The Effect Of Early Life Photoperiod Manipulation On Cocaine-Induced Behavioral Sensitization In Male And Female Japanese Quail, Shannon Elizabeth Eaton
The Effect Of Early Life Photoperiod Manipulation On Cocaine-Induced Behavioral Sensitization In Male And Female Japanese Quail, Shannon Elizabeth Eaton
Theses and Dissertations--Psychology
Estrogens seem to play a role in the locomotor activating effects of cocaine. Japanese quail provide a good model for hormonal manipulation as alterations of their photoperiod controls hormone levels. The current study aims to examine the role of early life photoperiod manipulation in cocaine-induced behavioral sensitization in quail. It was expected that if quail were raised on a short photoperiod, they would have a reduction in gonadal hormones and this reduction in hormones would affect the acquisition of cocaine-induced behavioral sensitization. Quail were raised on an 8L:16D or a 16L:8D light cycle. Following 2 days of habituation, quail were …

Addiction is a complex process in which behavioral sensitization may be an important component. While the behavioral effects of sensitization are well established, the intricate neurobiology of the phenomenon is still largely unknown. Dopamine systems mediate the induction of behavioral sensitization in adult rats, but there is a large amount of evidence showing that other neurotransmitter systems also modulate the induction process. For example, the α1b-adrenergic and 5-HT2A receptor systems are known to modulate the sensitized responding of adult rats, but the roles that these receptor systems play in the induction and expression of behavioral sensitization during the preweanling …
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 …
The Effects Of Extended Access To Methamphetamine Self-Administration On Dopaminergic Markers In The Striatum, Joe Luevano
The Effects Of Extended Access To Methamphetamine Self-Administration On Dopaminergic Markers In The Striatum, Joe Luevano
Open Access Theses & Dissertations
Methamphetamine (METH) abuse is a persistent problem in the U.S. and abroad. Escalation of METH use among independent users occurs for a variety of physiological and psychological reasons. Methamphetamine dependence may be attributed to the rewarding effect of this drug via the dopaminergic systems of the central nervous system (CNS). The presence of METH in the CNS increases synaptic release of dopamine. This increase in dopaminergic neurotransmission is thought to be directly attributed to the rewarding effects of METH. Following METH use, compensatory changes have been found to occur in the dopaminergic system during various periods of abstinence. It is …
