Rats use their vibrissae for a variety of exploratory tasks including location of objects and discrimination of texture. This study examines recovery in vibrissal function following a unilateral ischemic injury to the somatosensory cortex. Vibrissal function was examined in adult food-restricted rats performing on a two-texture discrimination device. Animals were trained and tested until the criteria of >80% correct choices was demonstrated on three consecutive days. Ischemic rats were constrained to use the affected whiskers by clipping the ipsilateral vibrissae. One group was tested after ischemia, a second group was trained before ischemia and then tested, and a third group was pre-traine..View full abstract
