Effects Of Nicotine Exposure On Methamphetamine Oral Self-Administration, Extinction, And Reinstatement In Adolescent Rats, Zachary Robert Harmony Dec 2017

Effects Of Nicotine Exposure On Methamphetamine Oral Self-Administration, Extinction, And Reinstatement In Adolescent Rats, Zachary Robert Harmony

Electronic Theses, Projects, and Dissertations

Adolescence is a vulnerable developmental period in regards to drug initiation and use. The gateway hypothesis suggests that adolescent cigarette smoking may result in a heightened risk for methamphetamine use. However, little is understood about the role of nicotine on adolescent methamphetamine addiction. The aim of the present study was to determine whether early, late, or continuous adolescent nicotine exposure would alter oral methamphetamine self-administration, extinction, or reinstatement. A total of 164 male and female Sprague-Dawley rats were pretreated with saline or nicotine (0.16, or 0.64 mg/kg, sc) beginning on postnatal day (PD) 25 for 10 consecutive days. On PD …

Rumination Is Associated With Diminished Performance Monitoring, Ema Tanovic, Greg Hajack, Charles A. Sanislow Aug 2017

Rumination Is Associated With Diminished Performance Monitoring, Ema Tanovic, Greg Hajack, Charles A. Sanislow

Charles A. Sanislow, Ph.D.

Rumination is a construct that cuts across a variety of disorders, including anxiety and depression. It has been associated with deficits in cognitive control thought to confer risk for psychopathology. One aspect of cognitive control that is especially relevant to the content of ruminative thoughts is error processing. We examined the relation of rumination and 2 electrophysiological indices of error processing, error related negativity (ERN), an early index of error detection, and error positivity (Pe), a later index of error awareness. Consistent with prior work, ERN was negatively correlated with anxiety (i.e., more anxious individuals were characterized by larger ERNs). …

Burnout And The Hypothalamic-Pituitary-Thyroid Axis: A Methodological Comment, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

Because (a) burnout overlaps with depression and (b) depression has been associated with altered functioning of the hypothalamic-pituitary-thyroid axis changes in the activity of the HPT axis can be expected in burnout. Most probably, Guo et al.’s (2017) results are flawed by a severe form of the “healthy worker effect.”
