    "We are examining the activity in the cerebral cortex /as a whole/. The 
brain is a
    non-stop, always-active system. When we perceive something, the information 
does
    not end up in a specific /part/ of our brain. Rather, it is added to the 
brain's
    existing activity. If we measure the electrochemical activity of the whole 
cortex,
    we find wave-like patterns. This shows that brain activity is not local but 
rather
    that activity constantly moves from one part of the brain to another."

    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 not 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. If you looked at a computer you would also see electrical activity that was not local and constantly moved from one part to another. 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.
