TPE increases CTA-related c-Fos expression in GC. (A) Preexposure to salty and sour tastes (open bars) followed by CTA conditioning resulted in significantly higher c-Fos expression in GC, compared to WPE rats (gray bars); c-Fos in the TPE—CTA conditioning group was also significantly higher than all other groups. These results, and the fact that TPE did not enhance c-Fos in sham and LiCl-alone groups, demonstrate that TPE specifically impacts the pairing of the sucrose with LiCl, and not the processing of either independently. (B) (Left) BAT sucrose consumption (mL) across 15-min access to 15 mL sucrose was similar for TPE and WPE rats. (Middle) Lick rate for sucrose was similar for TPE and WPE rats during the entire 15 min BAT session. (Right) Initial lick-rate (average licks for the first 3 min of the BAT) was similar for TPE and WPE rats. Error bars represent SEM. (*) P < 0.05.
