Nootropic agent, improves learning and memory, and prevents impairment of cognitive functions. Its mechanism of action in not yet known, but it is suggested to modulate glutamatergic and cholinergic neurotransmission. Protein kinase C may be involved.

The effects of a nootropic drug, oxiracetam (50-100-200 mg/kg ip), and a potent antioxidant agent, ascorbic acid (62.5-125-250 mg/kg ip), administered alone or in combination, were investigated on scopolamine-induced amnesia in a mouse habituation test. The light-dark aversion test was

In the present study, the elevated plus-maze was used to evaluate memory in female mice. In Experiment 1, the mice retested on day 1, 4 or 7 after the initial session escaped from the open arm into the enclosed arm
Fruit of Avicennia marina (Forsk.) Vierh. (Acanthaceae) is used as a Chinese herb. Studies have found that it contains marinoid J, a novel phenylethanoid glycoside (PG) compound, but its neuroprotective functions are largely unknown. This study evaluated the effects of
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

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
