Caffeine effects: interaction of drug and wheelrunning experience.
نویسندگان
چکیده
Male Sprague-Dawley rats were tested for wheelrunning following repeated injections of caffeine or distilled water after varying amounts of experience with caffeine and wheelrunning. Rats experienced with caffeine in combination with wheelrunning ran significantly more than rats experienced only with caffeine or wheelrunning alone. Results suggest that caffeine's stimulant effects are greater when subjects are experienced with wheelrunning while under the influence of the drug.
