A 46 year old man with ischaemic infarction of the right parietal cortex had left hemianaesthesia when his eyes were closed. With eyes open, visual stimuli induced withdrawal of the arm and a burning pain in the numb side of the body. Visually induced central pain is a new clinical finding and may be related to damage of cells with anticipatory inhibitory function in the parietal association cortex.

一名46岁男性，右侧顶叶皮质缺血性梗死，闭眼时出现左侧半身麻醉。睁眼时，视觉刺激会引起手臂回缩以及身体麻木侧出现灼痛。视觉诱发的中枢性疼痛是一项新的临床发现，可能与顶叶联合皮质中具有预期抑制功能的细胞受损有关。
