%Inj/g of I-PACAP ± unlabeled PACAP in olfactory bulb (Olf), occipital cortex (OC), hypothalamus (Hyth), hippocampus (Hip), cerebellum (Cb), and pons-medulla (PM) at 30 min after i.n. administration. Unlabeled PACAP produced significant increases (* p < 0.05) in OC and Hyth and arithmetic increases in other brain regions (Panel A) and a significant increase in %Inj/ml in serum (Panel B) as assessed by t-test.
