Excessive alcohol consumption results in neurodegeneration which some hypothesize is caused by neuroinflammation. One characteristic of neuroinflammation is microglial activation, but it is now well accepted that microglial activation may be pro- or anti-inflammatory. Recent work indicates that the Majchrowicz model of alcohol-induced neurodegeneration results in anti-inflammatory microglia, while intermittent exposure models with lower doses and blood alcohol levels produce microglia with a pro-inflammatory phenotype. To determine the effect of a repeated binge alcohol exposure, rats received two cycles of the four-day Majchrowicz model. One hemisphere was then used to assess microglia via immunohistochemistry and while the other was used …

Do Rats Consume Ethanol To Regulate A Negative Emotion Induced By A Successive Negative Contrast Procedure?, Andrew Dieterich
Seton Hall University Dissertations and Theses (ETDs)
According to the self-medication hypothesis, individuals may consume drugs or alcohol, or engage in other behaviors in order to reduce a negative emotional state (Khantzian, 1985; Gross, 2013; Crum et al., 2013). Rats experiencing a negative state induced by various stressors (Bertholomey et al., 2010), or a decrease or loss in reward value of a sucrose solution (Manzo et al., 2015; Manzo et al., 2014) demonstrate increased consumption of alcohol. I used successive (SNC) and anticipatory negative contrast (ANC) procedures to further examine this hypothesis and the previous findings (Manzo et al., 2015), that rats increase consumption and preference for …
Moderate Ethanol Consumption Results In Cognitive Protection From Alzheimer’S Disease, Dementia, And Related Cognitive Decline: A Critical Review, Sean P. Coffinger
Moderate Ethanol Consumption Results In Cognitive Protection From Alzheimer’S Disease, Dementia, And Related Cognitive Decline: A Critical Review, Sean P. Coffinger
Butler Journal of Undergraduate Research
Moderate ethanol preconditioning, a result of prolonged moderate alcohol intake, serves as a protective process by staving off cognitive decline while providing neuronal protection through several mechanisms. These individual mechanisms are relatively well known, however a comprehensive and integrated conversation of ethanol’s protective tendencies is lacking from literature and the field of neuroscience. First, a review of the leading theories behind moderate ethanol preconditioning’s biological and cognitive benefits is presented, including overviews of neuroprotective, antioxidant, and neurotropic mechanisms responsible for neurological benefit. Secondly, an integrative model is presented, incorporating all research into a novel collaborative model. An additional discussion regarding …
