概括
一个简短的10分钟集中注意力冥想 (FAM) 会话可以防止健康个体的行为状态疲劳. 这种冥想实践修改了注意力调节,并增强了认知功能,如休息状态功能性MRI (rsfMRI) 扫描所示.
科学领域:
- 神经科学是一个神经科学.
- 认知心理学 认知心理学
- 冥想研究 冥想研究
背景情况:
- 众所周知,延长冥想实践通过改变神经认知处理来减少疲劳.
- 简短的,单次集中注意力冥想 (FAM) 对状态疲劳及其神经机制在健康个体中的预防作用仍然在很大程度上未被探索.
研究的目的:
- 为了研究一次性,10分钟的FAM对从未进行过冥想的参与者的状态疲劳的预防作用.
- 使用休息状态功能性MRI (rsfMRI) 探索FAM对状态疲劳的影响的神经相关物.
主要方法:
- 56名健康,从未进行过冥想的参与者被随机分配到FAM或对照组.
- 在10分钟干预 (FAM或对照条件) 之前和之后进行了rsfMRI扫描.
- 参与者完成了60分钟的诱导疲劳的Go/NoGo任务;性能变化表明状态疲劳.
- 分析了休息状态功能连接 (rsFC) 的变化,并与状态疲劳相关联.
主要成果:
- 与对照组不同,FAM组在Go/NoGo任务中没有表现下降,表明疲劳预防.
- 在干预期间,fNIRS揭示了FAM组中中间前额叶皮层活动和连接性下降.
- rsFC分析显示,在FAM组中,左侧背中前额叶皮和右侧上额叶叶之间连接性增加.
- 对照组表现出后带带皮层和下回形之间连接性增加,这与注意力调节较差有关.
结论:
- 一次10分钟的FAM会有效地预防健康个体的行为状态疲劳.
- 通过增强认知力度和修改注意力调节,FAM似乎可以预防疲劳.
- 神经机制涉及功能连接的改变,特别是在与注意力相关的大脑网络中.

Atomic Nuclei: Nuclear Relaxation Processes
In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis, the precessing magnetic moments are randomly oriented around the z-axis. This...
Brain Imaging
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

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...
Altered States of Awareness
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
