Rats were exposed in Experiment 1 to a novel flavor (CS) and in Experiment 2 to a second novel flavor (CS) paired with an apomorphine injection (UCS). Different groups received amygdala stimulation either after the consumption of the novel flavor or after the apomorphine injection. Results show that amygdala stimulation (a) had no effect upon recovery from neophobia, (b) had no effect upon development of taste avertion if administered after the CS, (c) disrupted development of taste aversion if administered within 3 hr after the UCS, (d) had no deleterious effect upon the development of apomorphine-induced illness. Results were interpreted as indicating an important role for the amygdala in taste-illness association.
