概括
基于表面的形态测量揭示了可卡因使用障碍 (CUD) 中大脑结构的广泛变化. 这些变化,特别是在右侧的胰岛,可预测CUD状态,并可作为诊断生物标志物.
科学领域:
- 神经成像是一种神经成像.
- 神经科学是一个神经科学.
- 成研究 研究成研究
背景情况:
- 可卡因使用障碍 (CUD) 给全球健康带来了重大挑战.
- 以前的研究主要使用基于voxel的形态测量来检测CUD的灰质变化.
- 基于表面的形态测量 (SBM) 提供了对皮层厚度,表面积和平均曲率的详细见解,这对于理解CUD的结构性大脑变化至关重要.
研究的目的:
- 用SBM调查CUD中的异常神经解剖学模式.
- 确定这些异常模式是否可以作为CUD的潜在诊断生物标志物.

207
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

01:15Drug Abuse and Addiction: Pharmacological Phenomena
489
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...
