A new MRI technique plus theoretically flattening out all the brain's convoluted layers shows a 3-D grid layered out much as an electrican would wire a building or a computer, each layer at 90 degrees from the next:

If you straighten out its folds, Wedeen argues, the brain consists of a three-dimensional grid of fibres."-"Moving up the primate tree, there are progressively more folds and curves, but the underlying grid structure remains."-In other words, we have to go through a computational "normalization" process in order to force the brains of more complex primates to adhere to the grid structure. -Note that this also implies that the difference between man and other primates is a difference of degree in terms of structure and not of kind.
