Adolescent And Adult Nicotine Exposure On The Acquisition Of Methamphetamine Self-Administration And The Reinstatement Of Extinguished Methamphetamine-Seeking In Male Rats, Joseph Allan Pipkin
Adolescent And Adult Nicotine Exposure On The Acquisition Of Methamphetamine Self-Administration And The Reinstatement Of Extinguished Methamphetamine-Seeking In Male Rats, Joseph Allan Pipkin
Theses Digitization Project
This study sought to determine the individual and combined contribution of adolescent and adult nicotine exposure on METH self-administration and METH-seeking behavior in male rats. Nicotine is a commonly abused substance among adolescents and is believed to be a "gateway" to other drugs of abuse. In support of the gateway hypothesis, cigarette smoking during adolescence is related to increased methamphetamine (METH) use in adulthood.

Theses Digitization Project
The purpose of this study was to determine if Fischer 344 (F344) rats, a strain which naturally shows deficits in social communication during adolescence, could be used as a model of the social communication deficits observed in autism. Thus, the goal was to determine if F344 rats would also show fewer emissions of isolated-induced ultrasonic vocalizations (an early onset form of social interaction) as compared to SD rats. Subjects consisted of 142 F344 rat pups (67 male and 75 female). Subjects were treated according to the "Guide for the Care and Use of Mammals in Neuroscience and Behavioral Research" under …
