A. Injection of orexin (0.9 nmol) into the paraventricular nucleus of the hypothalamus of ethanol-drinking rats (n = 8) increased ethanol consumption during the first hour post-injection. B. Injection of orexin significantly increased the number of ethanol drinking bouts, while leaving the size and duration of bouts relatively unaffected. Values are mean ± S.E.M.; **p < 0.01, *p < 0.05.
