对身体表面轮廓的感知通常被认为取决于丘脑和皮层中躯体感觉的地形学组织的神经地图。最近的神经生理学研究表明，这些地图是潜在的修改，通过改变他们的感觉输入。我们提出的证据表明，明显的形状和方向的身体可以在几秒钟内改变，通过使用肌肉振动，以产生本体感受的肢体位置的错误信息。根据手或脚相对于身体其他部位和测试室的位置，可以产生身体的系统感知扭曲和身体明显方向的变化。这些意见的维护一个准确的身体图式，空间方向，并为编码的眼位置的一些影响进行了说明。
Perception of the surface contour of the body is generally thought to depend on topographically organized neural maps of somatosensation in the thalamus and cortex. Recent neurophysiological studies indicate that these maps are potentially modifiable through alterations in their sensory input. We present evidence that the apparent shape and orientation of the body can be changed within seconds by using muscle vibration to generate proprioceptive misinformation about limb position. Depending on the position of the hands or feet in relation to the rest of the body and to the test chamber, it is possible to generate systematic perceptual distortions of the body and changes in the apparent orientation of the body. Some implications of these observations for the maintenance of an accurate body schema, for spatial orientation, and for the encoding of ocular position are described.
