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.

左顶叶梗死后形状、质地和物体的麻木感：1例报告

麻木感是一种现象，患者可以偶然以高于预期的速率正确响应体感刺激，但不能有意识地感知相同的刺激。此前，麻木感已被报道用于对患者自身身体的刺激进行触觉定位。在这里，我们描述了一名涉及触摸物体的麻木感患者。左顶叶梗塞后患者无法识别大部分体感刺激，但可以正确选择形状、质地和物体刺激，其频率比预期的要高。
