Effects of brain lesions on taste-potentiated odor aversion in rats. Abstract Text:

Tadashi Inui,Tsuyoshi Shimura,Takashi Yamamoto,

Rats failed to acquire aversions to odor stimulus, which was followed 30 min later by an unconditioned stimulus (US). However, when the odor stimulus was accompanied by a taste stimulus, they acquired odor aversions as well as taste aversions. In this phenomenon, referred to as a taste-potentiated odor aversion, lesions of the amygdala disrupted both taste and odor aversions, whereas lesions of the parvicellular part of ventroposteromedial thalamic nucleus (VPMpc) or insular cortex (IC) disrupted taste aversion but attenuated only odor aversion. These results suggest that both taste and odor stimuli are associated with US in the amygdala and that taste inputs delivered to the amygdala through the IC and/or VPMpc play an important role in potentiation of odor aversion.
