概括
使用脑电图 (EEG) 测量呼吸注意力的一致性揭示了正念的客观神经标志物. 较高的后置默认模式网络 (pDMN) α活性表明注意力一致性较低,并与主观注意力减少有关.
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
- 心理生理学 心理生理学
背景情况:
- 对呼吸等内在信号的间接注意对于正念至关重要.
- 研究整感觉注意力是具有挑战性的,因为依赖主观的措施.
- 用于外部注意力的响应一致性,在内部注意力任务中未得到充分利用.
研究的目的:
- 在整感注意任务中调查响应的一致性.
- 使用脑电图 (EEG) 探索整感觉注意力的神经相关性.
- 检查与年龄相关的差异和与主观正念的联系.
主要方法:
- 在324名参与者 (15-91岁) 中测量了呼吸监测任务的响应一致性.
- 同时的EEG记录了任务期间的大脑活动.
- 评估了与外受体抑制控制和主观正念的相关性.
主要成果:
- 呼吸监测的一致性与外受抑制控制正相关.
- 在任务中,alpha波段活动高于静止状态.
- 较高的后置默认模式网络 (pDMN) α活性与较低的响应一致性和较低的主观注意力有关.
结论:
- 增加的pDMNα活性是不一致的感知注意力的客观神经标志物.

High-Level and Low-Level Awareness
250
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
156
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.
