Figure 1.
Acute administration of PACAP (50pmol/.25ul) into the VMN did not alter hedonic orofacial responses to a 1% sucrose solution. (A) A VMN PACAP microinjection 15 minutes prior to a taste reactivity test did not significantly alter appetitive responses (lateral tongue protrusions & paw licks) to the sucrose solution. (B) A VMN PACAP microinjection 15 minutes prior to a taste reactivity test did not significantly alter aversive responses (gapes & paw flails) to the sucrose solution. Data from each subject are presented, as well as the group mean. * = p <.05 compared to vehicle injection.
