Strokes or head traumas can produce very specific loss of abilities in adults.

I am not quite sure why this is being "debunked" now. Perhaps in part as status jockeying, i.e. "I'm ahead of the curve and not stuck with knowledge that was en vogue 10 years ago and all the Discovery-watching plebs has internalized" and in part a strange new dualistic movement that seeks to mystify the brain for some reason, perhaps in service of blank slatism.
