Maybe you can try the mobile version, which is lighter: http://en.m.wikipedia.org/wiki/Hierarchical_temporal_memory > But from what you say, we might agree on this.

One of the things he mentions in the book, that I really like, is the possibility that the neocortex uses very long axons that go deep into the brain and back in a loop as a device to delay signals. The hypothesis is that it allows the mapping of temporal phenomena into a simpler atemporal pattern-matching problem. > > Then, if he claims that consciousness does not exist, well, we have a > problem. Agreed. > Perhaps the problem is not so serious because his theories do not depend on this assertion. It's more of a side remark, he seems to be annoyed by the consciousness issue and just avoids it. It's fair enough, I think. I don't have the book with me so I can't check. I will check in the summer if nobody else comes forward.
