概括

心灵游荡与大脑活动有关,但它的神经模式对每个人来说都是独特的. 个性化大脑模型对于理解这种常见的精神状态至关重要.

科学领域:

认知神经科学认知神经科学
神经成像是一种神经成像.
个人差异个人差异

背景情况:

心灵流浪是一种常见的日常经历,但神经成像研究往往使用人口平均值.
之前关于心灵漫游和大脑活动的研究,特别是默认模式网络 (DMN),由于个人内部数据有限,缺乏个人特定的见解.

研究的目的:

通过使用密集样本的人来调查心灵漫游的神经基础.
探索与不同人之间心灵漫游相关的保留和可变的大脑网络模式.
评估心灵流浪的预测模型的概括性.

主要方法:

功能性磁共振成像 (fMRI) 用于三个人,他们报告了数百次心灵漫游的情节.
精确的功能映射被用来估计个体内的大脑网络.
基于Connectome的预测建模被用来识别特有的功能连接模式.

主要成果:

在个体层面上发现了迷思和默认模式网络 (DMN) 激活之间的可靠关联.
DMN活动的时间和涉及到心灵漫游的特定大脑网络在不同个体之间有很大的差异.
奇异的功能连接模式预测了个体内的思维流浪,但在它们之间显示出有限的概括性.

结论:

心灵游荡在个体之间表现出既保留的,又可变的神经表征.
心灵流浪的神经相关的个体间变异突出了个性化神经成像方法的需要.
异形 (个体特异) 模型为理解脑经验关联提供了重要的科学和潜在的临床价值.

High-Level and Low-Level Awareness

High-Level and Low-Level Awareness

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Reason and Intuition

Reason and Intuition

The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Subconsciousness and No Awareness

Subconsciousness and No Awareness

The concept of subconscious awareness refers to the processing of information below the level of conscious thought, which significantly influences both behaviors and decisions. It is also known as waking subconscious awareness. This complex level of cognition operates without the direct awareness of the individual, facilitating rapid and simultaneous handling of multiple information streams.
An illustrative example of subconscious processing is its role in problem-solving. Often, individuals...

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
