Wiring the human brain (Introduction)
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: > > http://www.newscientist.com/article/dn21647-human-brain-organised-like-a-3d-new-york-ci... the article: "But if a team led by Van Wedeen of Massachusetts General Hospital in Boston is correct, this staggering complexity arises from a seductively simple underlying structure, revealed using magnetic resonance imaging (MRI). 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.

\"Why is it, Master, that ascetics fight with ascetics?\"
\"It is, brahmin, because of attachment to views, adherence to views, fixation on views, addiction to views, obsession with views, holding firmly to views that ascetics fight with ascetics.\"
