Interocular transfer of habituation in pigeons: mediation by tectal and/or posterior commissures

Interocular transfer of the habituation to diffuse photic stimuli was demonstrated to be almost complete in pigeons. Birds submitted to visual Wulst ablation or supraoptic commissure lesion performed in much the same way. In contrast, when the tectal and posterior commissures were lesioned, pigeons failed to show interocular transfer of that learning process.
