GABAA/alpha1 receptor agonists and antagonists: effects on species-typical and heightened aggressive behavior after alcohol self-administration in mice.

abstract：:The thymoleptics potentiate and modify the behavioral effects of apomorphine (probably the most specific dopaminergic agonist) as well as those of Dopa. The effect of the thymoleptics is not abolished by emptying of amine stores, and this together with other evidence suggests that these drugs facilitate the access of ...
