In the adult cat, a midsagittal section of the optic chiasm, which deprives each hemisphere of about half of its visual afferences, is followed after 6 weeks by a change in the callosal interhemispheric transfer, if one eye was occluded during the whole postoperative recovery period, thus depriving one hemisphere of direct visual messages related to patterned vision: with respect to controls only chiasmotomized, with binocular visual experience during an identical postoperative period, the deprived hemisphere displayed a significantly larger callosal afferent traffic while its own callosal efferences were on the contrary significantly reduced. This dissymmetry reveals that important postoperative changes can thus take place even in the adult animal.
在成年猫中，视交叉的正中矢状切面会使每个半球大约一半的视觉传入信息被剥夺。如果在整个术后恢复期间一只眼睛被遮挡，从而使一个半球失去与模式视觉相关的直接视觉信息，那么6周后胼胝体半球间传递会发生变化：与仅在相同术后期间有双眼视觉经验的单纯视交叉切开的对照组相比，被剥夺的半球显示出胼胝体传入流量显著增加，而其自身的胼胝体传出流量则相反显著减少。这种不对称表明，即使在成年动物中，术后也会发生重要的变化。
