The Effects Of Adenosine Antagonists On Vigilant Attention In Sleep Restricted Rats, Morgan Crewe
The Effects Of Adenosine Antagonists On Vigilant Attention In Sleep Restricted Rats, Morgan Crewe
Masters Theses, 2010-2019
The relation between chronic sleep restriction and performance on the Psychomotor Vigilance Task (PVT) have been well documented in the human literature, with chronic sleep restriction as little as 7 hours per night resulting in significant impairment in sustained attention performance measured via the PVT. Recently, an analogous version of the human PVT has been developed for use with rodent models (rPVT). Recent studies have measured the effects of sleep restriction on rPVT performance, citing similar results found in the human literature. However, few studies to date have directly examined the role of adenosine accumulation during sleep deprivation in producing …
The Impact Of Fertility Cues On Intrasexual Competition And Threat Perception, Grant Ostrander
The Impact Of Fertility Cues On Intrasexual Competition And Threat Perception, Grant Ostrander
Masters Theses, 2010-2019
Humans are capable of detecting subtle fertility indicators that change across women’s menstrual cycle. One such indicator is the voice, which may change over the course of the menstrual cycle and provide fertility cues to listeners. Such cues provide an obvious advantage to men selecting mates, however research suggests that women can also detect these cues. Women may monitor the fertility of others to more effectively adjust their own mating strategies. By monitoring women’s skin conductance, cortisol, and testosterone responses to hearing high- and low-fertility female voices, the current study further investigated whether vocal cues of fertility may physiologically prime …
Sleep Deprivation And Voluntary Alcohol Consumption In Adult Rats, Charles M. Cowan Ii
Sleep Deprivation And Voluntary Alcohol Consumption In Adult Rats, Charles M. Cowan Ii
Masters Theses, 2010-2019
Alcohol is a psychoactive drug with a large userbase among adults across the globe. However, alcohol use also reduces the quality of sleep in the user. Historically, research has focused on the effects of alcohol on sleep architecture, but recent research has started to examine the effects of sleep deprivation on alcohol consumption. This research examines the effects of sleep deprivation on voluntary alcohol consumption in adult rats. Twelve Sprague Dawley rats were given ad libitum access to food, alcohol (7% solution), and water for the duration of this study. Subjects were then placed into non-moving forced exercise wheels to …
The Effects Of Chronic Partial Sleep Deprivation And Chronic Voluntary Alcohol Consumption On Δfos B Accumulation, Kristian Ponder
The Effects Of Chronic Partial Sleep Deprivation And Chronic Voluntary Alcohol Consumption On Δfos B Accumulation, Kristian Ponder
Masters Theses, 2010-2019
The present study explores the relation between sleep restriction and alcohol use and the neural substrates that result from chronic behaviors. Accumulation of the transcription factors ΔFosB is suggested as a possible outcome of chronic behaviors, such as addiction. Sleep is discussed as possible mediating factor in the relationship between ΔFosB and chronic alcohol consumption. There were four experimental groups in this study: Control (C), Sleep Deprivation only (SD), Alcohol Exposure only (AO), and both sleep deprivation and alcohol exposure (B). Levels of ΔFosB accumulation in the Nucleus Accumbens (NAc) revealed a significant main effect of sleep deprivation, but no …
