From Eric Kvaalen
You report on a woman becoming unconscious when electrodes in her brain stimulated “the claustrum”, suggesting this area of the brain could be the seat of consciousness (5 July, p 10)
However, we have a claustrum on each side of the brain. What would happen if her other claustrum were zapped? And can there be two seats of consciousness in one person?
