研究了3例胼胝体病变患者的胼胝体病变部位与躯体感觉断开综合征的关系，以确定负责躯体感觉信息半球间传递的胼胝体区域。例1和例2均为后干病变，表现为左右手辨别性感觉传递障碍、左侧触觉失名和左侧躯体感觉失读。例3后干后腹侧部的病变没有表现出躯体感觉切断综合征的迹象。这些结果表明胼胝体后干的前部和/或背部对于辨别性感觉的半球间转移以及触觉命名和躯体感觉阅读所需的综合躯体感觉信息的重要性。
Somesthetic disconnection syndromes were investigated in relation to the sites of lesions in the corpus callosum in 3 patients with callosal lesions, in order to identify the callosal regions responsible for the interhemispheric transfer of somesthetic information. Cases 1 and 2 with lesions in the posterior truncus exhibited transfer deficits of discriminative sensations between the left and right hands, left-sided tactile anomia and left-sided somesthetic alexia. Case 3 with lesions in the posteroventral part of the posterior truncus showed no signs of somesthetic disconnection syndromes. The results suggest the importance of the anterior and/or dorsal part of the posterior truncus of the corpus callosum for interhemispheric transfer of the discriminative sensations and integrated somesthetic information necessary for tactile naming and somesthetic reading.
