Analysis of spontaneous regeneration of olfactory structures with emphasis on myelination and re-innervation of cortical areas

► We analyzed the re-innervated cortical areas in neonatally LOT-transected rats. ► We demonstrated ectopic LOT myelination in neonatally LOT-transected rats. ► Regenerated fibers were confined to the regions of the anterior olfactory cortices. ► Ectopic myelination of LOT occurred only at a specific site near the rhinal sulcus.
