Dissociation of the effects of scopolamine and d-amphetamine on a spontaneous alternation task. 1976

L Kokkinidis, and H Anisman

The immediate and carry-over effects of scopolamine and d-amphetamine were evaluated in a free running Y-maze spontaneous alternation task. The immediate effect of scopolamine (1.0 mg/kg) or d-amphetamine (5.0 mg/kg) was to reduce alternation to chance or to levels significantly below chance (perseveration), respectively. On a second, non-drug test day alteration decreased in saline treated animals, but increased among mice which received scopolamine on Day 1. In contrast, upon retesting in the non-drug state, the performance of animals initially treated with d-amphetamine resembled that of saline treated mice. Subsequent experiments revealed that these effects could not be attributed to drug effects on peripheral mechanisms, consolidation, residual drug action or drug dissociated learning. It was concluded that the behavioral effects of scopolamine and d-amphetamine are qualitatively different. Whereas scopolamine disrupts habituation, d-amphetamine induces perseveration independently of any effects on habituation.

D003913 Dextroamphetamine The d-form of AMPHETAMINE. It is a central nervous system stimulant and a sympathomimetic. It has also been used in the treatment of narcolepsy and of attention deficit disorders and hyperactivity in children. Dextroamphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulating release of monamines, and inhibiting monoamine oxidase. It is also a drug of abuse and a psychotomimetic. d-Amphetamine,Curban,Dexamfetamine,Dexamphetamine,Dexedrine,Dextro-Amphetamine Sulfate,DextroStat,Dextroamphetamine Sulfate,Oxydess,d-Amphetamine Sulfate,dextro-Amphetamine,Dextro Amphetamine Sulfate,Sulfate, Dextroamphetamine,d Amphetamine,d Amphetamine Sulfate,dextro Amphetamine

D012601 Scopolamine An alkaloid from SOLANACEAE, especially DATURA and SCOPOLIA. Scopolamine and its quaternary derivatives act as antimuscarinics like ATROPINE, but may have more central nervous system effects. Its many uses include an anesthetic premedication, the treatment of URINARY INCONTINENCE and MOTION SICKNESS, an antispasmodic, and a mydriatic and cycloplegic.
