先天性无胼胝体可以用两只手进行触觉辨别，但两只手都不能熟练地识别触觉刺激的轨迹或执行独立的手指运动。手间传递与手内感知平行，具有辨别性但不是地形信息从一只手传递到另一只手。胼胝体在个体发育过程中的抑制作用显然是必不可少的，不是为了手之间的信息传递，而是为了获得每只手内差异化的感觉和运动。
Congenital acallosals made tactile discriminations with either hand, but neither hand was proficient in identifying the locus of a tactile stimulus or in performing independent finger movements. Intermanual transfer paralleled intramanual perception, with discriminative but not topographic information being transferred from 1 hand to the other. An inhibitory action of the corpus callosum during ontogeny is apparently essential, not for between-hand information transfer, but for the acquisition of differentiated sensation and movement within each hand.
