PAPINI Psicología rats ethanol Incentive downshift consummatory successive negative contrast The anxiolytic properties of ethanol (1 g/kg, 15% dose, i.p.) were studied in two experiments with rats involving incentive downshifts from a 32% to a 4% sucrose solution. In Experiment 1, alcohol administration before a downshift from 32% to 4% sucrose prevented the development of consummatory suppression (consummatory successive negative contrast, cSNC). In Experiment 2, ethanol prevented the attenuating effects of partial reinforcement (random sequence of 32% sucrose and nothing) on cSNC, causing a retardation of recovery from contrast. These effects of ethanol on cSNC are analogous to those described for the benzodiazepine anxiolytic chlordiazepoxide, suggesting that at least some of its anxiolytic effects are mediated by the same mechanisms. 2008 artículo científico 1794-4724 https://www.redalyc.org/articulo.oa?id=79926203 en http://www.redalyc.org/revista.oa?id=799 Avances en Psicología Latinoamericana application/pdf Universidad del Rosario Avances en Psicología Latinoamericana (Colombia) Num.2 Vol.26 |
