Data are means ± SEM of 4–6 mice per groups.* P<0.05 versus saline-injected wild type mice; # P<0.05 versus PP-injected wild type mice (90 minutes). NTS: nucleus tractus solitarus; AP: area postrema; ARC: arcuate nucleus of the hypothalamus; PVN: paraventricular nucleus of the hypothalamus; VMHDM: dorsomedial part of the ventromedial nucleus of the hypothalamus; LHA: lateral hypothalamic area.
