Developmental Influences On The Initial Subjective Rewarding Effects Of Etoh, Madison Waldron
Master’s Theses
The present studies were aimed to better understand developmental contributions to the risk for disordered drinking, and facilitate the long-term goal of developing effective interventions for individuals at high risk for alcohol use disorders. Experiment 1 assessed the effect of adolescent pre-exposure to ethanol on adult place preference, as well as, sex- and beta-endorphin(bE)-related contributions. Adolescent C57BL/6J and bE deficient mice were injected with 1.5g/kg of ethanol or saline and put back into their home cages. At the time of adulthood, we employed a single-exposure conditioned place preference paradigm (SE-CPP) to investigate the impact of preexposure on the initial subjective …

Background
Appropriate social interactions influence animal fitness by impacting several processes, such as mating, territory defense, and offspring care. Many studies shedding light on the neurobiological underpinnings of social behavior have focused on nonapeptides (vasopressin, oxytocin, and homologues) and on sexual or parent-offspring interactions. Furthermore, animals have been studied under artificial laboratory conditions, where the consequences of behavioral responses may not be as critical as when expressed under natural environments, therefore obscuring certain physiological responses. We used automated recording of social interactions of wild house mice outside of the breeding season to detect individuals at both tails of a distribution …
