Infusion of 60 μM insulin did not alter extinction-reinstatement behavior but did reduce chow intake. (A) Extinction-reinstatement testing: Rate of magazine entries during presentation of the CS alone (Trials 1–5 and 11–15), and CS-US pairings (Trials 6–10) in vehicle (closed symbols) and insulin (open symbols) treated groups. Magazine entries during CS or CS-US presentations are shown by closed and open circles (Trial) and responses during the inter-trial-interval (ITI) are shown by closed and open squares. (B) Chow consumed in the home cage 1 hour immediately following the completion of extinction-reinstatement testing. (*p < 0.05).
