In two experiments the relationships between methylamphetamine induced stereotyped behaviour and locomotory activity, startle reactivity, and orienting responsiveness were investigated in laboratory rats. Experiment I showed that administration of 5 mg/kg methylamphetamine, compared to 0.5 mg/kg methylamphetamine or saline, resulted in increased stereotypy,(More)
The development of tolerance to the hyperactivating effects of methylamphetamine was studied in the laboratory rat. The results of Experiment I indicated that tolerance did develop. In Experiment II these indications were confirmed and the time course of tolerance was plotted. It appeared that the development of tolerance could be divided into two phases:(More)
