[Article in Russian]


Effects of the nootropic drug phenibut on the transcallosal potential amplitude in the sensomotor brain cortex have been studied in rats. It is established that a single administration of phenibut in a dose of 25 mg/kg (i.p.) increases the transcallosal response amplitude, thus improving the interhemispheric transmission. This effect, being an objective evidence of the nootrope activity, confirms the drug status and corroborates the positive action of phenibut on the learning and memory processes.
