在具有视交叉正中矢状切面的猫中，一些视觉皮层神经元不仅可以由同侧眼通过直接的基因皮质通路驱动，还可以由对侧眼通过相反的视觉皮层和胼胝体驱动。刺激对侧眼时观察到的感受野和反应特征与刺激同侧眼时观察到的感受野和反应特征非常相似；给定细胞的2个单眼感受野位于与垂直子午线密切接触的异位半视野的对应点上，从而增加了视觉空间，形成了一个穿过垂直子午线并在其两侧均匀延伸的双眼感受区。
In cats with midsagittal section of the optic chiasm, some visual cortex neurons can be driven not only by the ipsilateral eye, through the direct geniculocortical pathways, but also by the contralateral eye, through the opposite visual cortex and corpus callosum. The receptive fields and the response characteristics observed upon stimulation of the contralateral eye are very similar to those observed upon stimulation of the ipsilateral eye; the 2 monocular receptive fields of a given cell lie in corresponding points of heteronymous halves of the visual field in close contact with vertical meridian, thus adding in visual space and forming a binocular receptive area which crosses the vertical meridian and extends equally on either side of it.
