title: The topography of amphetamine and scopolamine-induced hyperactivity: toward an activity print.
abstract: The increased locomotor activity induced by systemic injections of d-amphetamine or scopolamine in rats was studied in Digiscan Animal Activity Monitors. This multifactorial analysis of locomotion demonstrated that activity measures of horizontal (ambulatory), vertical (rearing), stereotypic, and rotational behaviors differed depending on dose and drug. The topographies of these activity variables may be unique for the dopaminergic and cholinergic systems underlying hyperactivity. These results are a first step toward a needed increase in the sophistication of behavioral pharmacological techniques, allowing for the development of specific activity prints for different classes of psychoactive agents.
