Modulation of MK-801 response by dopaminergic agents in mice.

abstract：:The behavioral consequences of prolonged continuous exposure to cocaine were examined in rhesus monkeys. Operant behavior was sampled for 0.5 h every 6 h, and cocaine was continuously infused through an intravenous catheter. Cocaine (4.0-32 mg/kg/day) initially caused reductions in the rate of responding for food and ...
