Figure 1. Grooming score following oxytocin microinjection into the central nucleus of amygdala.

Figure 1

(A) Grooming score average count showing 5-min behavior sampling curve of oxytocin (OT) 0.5 µg, OT 1 µg or saline (SAL) into the central nucleus of amygdala (CeA) group and OT 1 µg outside CeA group. (B) grooming score (sum of grooming behavior over 60 min) of OT 0.5 µg (checkered bar), OT 1 µg (black bar, n = 8) or SAL (open bar) inside CeA group and OT 1 µg outside CeA group (striped bar). The arrow indicates the moment of microinjections. Data shown represent the means. (‡ ‡) SAL inside CeA group vs OT 0.5 µg inside CeA group; (*) SAL inside CeA group vs OT 1 µg inside CeA group; (**) OT 0.5 µg inside CeA group vs OT 1 µg outside CeA group; (‡) OT 1 µg inside CeA group vs OT 1 µg outside CeA group. p<0.05, Poisson model.
