Or course it would be only interesting when ANN is some spiking neural network where speed of signal propagation is function of length of connections between neurons. But this effect could be simulated even in 3D space, it's simple - if some signals go faster then others, faster signals going to look like they teleported from one to the other part of the brain, teleported = passed using shortcuts of additional dimension. What's the additional dimension gives is more place for asynchonious communication, I think. It’s very easy to connect neurons in artificial neural networks using more then 3 dimensions…

Out of the box thInking sometimes can be off the reservation thinking of course, but I am constantly wondering what we are missing given our sensory and scientific limitations.

I'm reading it the same way I believe you are reading it: That the grids being imaged are only the myelinated axons of neuron bodies that are forming these grid patterns, and that they the fibers aren't communicating with eachother, they are simply traveling either to or from other areas on the same hemisphere of the cortex, to the other hemisphere via the corpus callosum or to other brain regions via the peduncles. That has significance I think, but I also think a lot of people might misread this into thinking the grey matter of the cerebral cortex is arranged into some sort of grid.

The finding is about the structure of white matter, right? That is, about layout of myelinated fibres? If so, it doesn't really matter for brain circuits work, if the fibres intersect at right angles, since there is no synaptic connection between them (since they are isolated by myelin). Therefore, there's nothing about internal brain logic, only some physical matter of packing tight bunch of cables. Please correct, if that is wrong. Please, could someone enlighten me?

Complexity develops from elementary starting conditions. Many puzzles can be resolved by analysing the basic facts. Science works this way. There it's a lesson there for our politicians, l think.

That limitation reduces wiring choices, so it reduces adaptability. “If they can turn in just four directions: left, right, up or down, this may enforce a more efficient, orderly way for the fibers to find their proper connections — and for the structure to adapt through evolution, suggest the researchers.”
