概括

实时fMRI神经反通过训练胰岛活动改善了心跳感知. 然而,单一的会话并没有改变情绪反应,这表明单独针对insula是不够的情感处理变化.

科学领域:

神经科学是一个神经科学.
认知科学认知科学
心理学心理学心理学

背景情况:

实时fMRI神经反 (NF) 提供了一种自愿控制大脑活动的方法.
岛屿在整感觉和情绪处理中发挥着关键作用.

研究的目的:

为了调查NF是否针对右侧胰岛素可以增强心跳感知和情绪反应.
探索胰岛神经调节和行为变化之间的联系.

主要方法:

54名参与者接受了实时fMRI神经反或虚假反,针对正确的insula.
在40分钟的NF课程之前和之后,评估了心跳感知和情绪评估.

主要成果:

NF组在心跳感知方面表现出显著的改善.
在神经调节中的个人学习预测了行为收益,但群体得分各不相同.
在行为或神经水平上没有观察到情绪反应的显著变化.

结论:

fMRI神经反可以通过岛内皮层神经调节来增强心跳感知.
针对岛屿的单个NF会话可能不足以改变情绪处理.

关键词:

关注注意力注意力注意力注意力功能磁力共振成像 (fMRI) 是一种功能共振成像.心跳感知感知感知岛屿岛屿是一个岛屿.整感知意识的意识意识.通过神经反,可以获得神经反.

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...
