Arrow of TimeDileep George has conducted research into modeling the structure of the human neocortex and constructed artificial neocortical arrays that mimic thought processes. These arrays are arranged in a heirarcial structure, with some closely connected to sensors and others a level removed, and so forth. Each heirarchial level resolves the invariant portions of a signature of the inputs through learning. His example of the visual cortex’s ability to identify the difference between a dog and a helicopter independent of position, version or race through learning. An audio recording of Dileep’s paper is at http://www.itconversations.com/shows/detail732.html
The structure and organization of the neocortex requires a number of relationships and feedbacks including statistics, probability and temporal feedback. It occurs to me that the human perception of time may be inextricably linked to this temporal feedback. If time is not a fundimental feature of the universe, but instead simply a “rate variable” clocked by our own neocortex, then the time we have used as reference for all of our present science may be merely an artifact of our mind’s perception.
