Radiation Effects On Dopamine-Mediated Prepulse Inhibition In The C57bl/6 Mouse, Cara Nicole Zuccarelli Miller
Radiation Effects On Dopamine-Mediated Prepulse Inhibition In The C57bl/6 Mouse, Cara Nicole Zuccarelli Miller
Loma Linda University Electronic Theses, Dissertations & Projects
This study examined the effects of proton and gamma radiation on a dopamine-dependent sensory gating mechanism: prepulse inhibition of the startle reflex. The purpose of this research was to describe potential hazards of proton radiation to the central nervous system in long-term space fight and for proton therapy patients. Results from previous research indicate that startle behavior is modified by proton and iron radiation. Forty-eight 10-½ week old, male C57BL/6 mice were used to characterize the optimal parameters for the model (prepulse duration, probe duration, and stimulus-onset-asynchrony). Three hundred and fifty two mice were used to characterize the time course …
A Longitudinal Examination Of Flow As A Predictor Of Recreational Exercise, Brian Michael Chichester
A Longitudinal Examination Of Flow As A Predictor Of Recreational Exercise, Brian Michael Chichester
Loma Linda University Electronic Theses, Dissertations & Projects
Flow state is a valued psychological state of enjoyment and well-being. It is characterized by feelings of intrinsic self-reward and marked by nine dimensions theorized to contribute to flow state. Flow has been studied mostly in elite athletes, whom report highly lucid flow experiences; to a much lesser extent it has been studied in recreational exercisers. Most prior research methodologies involve experience sampling or qualitative techniques, such as interviewing. Only one demonstrably valid and reliable flow instrument is widely available for efficient, quantitative measure of flow experiences. This study measures flow longitudinally in a recreational exercising population by comparing a …
The Psychological Characteristics Of Obese Children, Thomas Taylor Mitchell
The Psychological Characteristics Of Obese Children, Thomas Taylor Mitchell
Loma Linda University Electronic Theses, Dissertations & Projects
Several studies along with the surgeon general of the United States have identified obesity as a national health issue. Research indicates that adult obesity treatment has relatively poor long-term effects. Consequently increased attention has been given to addressing obesity in children. This focus is particularly vital due to the fact that children are one of the populations showing the most rapid increase in overweight and obesity. The purpose of this study was to identify the some of the unique psychological characteristics of obese children by analyzing the intake data of children and adolescents attending the Loma Linda University Growing Fit …
