Too many! But I like the second one's (STANISLAS DEHAENE) idea that we can mobilize our old areas [of the brain] in novel ways.

I think so too. It reminds me of a study that showed that when we use tools (eg drive a car), we use the same brain areas as when we move are bodies. We literally use tools as an extension of the body. That's deep sensory and motor flexibility, that seemingly could exist without intelligence.
