Cortical repesentation of the common fur of mysticial pad is situated outside poster-medial barrel subfield (PMBSF) in rat primary somatosensory cortex.Following neonatal vibrissectomy, stimulation of the common fur activates the neurone in PMBSF.We examined if sparing of the mystacial vibrissa from the neonatal ablation, which results in a very extensive increase of its cortical repesentation, would prevent the invasion of the common fur inputs into the PMBSF.The cortical representation were mapped with 2-deoxyglucose (2DG).It was found that six weeks after neonatal vibrissectomy sparing C3 vibrissa and common fur inputs were representes into the PMBSF.Their representation shifed from its normal location into the barriel field.This effect was observed in cortical layers II/III, IV and V.
