Who decides that a particular representation in the brain has zero mutual information with current sensory input? This requires a comparison of some sort (i.e. computation).
- eli_gottlieb 10y agoIt's a distributed computation that has been mostly precomputed, ie: brain connectivity. And a very popular theory of the brain says it does calculate second-order (precision/entropy) statistics about what it models.
- myflash13 10y agoThe combinatorially explosive amount of information that we deal with at every single moment is too large to be dismissed as "precomputed by brain connectivity". If such a large amount of computation could be "precomputed", it has massive implications on our understanding of complexity-theory. Besides it contradicts our subjective feeling of free will, which is why it is not a satisfactory answer for most people.
- wyager 10y ago>combinatorially explosive amount of information that we deal with at every single moment What are you referring to? The sensory input to the brain takes, as a ridiculously high upper bound, perhaps terabits per second. In reality it's probably a few megabits. It's really not much. Vision is, I suspect, by far the highest bandwidth input to our brain, and computer vision has met or exceeded human vision in many tasks.
