概括

患有酒精使用障碍 (AUD) 的个人表现出更强的基于模型的行为,特别是涉及海马体,显示出更强的能力随着时间的推移故意减少酒精消费. 这表明新的治疗目标,以恢复饮酒的控制.

科学领域:

神经科学是一个神经科学.
心理学心理学心理学
计算精神病学是一种计算精神病学.

背景情况:

酒精使用障碍 (AUD) 通常与目标导向,基于模型的行为下降有关.
之前的研究并没有一致地发现AUD和没有AUD的个体之间的基于模型的控制差异.
连接基于模型的行为,神经活动和现实生活中的酒精控制的机制尚未得到充分理解.

研究的目的:

为了确定是否实验测量基于模型的行为可以预测未来的故意减少酒精消费.
探索与AUD患者基于模型的行为相关的神经特征.
为了研究基于模型的行为,神经标记和长期酒精摄入控制之间的关系.

主要方法:

67名患有AUD的参与者执行了一项顺序决策任务,以评估基于模型的行为及其神经相关物 (海马体,腹状条纹体).
通过基于智能手机的生态瞬间评估,收集了长期关于每天饮酒量和每周饮酒意向的数据,长达一年的时间.
统计分析检查了行为和神经标志物如何预测实际酒精消费与预期减少的对齐.

主要成果:

基于模型的行为及其在海马体和腹状条纹体中的神经特征影响了AUD患者控制酒精摄入的能力.
较高水平的基于模型的行为,加上更强的海马体和较弱的腹腔条纹性学习信号,预测了在日常生活中有意减少酒精的更大能力.
这些发现强调了目标导向行为的计算模型的生态有效性.

结论:

经过实验评估的基于模型的行为前性地预测了AUD个体的故意饮酒减少.
特定的神经标志物,包括海马和腹部条纹活动,是这种预测关系的关键调节者.
这些见解表明,针对个性化干预的潜在神经生物学知情目标,旨在加强对AUD中酒精使用的控制.

Substance Use Disorders Affecting Sleep

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.
Understanding the concepts of physical dependence,...

Timing and Consequences on Behavior

Timing and Consequences on Behavior

In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

Self-Presentation: Self-Monitoring and Self-Handicapping

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...
