It has been demonstrated that neurogenesis can sometimes occur in the adult vertebrate brain, a finding that led to controversy in 1999. However, more recent studies of the age of human neurons suggest that this process occurs only for a minority of cells, and the overwhelming majority of neurons comprising the neocortex were formed before birth and persist without replacement.
It is often possible for peripheral axons to regrow if they are severed. A report in Nature suggested that researchers had found a way to transform human skin cells into working nerve cells using a process called transdifferentiation in which "cells are forced to adopt new identities."

Famous quotes containing the words regeneration and/or nerve:
“Typically, the hero of the fairy tale achieves a domestic, microcosmic triumph, and the hero of myth a world-historical, macrocosmic triumph. Whereas the formerthe youngest or despised child who becomes the master of extraordinary powersprevails over his personal oppressors, the latter brings back from his adventure the means for the regeneration of his society as a whole.”
—Joseph Campbell (19041987)
“our nerve filaments twitch with its presence
day and night,
nothing we say has not the husky phlegm of it in the saying,
nothing we do has the quickness, the sureness,
the deep intelligence living at peace would have.”
—Denise Levertov (b. 1923)
