The big idea is that everything the brain does can be implemented using neural machinery that was described 40 years ago [1][2]. The cortex produces a rich output (e.g. a long vector) that is compared to an inconceivably large number of stored contexts in the same space (e.g in the cerebellum). This is generally accepted as a way to store the motor commands for a sequence of movements. The big idea is that this neural mechanism underlies visual perception, thought, everything important the brain does. The purpose of these pages is to subject this idea to close scrutiny and to design tests, where possible, to discriminate between this and other ideas about neural representation.
