Methamphetamine (METH) is typically characterized as a more potent psychostimulant than amphetamine (AMPH), but few studies have directly compared the effects of these drugs at low, behaviorally activating doses that tend not to produce focused stereotypy. The objective of the study was to compare the effects of AMPH or METH treatment on locomotor activity(More)
The medial prefrontal cortex (mPFC) is a component of the mesolimbic dopamine (DA) system involved in psychostimulant-induced hyperactivity and previous studies have shown that altering DA transmission or D2 receptors within the mPFC can decrease this stimulant effect. The goal of this study was to investigate a potential modulatory role for D1 receptors in(More)
Reward-seeking behavior can be powerfully modulated by exposure to a conditioned stimulus (CS) that was previously associated with that reward. This can be demonstrated in a Pavlovian to instrumental transfer (PIT) task where presentation of a CS (e.g., tone and light) previously paired with a rewarding unconditioned stimulus (US; e.g., food) leads to(More)
