我们研究了看到的和感觉到的触觉刺激的整合如何调节体感处理，并调查了视触整合是否依赖于刺激的时间连续性，以及它与预先存在的身体表征的一致性。在训练过程中，参与者观看了一只橡胶手或一个橡胶物体，这些橡胶手或橡胶物体与他们自己的手同步刺激，或者以不相关的方式被敲击。在随后的测试阶段，体感ERP记录到触觉刺激的左手或右手，以评估触觉处理是如何影响以前的视觉触觉经验，在训练过程中。一个增强的体感N140组件引起同步后，与不相关的，视觉触觉训练，无论参与者是否看到一个橡胶手或橡胶物体。这种早期效应的视觉触觉整合体感处理被解释为一个候选人的电生理相关的橡胶手错觉，是由时间的连续性，但不是由预先存在的身体表征。ERP调制观察超过200毫秒后刺激，表明注意偏向诱导的视觉触觉训练。当橡胶手的刺激和参与者自己的手在训练过程中不相关时，这些后期调制就不存在了，这表明预先存在的身体表征可能会影响触觉处理的后期阶段。
We studied how the integration of seen and felt tactile stimulation modulates somatosensory processing, and investigated whether visuotactile integration depends on temporal contiguity of stimulation, and its coherence with a pre-existing body representation. During training, participants viewed a rubber hand or a rubber object that was tapped either synchronously with stimulation of their own hand, or in an uncorrelated fashion. In a subsequent test phase, somatosensory ERPs were recorded to tactile stimulation of the left or right hand, to assess how tactile processing was affected by previous visuotactile experience during training. An enhanced somatosensory N140 component was elicited after synchronous, compared with uncorrelated, visuotactile training, irrespective of whether participants viewed a rubber hand or rubber object. This early effect of visuotactile integration on somatosensory processing is interpreted as a candidate electrophysiological correlate of the rubber hand illusion that is determined by temporal contiguity, but not by pre-existing body representations. ERP modulations were observed beyond 200ms post-stimulus, suggesting an attentional bias induced by visuotactile training. These late modulations were absent when the stimulation of a rubber hand and participants' own hand was uncorrelated during training, suggesting that pre-existing body representations may affect later stages of tactile processing.
