title: Monocular pattern discrimination learning after unilateral lesions of anteromedial cortex in rat.
abstract: 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. Preoperatively there was no difference between discrimination performance for either eye. Unilateral lesions of anteromedial cortex did not alter the monocular angular difference threshold. However, there was a reduction in discrimination performance for all angular difference comparisons. Animals showed a visual neglect for stimuli in the field contralateral to the lesion. The neglect was independent of the eye used for the discrimination.
