Except for the part where they say " *When we perceive something, the information does not end up in a specific part of our brain*.". You'll have to take it up with the people who concluded that in their study if you disagree. If you looked at a computer you would also see electrical activity that was > not local and constantly moved from one part to another. > No, not like this. What the brain does would be as if you plugged in a flash drive and waves propagated the contents of the flash drive throughout the RAM, HD, and CPU, rolling back and forth mingled in with all of the other processes going on. > And if it were perceiving its surroundings, as a Mars rover might, to > evaluate its next move it would obviously have to process data stored in > memory as well as sensor information. > It would be hard for it to process data stored in memory if it was circulating around the entire system, mixed with everything else. As time goes on, I suspect that we will see more and more of these kinds of studies. The brain does have mechanisms, but it is not a machine. It does computer, but it is not just a computer.
