observed on rewarded and unrewarded trials. a, RNRDI values of individual LPFC neurons on the unpreferred reward block are plotted against those on the preferred reward block.b, RDDI values of individual LPFC neurons on unrewarded trials are plotted against those on rewarded trials. For botha and b, filled squaresindicate data in the cued liquid task, open triangles in the visible food task, and open circles in the cued food tasks, respectively. Dashed line indicates 45° line.
