Examination Of Methamphetamine Reinstatement In Female And Male Rats: A Pre-Clinical Model Of Relapse, Steven T. Pittenger
Examination Of Methamphetamine Reinstatement In Female And Male Rats: A Pre-Clinical Model Of Relapse, Steven T. Pittenger
Department of Psychology: Dissertations, Theses, and Student Research
Methamphetamine (meth) dependence is often characterized by persistent and chronic relapse (i.e., return to drug use). There is growing pre-clinical and human evidence suggesting females are at greater risk to relapse. The set of studies presented in this dissertation extended this limited evidence by identifying sex-dependent neural substrates correlated with meth-triggered reinstatement (Experiment 1) and by examining sex-differences in reinstatement triggered by drugs of abuse that are commonly co-abused with meth (Experiment 2). Female and male rats were trained to self-administer meth, received subsequent extinction sessions, and then tested for reinstatement. In Experiment 1, rats were perfused following reinstatement testing …
