尼古丁成与大脑网络连接的改变有关,特别是在默认模式和执行控制网络中. 这些功能变化可以作为成的神经生物学标志物,并预测行为转变.
科学领域:
- 神经科学是一个神经科学.
- 成研究 研究成研究
- 神经成像是一种神经成像.
背景情况:
- 尼古丁成 (NA) 是一种主要的神经行为障碍,具有重大社会影响.
- 在特定的大脑网络中改变功能网络连接 (FNC) 被假设为NA的神经生物学的基础.
研究的目的:
- 调查尼古丁成 (NA) 和正常对照 (NC) 个体之间大脑网络的功能网络连接 (FNC) 差异.
- 探索FNC异常与尼古丁成的临床评估之间的关系.
- 为了确定尼古丁成的潜在神经生物学标志物.
主要方法:
- 分析了47名NA和35名NC患者的休息状态fMRI数据.
- 移动窗口分析评估了默认模式网络 (DMN),执行控制网络 (ECN) 和突出网络 (SN) 中的静态 FNC,标准偏差 (SD) 和变化系数 (CV).
- 患有NA的参与者根据法格斯特罗姆尼古丁依赖测试 (FTND) 纵向变化被分为成倾向 (AT),戒断倾向 (WT) 和稳定倾向 (ST).
主要成果:
- 患有NA的个体在背部DMN和右ECN之间的静态FNC减少,SD和CV增加.
- 在背部DMN和左侧ECN中观察到SD的增加.
- 与吸烟相关的评估相关的FNC变化,包括罗素吸烟原因问卷 (RRSQ) 和纵向FTND变化,特别是在WT子组.
结论:
- 观察到的DMN和ECN功能连接的改变可能会在尼古丁成的行为变化之前发生.
- 这些FNC变化代表了尼古丁成的潜在神经生物学标志物.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
