It is now widely accepted that hippocampal neurogenesis underpins critical cognitive functions, such as learning and memory. To assess the behavioral importance of adult-born neurons, we developed a novel knock-in mouse model that allowed us to specifically and reversibly ablate hippocampal neurons at an immature stage. In these mice, the diphtheria toxin(More)
A new nootropic preparation nooglutil (N-(5-oxynicotinoyl)-L-glutamic acid), a positive modulator of AMPA receptors for glutamate, administered intraperitoneally in a dose of 70 mg/kg reduced anxiety of rats in the Vogel conflict test after 24-h withdrawal from chronic diazepam treatment (4 mg/kg intraperitoneally for 45 days). Nooglutil (5 nM-750 μM) had(More)
The effect of piracetam at various doses on the behavioral and electrophysiological characteristics was studied, including the development of passive and active avoidance conditional reflexes in rats, their behavior in conflict situations, and the transcallosal evoked response (TER) in rabbit brain. In the dose range from 50 to 300 mg/kg, piracetam improved(More)
The effect of new nootropic dipeptides--noopept (N-phenylacetyl-L-prolylglycine, GVS-111) and its metabolite (cyclo-L-prolylglycine)--and a standard nootrope piracetam on the transcallosal evoked potential (TEP) in rat brain was studied. In the dose range from 150 to 300 mg/kg, piracetam increased the TEP amplitude, which exhibited a maximum after 1.5-2 h(More)
The effects of a single and repetitive administration of m-cholinoblocker scopolamine (Sc) to male rats on retention of step-through passive avoidance (PA) or active avoidance (AA) in a shuttle-box were compared. In case of PA Sc (1 mg/kg) was injected i.p. only 30 min before training, only 30 min before testing, or both before training and before testing.(More)
The authors studied the effect of a new nootropic agent with anxiolytic properties GVS-111 (ethyl ether N-phenylacetyl-L-prolylglycine) on formation of the avoidance reaction (AR) in rats and its functional disorders which were induced by two methods. In one case the stereotype of the relations between the stimulus, reaction and its consequence which(More)
