How many ways can our brains be molded?  Researchers at Oxford believe they have zeroed in on the brain region involved in foreign accent syndrome, which causes patients' accents to shift suddenly.

Listen to a recent example of an English woman reporter who has foreign accent syndrome: before and after. 

The first known case was reported in 1941 and involved a Norwegian woman who was ostracized when she developed what her neighbors thought was a German accent after she recovered from shrapnel injuries.
