Neonatal facial nerve extirpations fail to produce alterations in the barrel field in the primary somatosensory cortex of mice

Abstract

Branches of the facial nerve were transected in newborn mice, resulting in paralysis of whisking of the mystacial vibrissae. After maturation, the brains were examined in Nissl preparations for alterations in the barrel field of the primary somatosensory cortex. There were no evident changes as a result of this intervention.
