Ten normal controls and 45 brain-damaged patients, affected by lesions of the right (N = 25) or of the left (N = 20) hemisphere were given a test of two points discrimination, in order to check the hypothesis of a different organization of the somesthetic function at the level of the dominant and of the minor hemisphere. Somatosensory thresholds were measured at the level of the back of the hands and of the back of the feet by means of a modified version of the Weber two-point aesthesiometer. When patients with lesions of the right and of the left hemisphere were compared the following results were obtained: --somatosensory thresholds were higher on the contralateral than on the ipsilateral side of the body in both groups of patients; --ipsilateral defects were found in about 20% of the brain-damaged patients, but no relationship was put in evidence between laterality of lesion and ipsilateral sensory defects.
选取了10名正常对照者以及45名脑损伤患者进行两点辨别测试，这些脑损伤患者的右侧半球（N = 25）或左侧半球（N = 20）存在病变，目的是检验优势半球和非优势半球水平上本体感觉功能组织不同这一假设。通过改良版的韦伯两点触觉计在手背和脚背测量体感阈值。比较右侧半球和左侧半球病变的患者后，得到以下结果：——两组患者中，身体对侧的体感阈值均高于同侧；——约20%的脑损伤患者存在同侧缺陷，但损伤的侧别与同侧感觉缺陷之间未发现关联。
