Buy Dreaming Herbs, Entheogens, Salvia Divinorum

I recently came across this article titled “Brain Electrodes Help Man Speak Again” at Forbes.

In sum, this guy has been a vegetable for 6 years until doctors stimulated his brain with electrodes. Now, he’s able to talk, express emotion, watch movies, and eat on his own without a tube.

Basically…

it sounds like he’s become a person again.

What does it say about who we are when a brain-dead man comes back to life after having parts of his brain electrically stimulated?

Isn’t this pretty strong evidence towards a materialistic understanding of personal identity and the self?

What does this mean then when I ask:

Are you the sum total of the processes going on in your brain?

If not, what else is there?
