The De Renzi Rod Test was used to investigate the transfer of spatial tactile information between hands in acallosals and partial commissurotomy patients. The right-handed performance of young acallosals was impaired, confirming the results of an earlier study by Meerwaldt (1983). The adult acallosals, with one exception, showed no difference between right and left hand performances. Two partial callosotomy patients with sparing of the most caudal parts of the body of the callosum showed no difference between the hands. A third callosotomy patient with little, if any, sparing of the most caudal part of the body of the callosum showed a marked impairment when performing the tactile task with the right hand. The unimpaired performances of the adult acallosals are attributed to the use of ipsilateral pathways and the development of behavioural strategies. The callosotomy patients' results are consistent with the mapping by Pandya and Seltzer (1986) of the interhemispheric callosal pathways between the cortical parietal areas in non-human primates.
德雷尼棒测试被用于研究胼胝体缺失者和部分胼胝体切开术患者双手之间空间触觉信息的传递。年轻胼胝体缺失者的右手表现受损，证实了米尔瓦尔德特（1983年）早期研究的结果。除了一个例外，成年胼胝体缺失者的左右手表现没有差异。两名部分胼胝体切开术患者，胼胝体体部最尾端部分保留，双手表现没有差异。第三名胼胝体切开术患者，胼胝体体部最尾端部分几乎没有保留，用右手执行触觉任务时表现出明显受损。成年胼胝体缺失者未受损的表现归因于同侧通路的使用和行为策略的发展。胼胝体切开术患者的结果与潘迪亚和塞尔泽（1986年）对非人类灵长类动物皮质顶叶区域之间半球间胼胝体通路的映射一致。
