Corpus callosum section disrupts motor behaviour strategies during visual discrimination learning in rat.
Monocularly patched rats were trained on a series of visual tilt discriminations ordered from simple to difficult to measure the angular difference threshold of each eye. The stereotyped running pattern which the animal made was also recorded. Callosal section disrupted a preoperatively established running pattern and produced an ocular neglect; the animal's performance dropped to chance when it used the eye ipsilateral to the preferred side of approach.
