Using The Suprachiasmatic Nucleus As A Model System To Assess Tolerance And Withdrawal To Alcohol, Jonathan Houghton Lindsay

Doctoral Dissertations

Alcohol abuse induces many disorders including depression, metabolic syndrome, and sleep disturbances. The strong link between alcohol abuse and sleep problems, along with the close connection between sleep and circadian rhythms, led us to investigate ethanol’s effects on the circadian clock. Previous work has shown that acute ethanol blocks photic phase shifts in vivo and glutamatergic phase shifts in vitro. However, neural systems become tolerant to ethanol across different timeframes. Despite both ethanol tolerance and ethanol withdrawal syndrome being listed as criteria for developing alcohol use disorders, little is known about how ethanol tolerance and withdrawal induced hyperexcitability develop and …
