概括
过度饮酒会改变大脑活动,使其变得不那么动态和复杂. 酒精使用障碍 (AUD) 中这种神经生物学变化可能与降低的D2受体水平有关.
科学领域:
- 神经科学是一个神经科学.
- 成研究 研究成研究
- 医疗成像医学成像
背景情况:
- 沉重的酒精使用和酒精使用障碍 (AUD) 影响全球数百万人.
- 现有的AUD模型缺乏整合的全脑神经解剖学,功能和药理学数据.
研究的目的:
- 为了研究重度饮酒的个体的大脑动态.
- 开发一个全面的框架,整合神经解剖学,功能和药理学数据.
- 确定酒精使用障碍的神经生物学相关物和机制.

CNS Depressants: Alcohol and Nicotine
214
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
