| Amphetamine produces dramatic effects on both behavior and neurophysiology. Thus studies have focused on the stimulant action of amphetamine on the central nervous system. The lateral striatum is believed to be crucial in processing sensorimotor information and in initiating and maintaining movements. The dopaminergic system in the striatum has been specifically implicated in amphetamine's induction of several stereotyped behaviors. However, the neuronal mechanisms underlying amphetamine-induced behaviors have not yet been delineated. The specific purpose of this study was to determine the effects of amphetamine on neurons correlated with spontaneous head movement in the rat's dorsolateral striatum.;This study demonstrated a stimulant effect of amphetamine on vertical head movement, i.e., induction of head movements... |
