It is quite likely that the brain's relationships are not just 2- or 3-dimensional, but rather very highly multidimensionally interconnected. When neural nets seriously hit the scene 30-odd years ago (I read a lot of the early papers, even having to mail off to get some in those pre-Internet days), no one seriously thought they were the way the brain works, just that they presented the opportunity to simulate a tiny slice of the way brains might work. As Ted Nelson so perfectly puts it, "Everything is deeply intertwingled."
