        Not looking very charitable to the bottom-up, neuron machine view.

        The same description would apply to a computer. Information moves 
around and it
        is distributed over many transistors and magnetic domains.

    But it is eventually stored in particular addressed memory locations. It is 
    part of a continuous wave of activity of the entire computer.

    There is nothing in the cited article to show that particular information 
is never
    stored in some area.

Except for the part where they say " *When we perceive something, the information does not end up in a specific /part/ of our brain*.".

That refers to *when* we are perceiving it. That doesn't show that the information gained from that perception is not stored in some area in memory. Notice they refer to "when the subject is given a task", implying that not all information is waving around all the time.

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 
    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.

Actually that's exactly what my computer would do if I plugged in a thumb drive with a big complex program, e.g. a multi-player simulation game.

      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

It would be hard for it to process data stored in memory if it was circulating around the entire system, mixed with everything else.

On the contrary it can only process data in memory by copying it to registers and the CPU(s). And if it's a multi-tasking OS it will be "mixed" time-wise 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.

And I suspect you will still be saying that when Bruno's daughter marries a
