Sensation seeking and early life stress are both risk factors for developing substance use disorders. Neural adaptations resulting from early life stress may mediate individual differences in novelty responsiveness, and, in turn, contribute to drug abuse vulnerability. Animal models also demonstrate associations between novelty responsiveness or early life(More)
Stress plays an important role in the development of addiction. Animals subjected to stress exhibit sensitized responses to psychostimulant drugs, and this sensitized response is associated with functional adaptations of the mesolimbic dopamine system. These adaptations likely arise from direct or indirect effects of glucocorticoids on dopaminergic neurons.(More)
Early life stress leads to several effects on neurological development, affecting health and well-being later in life. Instances of child abuse and neglect are associated with higher rates of depression, risk taking behavior, and an increased risk of drug abuse later in life. This study used repeated neonatal separation of rat pups as a model of early life(More)
Neonatal maternal separation (MS) has been used to model the effects of early life stress in rodents. MS alters behavioral responses to a variety of abused drugs, but few studies have examined its effects on methamphetamine sensitivity. We sought to determine the effects of MS on locomotor and stereotyped responses to low-to-moderate doses of(More)
Methamphetamine abuse impacts the global economy through costs associated with drug enforcement, emergency room visits, and treatment. Previous research has demonstrated early life stress, such as childhood abuse, increases the likelihood of developing a substance abuse disorder. However, the effects of early life stress on neuronal damage induced by binge(More)
