ABSTRACT: This preprint compares aversive taste behaviors caused by conditioned taste aversion with responses to naturally aversive quinine while recording gustatory cortical activity and jaw-opener EMG. The results identify two classes of gaping: a taste-specific class aligned with cortical taste and palatability dynamics, and a rapid generalized class linked to internal state and heightened vigilance.
