I'm on business http://9taxi.in.net/ www.9taxi.com In people's descriptions of life-after-death experiences, there are light perceptions associated with visual function. If you were to say those experiences came from their brains, their visual cortex had to be activated. So with rats, we'd have to look at their visual cortex as well, which is what we did. Our data shows the visual cortex is highly activated in rats after the heart stops. There are no data about this for humans, but we would now know what to look for in humans because of this study.
