Numbsense is a phenomenon, wherein patients can correctly respond to somatosensory stimuli at a higher rate than expected by chance, but cannot perceive the same stimuli consciously. Previously, numbsense has been reported in tactile localization of stimuli on the patient's own body. Here, we describe a patient with numbsense that involved touched objects. The patient could not recognize the majority of somatosensory stimuli after left parietal infarction, but could correctly select shape, texture, and object stimuli more frequently than expected by chance.
麻木感是一种现象,患者在感知自身躯体上的触觉刺激时,能够以高于随机预期的速度正确做出反应,但却无法有意识地感知到这些刺激。在此之前,麻木感已被报道于触觉刺激的定位中。在这里,我们描述了一例涉及触诊物体的麻木感患者。该患者在左顶叶梗死后无法识别多数躯体感觉刺激,但能够以高于随机预期的频率正确选择形状、质地和物体刺激。
