The objective of the present experiment was to demonstrate whether four days of twice-a-day conditioned place conditioning produces a preference that is equivalent to that produced by using eight days of once-a-day training. Two doses of the…
1. The objective of Exp. 1 was to determine whether intracerebroventricular (ICV) injection of cathinone CATH (8.0-32 micrograms) would produce a dose-dependent conditioned place preference (CPP) and/or activation in rats. Results indicate that rats…
1. The objective of the experimentation was to determine whether nicotine (NIC, 0.8 mg/kg subcutaneously administered) would produce a conditioned place preference (CPP) in rats confined for thirty min to their less-preferred side in a three…
The Fawn Hooded (FH) rat strain possesses a genetic platelet storage pool deficiency which leads to an impaired capacity for platelets to store and release serotonin. While the relationship between this deficit and possible alterations in brain…
1. Previous studies indicate that rats trained to discriminate either cathinone or cathine from its vehicle have a diminished discriminative performance when tested 24 hours after a drug administration when compared to tests conducted after a vehicle…
1. Male Sprague-Dawley rats were trained to discriminate 0.4 mg/kg nicotine subcutaneously administered from its saline vehicle in a food-motivated operant discrimination task. Once trained, the discriminative performance was observed to be…
1. Experiments were conducted to investigate if the psychostimulant cathinone, like d-amphetamine, would produce generalization of the discriminative stimulus effects of nicotine. 2. Rats were trained to discriminate either 0.8 mg/kg cathinone from…
