Consciousness on/off switch discovered


Doctors discovered that stimulating the claustrum with electrodes caused the patient’s consciousness to fade out, and return when stimulation ended. They performed a few tests to ensure it wasn’t just memory loss. Now, it’s just one patient (it’s not exactly common to stick electrodes that deep in the brain, and this is the first claustrum targeted). What I find interesting is that this was predicted by Francis Crick, who was working on a paper on this very possibility just before he passed away.

TSA tells UK airport security: confiscate broken and out-of-battery gadgets

Nice one!

…In spite of it being rather a big deal to go poking electrodes into somebody’s brain, I’m surprised that this sort of research moves this slowly; that they only just got around to stimulating this part of the brain seems, I dunno… tardy.
