刺激大脑左半球的一个部位会引发一种令人毛骨悚然的感觉，感觉有人就在附近。精神病和神经科患者以及健康受试者都描述过这样一种奇怪的感觉，即有人在附近，而实际上没有人在场，但还不清楚这种错觉是如何由大脑触发的。在这里，我们描述了一位正在接受癫痫治疗的手术前评估的患者，由于对左侧颞顶交界处的局部电刺激，重复地诱导了这种感觉：幻觉者紧紧地“跟踪”了患者身体位置和姿势的变化。这些知觉可能是由于在颞顶交界处身体和自我的多感官处理过程中的干扰。
Stimulation of a site on the brain's left hemisphere prompts the creepy feeling that somebody is close by.The strange sensation that somebody is nearby when no one is actually present has been described by psychiatric and neurological patients, as well as by healthy subjects, but it is not understood how the illusion is triggered by the brain,. Here we describe the repeated induction of this sensation in a patient who was undergoing presurgical evaluation for epilepsy treatment, as a result of focal electrical stimulation of the left temporoparietal junction: the illusory person closely 'shadowed' changes in the patient's body position and posture. These perceptions may have been due to a disturbance in the multisensory processing of body and self at the temporoparietal junction.
