Ruiz, Casimira (2007). Cognitive Deficits and Individual Differences Resulting from Behavioral Sensitization to an Escalating Dose of Methamphetamine. Winner of a Sigma Xi Grant-in-Aid of Research.
Mentor: Dr. Anne Marie Brady
Sixteen rats were administered saline or an escalating dose of methamphetamine (meth) (3 days a week for 5 weeks, increasing 1 mg/kg to 5 mg/kg at 1 mg/kg a week). Locomotor activity of meth-treated animals resulted in sensitized (activity increased by 50% or more) and non-sensitized (activity did not increase by 50%) rats. Following a 4 week withdrawal period, rats were tested for conditioned place preference to determine the rewarding properties of the drug when compared to food. Additionally, rats were tested in a set-shifting task to assess cognitive impairment due to repeated meth use. Meth had no effect on either test for any of the three drug groups (sensitized, non-sensitized and saline).
