Most theories agree that it must involve an integration of activity from many different parts of the brain to produce a single unifying awareness of the world around us, but the exact way in which this works has remained something of a mystery.

Now however a breakthrough made by Mohamad Koubeissi and his colleagues at the George Washington University in Washington DC has provided a unique glimpse in to the way that our brain deals with consciousness. By stimulating a part of the brain known as the claustrum with electricity the researchers were able to effectively render a subject conscious or unconscious on demand."I would liken it to a car," said Koubeissi. "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."
