Squint-induced Modification of Visual Receptive Fields in the Lateral Suprasylvian Cortex of the Cat: Binocular Interaction, Vertical Effect and Anomalous Correspondence.

In this study, we investigated the receptive field properties of single cells in the lateral suprasylvian area of strabismic cats. More than three times as many cells could be driven by the non-operated than by the operated eye. Many more cells could be activated by the contralateral than by the ipsilateral eye. In both area 17 and the lateral suprasylvian area, more cells preferred horizontal rather than vertical or oblique orientations ('vertical effect'). In addition, a small percentage of cells in the lateral suprasylvian area showed an adaptive shift of spatial coordinates; this shift could provide the neural basis of anomalous retinal correspondence.
