基于静息态fMRI的催眠控制呼吸研究

A Resting-State Functional MRI Study of Hypnosis for Respiration Motion Control

摘要: 催眠是一种被证明有效的、无害的心理学上的呼吸控制方法。文章通过对 13 位有催眠背景的心理咨询师被试进行催眠控制呼吸实验,由催眠师引导被试进行催眠,运用静息态功能磁共振的方法来研究催眠控制呼吸状态下脑功能的异常。结果显示:在催眠状态下,脑活动在视觉皮层(枕叶)、感觉运动皮层(中央前回、中央后回、布洛德曼 4、6 区)、后扣带回以及颞中回上升;在背外侧前额皮层、小脑后叶以及缘上回下降,并且在全脑大规模静息态功能网络范围内相关关系增强(正常态 r=0.64,催眠态 r=0.80)。此外,催眠状态下视觉皮层与运动皮层之间的功能连接增强。研究结果表明,视觉皮层和运动皮层在催眠控制呼吸的神经机制中发挥了重要的作用,其神经机制也可能与认知处理和感知处理密切相关。本研究结合了心理学以及脑科学进行了研究,为催眠的研究提供了一个认知脑科学的研究新视觉。

Abstract: Hypnosis is an effective psychological technology in respiratory motion control. In this study, functional magnetic imaging was applied to an intra-subject (n=13) design hypnosis experiment guided by hypnotists to analyze the respiratory motion control and neural activity in hypnosis. As a result, increased brain activities were observed in visual cortex, sensorimotor cortex, posterior cingulate cortex and middle temporal gyrus, and decreased in dorsolateral prefrontal cortex, cerebellum posterior lobe and supramarginal gyrus. Moreover, compared with normal state, enhanced correlation of brain activities (normal state, r=0.64; hypnosis state, r=0.80) was observed within large-scale resting-state networks. Increased connectivity between sensorimotor cortex and visual cortex in hypnosis was also observed, which implies their critical roles in neural mechanisms of hypnosis for respiration control and involvement of cognitive and perceptual processing therein. This study provides new insights for hypnosis study in psychology and cognitive neuroscience.
