For more than a century, scientists have been trying to figure out exactly what consciousness really is, how it works and where it comes from.
And while many questions remain to be answered, it appears some researchers have now discovered what they call an "on/off switch" for human consciousness.
A group of scientists at George Washington University say they were able to switch off a woman's consciousness by electrically stimulating a single area of the brain.
The research was published this week in the Journal of Epilepsy & Behavior and claims the scientists discovered the "switch" on accident while working to pinpoint the cause of the patient's seizures.
