and if i may add to the principle 5 bit more
"pathways are not really isolated structures. in a sense every pathway in the brain has a relationship to every other pathway, given by their mutual position in this single universal grid structure"
these pathways arent the neurons themselves and does not make any sort of information processing. however, they transfer information from neuron to neuron, this way connecting the neurons and allowing interaction between them and in a larger scale between the brain areas. i should add that those are just the major highways in the brains, illustrating more how even more distant areas are connected. neurons themselves organize each other close to other neurons processing similar things and are connected to other neurons which are at close range and related to similar concepts.
