Do Athletes Respond Differently To Academic And Social Stress? An Examination Of Cortisol And Perceived Stress Throughout A Semester In College Athletes And Typical College Students, Rita Rose Holak 2010 Connecticut College

Do Athletes Respond Differently To Academic And Social Stress? An Examination Of Cortisol And Perceived Stress Throughout A Semester In College Athletes And Typical College Students, Rita Rose Holak

Behavioral Neuroscience Honors Papers

In order to be a successful athlete, you must be able to perform well under stressful situations. Are athletes also better at responding to stress under other circumstances such as social and academic stress? The present study investigated the impact of exercise on salivary cortisol and perceived stress in college students. Cortisol was sampled throughout a semester as well as before and after a laboratory‐based stress test during the final exam period. It was found that athletes had the largest increase in cortisol between baseline and the final exam period and the sedentary students had the smallest increase. Also ...

The Effects Of Testosterone On Emotional Processing In Male Rhesus Monkeys (Macaca Mulatta), Hanna M. King 2010 University of Massachusetts Amherst

The Effects Of Testosterone On Emotional Processing In Male Rhesus Monkeys (Macaca Mulatta), Hanna M. King

Masters Theses 1911 - February 2014

The effects of testosterone (T) extend beyond reproductive behavior to the areas of cognitive and emotional functioning. While T effects on cognition have been extensively investigated, less is known about the role of T in the processing of emotional stimuli. Considering the role that T plays in aggressive behavior and dominance status, it is of particular interest to determine whether T modulates the processing of social threat. Due to their similarities to humans in brain organization, reproductive endocrinology and affective regulation, rhesus monkeys (macaca mulatta) provide an excellent model to investigate this relationship. In a within-subjects design, six male rhesus ...


Lost In Translation?: An Essay On Law And Neuroscience, Stephen J. Morse 2010 University of Pennsylvania

Lost In Translation?: An Essay On Law And Neuroscience, Stephen J. Morse

Faculty Scholarship at Penn Law

The rapid expansion in neuroscientific research fuelled by the advent of functional magnetic resonance imaging [fMRI] has been accompanied by popular and scholarly commentary suggesting that neuroscience may substantially alter, and perhaps will even revolutionize, both law and morality. This essay, a contribution to, Law and Neuroscience (M. Freeman, Ed. 2011), will attempt to put such claims in perspective and to consider how properly to think about the relation between law and neuroscience. The overarching thesis is that neuroscience may indeed make some contributions to legal doctrine, practice and theory, but such contributions will be few and modest for the ...


Play And Adversity: How The Playful Mammalian Brain Withstands Threats And Anxieties, Stephen M. Siviy 2010 Gettysburg College

Play And Adversity: How The Playful Mammalian Brain Withstands Threats And Anxieties, Stephen M. Siviy

Psychology Faculty Publications

Most mammals play, but they do so in a dangerous world. The dynamic relationship between the stresses created by their world and the activity of play helps to explain the evolution of play in mammals, as the author demonstrates in evidence garnered from experiments that introduce elements of fear to rats at play. The author describes the resulting fearful behavior and quantifies the fluctuation in play that results, and then he investigates how these are modified by increased maternal care or the use of benzodiazepines. In conclusion, he discusses how such research can help shed light on the neurobiology underlying ...

Circadian Wheel-Running Activity During Withdrawal From Chronic Intermittent Ethanol Exposure In Mice, Joseph Seggio 2009 Bridgewater State College

Circadian Wheel-Running Activity During Withdrawal From Chronic Intermittent Ethanol Exposure In Mice, Joseph Seggio

Joseph A. Seggio

Alcohol withdrawal is associated with affective–behavioral disturbances in both human alcoholics and in animal models. In general, these phenomena are potentiated by increased alcohol exposure duration and by prior withdrawal episodes. Previous studies have also reported locomotor hypoactivity during ethanol withdrawal in rats and mice, but only in novel test environments and not in the home cage. In the present study, we examined the effects of withdrawal from chronic intermittent ethanol (CIE) vapor exposure on the level and circadian periodicity of wheel-running activity in C57BL/6J mice. CIE treatment resulted in reductions in wheel-running activity compared with plain-air controls ...

Influence Of Perinatal Exposure To A Polychlorinated Biphenyl Mixture On Learning And Memory, Hippocampal Size, And Estrogen Receptor-Beta Expression, Howard Cromwell 2009 Bowling Green State University

Influence Of Perinatal Exposure To A Polychlorinated Biphenyl Mixture On Learning And Memory, Hippocampal Size, And Estrogen Receptor-Beta Expression, Howard Cromwell

Howard Casey Cromwell

Abstract. Perinatal exposure to PCB has been reported to cause a variety of health effects including endocrine disruption, and immunologic, reproductive, neurologic, and behavioral deficits. In the present study, a mixture of two PCB congeners, one non-coplanar (PCB 47) and one coplanar (PCB 77), were administered to young female Sprague-Dawley rats by route of maternal dietary consumption (either 12.5 ppm or 25.0 ppm, w/w). Impact on learning and memory were examined by radial arm maze on postnatal day 24-27. After behavioral tests were completed, the rats were transcardially perfused, and brains were excised. Immunohistochemistry for ER- β ...


Perinatal Exposure To Polychlorinated Biphenyls Alters Social Behaviors In Rats, Howard C. Cromwell 2009 Bowling Green State University

Perinatal Exposure To Polychlorinated Biphenyls Alters Social Behaviors In Rats, Howard C. Cromwell

Howard Casey Cromwell

Perinatal exposure to polychlorinated biphenyls (PCBs) leads to significant alterations of neural and hormonal systems. These alterations have been shown to impair motor and sensory development. Less is known about the influence of PCB exposure on developing emotional and motivational systems involved in social interactions and social learning. The present study examined the impact of perinatal PCB exposure (mixture of congeners 47 and 77) on social recognition in juvenile animals, conspecific-directed investigation in adults and on neural and hormonal systems involved in social functions. We used a standard habituation–dishabituation paradigm to evaluate juvenile recognition and a social port paradigm ...
