From: Central administration of dipeptides, beta-alanyl-BCAAs, induces hyperactivity in chicks
Effect of i.c.v. injections of β-Ala-L-Ile, β-Ala-L-Leu and β-Ala-L-Val on total spontaneous activity (upper panel) and total distress vocalization (lower panel) in chicks for 10 min postinjection. Figures in parentheses indicate the number of chicks in each group. Results are expressed as means ± S.E.M. Groups with different letters are significantly different (P < 0.05).
