Figure 2. Hemodynamic responses to oxytocin microinjection into the central nucleus of amygdala.

Figure 2

(A) Time-course of mean arterial blood pressure (ΔMABP, mmHg) and (C) heart rate (ΔHR, bpm) changes for 60 min after bilateral microinjections 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) Maximum responses in mean arterial blood pressure (ΔMABP, mmHg) at 50 min and (D) heart rate (ΔHR, bpm) at 5 min after bilateral microinjections of OT 0.5 µg (black-white bar), OT 1 µg (black bar) or SAL (open bar) inside CeA group and OT 1 µg outside CeA group (striped bar). The arrow indicates the moment of microinjections. Data presented are the means ± standard error of the mean. (*) SAL inside CeA group vs OT 1 µg inside CeA group; (**) OT 0.5 µg inside CeA group vs OT 1 µg inside CeA group; (‡) OT 1 µg inside CeA group vs OT 1 µg outside CeA group. p<0.001, Two-way ANOVA followed by Bonferroni's post hoc test.
