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.
