Visuomotor strategies in pattern discrimination learning in rats

Normal rats were trained on a series of visual tilt discriminations ordered from simple to difficult to measure their angular difference thresholds. The stereotyped visuomotor running pattern which the animal made was recorded for all angular differences binocularly and whilst the animal was monocularly patched. The results show that the running pattern does not reflect visual guidance strategies and can produce a visual field bias for the field ipsilateral to the preferred approach side.
