 How could people have these wonderful visions, have these experiences of floating out of the scanner going to another dimension going to God? How could that happen without the brain being turned on? In fact, we were so bemused by that first result that we repeated the whole thing. Got exactly the same results and then realized we'd actually discovered something really important that these drugs don't turn on the brain. They actually turn off the brain, but they turn off the parts of the brain which keep the brain doing what it's always done. When you turn those bits of the brain off, the brain can run free, it can do its own thing. It's like taking the conductor away from an orchestra or taking a school teacher away from a class of kids.
