研究了1例胼胝体损伤患者的基本视觉-运动整合的半球间转移时间（ITT）。总的来说，4291简单的反应时间收集在单手反应速示呈现的偏侧简单的视觉刺激在4°，6°和10°。尽管保留了一些通常需要两半球之间信息整合的能力（例如触觉命名、速示镜检查后的辅音阅读），但患者在任何偏心率下的基本视觉运动ITT任务（总体25.5 ms）中的表现与完全胼胝体切开的患者相似。这些研究结果表明，特定的胼胝体通道介导的基本视觉运动ITT和这些不包括喙和/或胼胝体压部。
The interhemispheric transfer time (ITT) of basic visuo-motor integration was investigated in a patient who had a lesion of the corpus callosum that spared the splenium and rostrum. Overall, 4291 simple reaction times were collected during unimanual responses to tachistoscopically presented lateralized simple visual stimuli at 4°, 6° and 10°. Despite retaining some abilities that typically require the integration of information between hemispheres (e.g. haptic naming, tachistoscopic later alized consonant reading) the patient performed similarly to completely callosotomized patients in a basic visuo-motor ITT task (overall 25.5 ms) at any eccentricity. These findings suggest that specific callosal channels mediate the basic visuo-motor ITT and these do not include the rostrum and/or the splenium of the corpus callosum.
