Figure 8.

Palatability processing is not affected by neurons with increasing firing rate post-BLAx. A, PI analysis (conventions same as Fig. 7) for the specific subgroup of neurons for which response magnitudes were reduced by BLAx. The growth in palatability content from the Middle to the Late epoch is significant for Intact sessions, but not for BLAx sessions. Within the Late epoch, there is a significant difference between Intact and BLAx. B, When analysis is restricted to the subgroup of neurons for which responses are enhanced BLAx, the significant palatability-related difference between Intact and BLAx sessions in the Late epoch disappears. Note the difference in y-axis scaling for the two panels. *p < 0.05.
