The rubber-hand illusion (RHI), an illusion in which tactile sensations are referred to a synthetic alien limb, is enhanced in schizophrenia patients. Somatosensory evoked responses of the illusion were compared between schizophrenia patients and normal control subjects. Schizophrenia patients had significant alterations in long latency evoked responses during the illusion. These findings support the hypothesis of alterations in associative higher-level neuronal activity in schizophrenia. The findings support previous results pointing to alterations in associative brain regions in schizophrenia.
橡皮手错觉（RHI）是一种将触觉感受归属于人造异体肢体的错觉，在精神分裂症患者中会增强。比较了精神分裂症患者和正常对照受试者在该错觉中的体感诱发电位。精神分裂症患者在错觉期间的长潜伏期诱发电位有显著改变。这些发现支持了精神分裂症中联想性高级神经元活动改变的假说。这些发现支持了先前指向精神分裂症中联想性脑区改变的结果。
