Mephedrone (4‐methylmethcathinone) and d‐methamphetamine improve visuospatial associative memory, but not spatial working memory, in rhesus macaques

Abstract

These studies show that 4-MMC produces behavioural effects, including improvements in complex spatial memory and learning that are in large part similar to those of MA in non-human primates. Thus, the data suggest that the effects of 4-MMC in monkeys can be classified with classical psychomotor stimulants.
