Scientists accidentally discover human 'off switch'

Scientists accidentally discover the human “off switch”. From the story: "I would liken it to a car," he said. "A car on the road has many parts that facilitate its movement — the gas, the transmission, the engine — but there's only one spot where you turn the key, and it all switches on and works together. So while consciousness is a complicated process created via many structures and networks — we may have found the key."
