A. Injection of galanin (1.0 nmol) into the paraventricular nucleus of the hypothalamus of ethanol-drinking rats (n = 8) significantly increased ethanol consumption over the 3 h post-injection. B. Injection of galanin significantly increased the size of ethanol drinking bouts, leaving the number and duration of the bouts relatively unaffected. Values are mean ± S.E.M.; **p < 0.01, *p < 0.05.
