24hr kaolin intake (A), chow intake (B), and body weight change (C) following an acute intraparenchymal mNTS administration of exendin-4 (0.05μg/100nl) or vehicle. In a two-bottle CTA learning paradigm, mNTS administration of exendin-4 did not produce a CTA when compared to vehicle injections (D); however, fluid intake for the vehicle-paired flavor was suppressed in the testing session compared to previous CTA testing sessions in this report. In separate rats, a CTA was produced following mNTS injection of vehicle compared to a non-injection condition (E). Data are mean ± SEM, * = p < 0.05 vs. vehicle.
