In agreement, several studies have demonstrated that PACAP modulates learning in physiological conditions.
Webextinction causes “reinstatement” of the CR. Presenta-tion of the CS outside of the context in which extinc-tion learning takes place leads to “renewal” of the CR. In light of these behavioral phenomena, current theories propose that extinction learning involves the formation of a new inhibitory association with the CS
