[The effect of N-acetylaspartic acid on the processes of memory and learning in rats]

The effects of a neurospecific substance N-acetyl-aspartic acid on memory and learning processes were investigated after intraperitoneal and oral administrations in rats. N-acetyl-aspartic acid was shown to restore the passive avoidance reaction in electroshock and scopolamine amnesias as well as in natural extinction. Chronic injections of N-acetyl-aspartic acid improved the learning in water maze but exerted no effect on the acquisition and retention of the active avoidance reaction in the shuttle box.
