New brain imaging method sheds light on the nature of consciousness
"Using a newly developed imaging technique, researchers in the U.K. have for the first time observed what happens to the brain as it loses consciousness. The method known as "functional electrical impedance tomography by evoked response" (fEITER) uses a 32 electrode array to scan the brain at a rate of 100 times a second and by applying this as an anaesthetic drug takes effect, researchers are able to build a real-time 3-D video that will aid in better understanding of how the brain functions and the nature of consciousness. […] So far the evidence supports the theory put forward by Oxford University’s Professor Susan Greenfield that consciousness is not an ON/OFF state but more like a dimmer switch."
