Assessment of working memory in rats using spatial alternation behavior with variable retention intervals: effects of fixed-ratio size and scopolamine.

abstract：:Rats were trained to self-administer cocaine in 1-h sessions on a fixed ratio 5 (FR5) schedule of reinforcement. Acquisition was carried out at a unit dose of 0.3 mg/kg and responding was then stabilized at cocaine doses of 0.1, 0.3, and 1.0 mg/kg/infusion. Pretreatments with naltrexone (0.1-10 mg/kg, SC) 20 min prior...
