Habituation of acoustic startle is disrupted by psychotomimetic drugs: differential dependence on dopaminergic and nitric oxide modulatory mechanisms.

abstract：BACKGROUND:It has recently been shown that acute alcohol globally impairs 'prospective memory' (PM)-remembering to do something in the future (Leitz et al. in Psychopharmacology 205:379-387, 2009). In healthy, sober individuals, simulating future events at encoding enhances PM performance. AIMS:We therefore aimed to d...
