Popis: The Galanin N-terminal fragment (1-15)[GAL(1-15)] induces depressant- and anxiogenic-like actions in behavioural tests in rats. Since anhedonia is a core feature of depression, we have analyzed GAL(1-15) actions in anhedonic-like behaviour tests: saccharin Self-administration, Sucrose Preference test (SPT), Novelty suppressed feeding (NSF) and Female urine sniffing test (FUST). Three sets of experiments were conducted in the saccharin Self-administration. First, a dose-response curve of GAL(1-15) 1nmol, 3nmol or vehicle was performed. We have also compared the effects in the number of saccharine reinforcements of GAL 3nmol and GAL(1-15) 3nmol. In the last experiments, rats received GAL(1-15) 3nmol and the GALR2 antagonist M871 3nmol. In SPT, NSF and FUST we have analyzed the effects of GAL(1-15) 3nmol in the sucrose intake and preference, the latency of the first feeding episode and the female urine sniffing duration respectively. GAL(1-15)3nmol significantly decreased the number of reinforcement of saccharin self-administer (p
