在保留胼胝体压部的部分连合切开术之前和之后测量患者的纵裂传输时间。传输时间的测量使用一个简单的反应时间范例与单手反应偏侧闪光在4度和8度的偏心。偏心度为8度时，术后转移时间长于术前转移时间，但偏心度为4度时，术后转移时间不长于术前转移时间。这些数据并不支持胼胝体通过运动纤维传递的时间总是比通过视觉纤维传递的时间快的观点。相反，他们认为，通过视觉纤维的胼胝体转移时间长于通过运动纤维的胼胝体转移时间，只有在大偏心闪光。
Interhemispheric transmission time was measured in a patient before and after partial commissurotomy sparing the splenium of the corpus callosum. The transmission time was measured using a simple reaction time paradigm with unimanual responses to lateralized flashes at 4 and 8 degrees of eccentricity. Post-operative transfer time was longer than pre-operative transfer time at 8 degrees but not at 4 degrees of eccentricity. These data do not support the notion that the callosal transfer time is always faster through motor rather than visual fibers. They rather suggest that the callosal transfer time through visual fibers is longer than the callosal transfer time through motor fibers only for flashes at large eccentricities.
