Scientists Accidentally Discover The Brain’s Consciousness “Off Switch”

While performing deep brain surgery on a woman with epilepsy, neuroscientists from George Washington University stimulated an area of her brain that unexpectedly — and temporarily — caused her to lose awareness. It’s a discovery that could shed light on the very nature of consciousness itself.

“We describe a region in the human brain where electrical stimulation reproducibly disrupted consciousness,” write the scientists in their study. It’s an important finding as the “neural mechanisms that underlie consciousness are not fully understood.” No doubt, consciousness is still a profound mystery, so much so that we don’t know how it arises — or how it switches off.
