Many theories of memory postulate that processing of information outlasts the learning situation and involves several different physiological substrates. If such physiologically distinct mechanisms or stages of memory do in fact exist, they should be differentially affected by particular experimental

A series of dihydro-1H-pyrrolo[1,2-a]imidazole-2,5(3H,6H)-diones were synthesized. These bicylic derivatives contain both the 2-pyrrolidinone and 4-imidazolidinone nuclei, already recognized as important for cognition enhancing activity. In addition, these structures maintain the backbone of piracetam and oxiracetam with the acetamide side chain

Previous studies have shown that food ingestion is not capable of inhibiting the GHRH-induced GH release in anorexia nervosa, at variance with what is observed in normal subjects. Moreover, a cholinergic alteration has been hypothesized in this disorder. In a

The effects of the nootropic drug oxiracetam on the K(+)-evoked overflow of [3H]D-aspartic acid ([3H]D-ASP), [3H]acetylcholine ([3H]ACh), [3H] gamma-aminobutyric acid ([3H]GABA), [3H]noradrenaline ([3H]NA) and [3H]5-hydroxytryptamine ([3H]5-HT) have been studied in superfused rat hippocampal slices. The overflow of [3H]D-ASP was enhanced

Cognition-enhancing effects of no-otropic drugs are currently ascribed to an increase in arousal level. In order to test this hypothesis, we studied the effects of three doses of oxiracetam (25, 50 and 100 mg/kg IP) on a radial maze task
