Sure, it sounds like it would make sense, but that's not necessarily how the brain actually works.

This study doesn't really seem to prove or even suggest anything either way, assuming GP's evaluation of their methodology is correct.

"Armchair neuroscientist" is not a game anyone can play well. (I say this because I know several actual neuroscientists, and they are constantly telling me about ways the brain works that are very counterintuitive.)
