Piracetam is a nootropic agent that has been shown to improve cognitive performance in a number of animal model systems. Piracetam is reported to be used widely as a means of improving cognitive function in children with Down's syndrome (DS). In order to provide a preclinical assessment of the potential efficacy of piracetam, we examined the effects of a dose range of piracetam in the Ts65Dn mo...

Furthermore, the lack of an adequate animal model of Al...

The effects of various nootropic candidates on mescaline-induced head-twitches were studied in mice. The number of head-twitches induced by mescaline (100 mg/kg, s.c.) was significantly reduced by idebenone (32 and 100 mg/kg, i.p.), minaprine (0.32-10 mg/kg, p.o.) and nebracetam (100 mg/kg, p.o.). Cholinesterase inhibitors such as tetrahydroaminoacridine (1 and 10 mg/kg, p.o.), NIK-247 (10 and ...

Effects of newly synthesized nootropic and anxiolytic dipeptide Noopept on inhibitory synaptic transmission in hippocampal CA1 pyramidal cells were investigated using patch-clamp technique in whole-cell configuration. Bath application of Noopept (1 microM) significantly increased the frequency of spike-dependant spontaneous IPSCs whereas spike-independent mIPSCs remained unchanged. It was sugge...
