All our memories are supposed to be stored in the Zero Point Field as well apparently.
Forget the professors name but he did experiments with rats brains by burning bits off with a "curling tong" to try and decipher which part of the brain held the memory ... then found that rats with practically all of their brains fried still remembered the course he had previously taught them.
All fascinating stuff.
