概括

手幻觉 (RHI) 与整体感知无关,但移动RHI表明整体感知敏感性 (IS) 增强了对身体的所有权. 在移动RHI中的积极运动也可以提高那些具有较低整体感知精度 (IAcc) 的人的行动力.

科学领域:

神经科学是一个神经科学.
心理学心理学心理学
肉体感官研究研究

背景情况:

手幻觉 (RHI) 通过视觉触觉刺激来展示虚幻的身体所有权.
以前的研究发现心脏整体受体和RHI强度之间存在不一致的联系.
自愿行动在连接整体感受和身体所有权方面的作用需要进一步研究.

研究的目的:

调查移动RHI和整体感受措施之间的关系.
探索如何整感准确性 (IAcc) 和整感敏感性 (IS) 影响移动RHI和代理.
为了澄清整体感觉和身体感官之间的动态联系.

主要方法:

在观察假手时,通过主动或被动的手指敲击诱导的移动RHI进行了检查.
通过心跳计数任务使用整体感知精度 (IAcc) 测量整体感知.
使用自我报告问卷评估整体感知敏感度 (IS).

主要成果:

在整接收测量和古典视觉触觉RHI之间没有发现显著的关联.
更高的整感觉敏感度 (IS) 与更强烈的身体所有权感在移动RHI中相关,无论运动类型如何.
在移动RHI中的积极运动增强了代理感,但仅在具有较低整感准确度 (IAcc) 的个体中.

结论:

这项研究揭示了整体感觉在塑造身体感官中的不同维度的不同作用.
在动态的RHI范式中,对身体所有权至关重要的是间接感知 (IS).
互感准确性 (IAcc) 与自愿行为相互作用,以调节代理感.

Major Somatic Sensory Pathways

Major Somatic Sensory Pathways

Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

Somatosensation

Somatosensation

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
