The retina already performs a low-artefact compression of about a 1:126
ratio. Bit rates into long-term memory may lie as low as few 10 bit/s,
however, albeit in a very dense coding. How much information the brain
can actually store is very much a conjecture. Accuracy of attractors
trapping input vectors can be measured. Don't ask me for refs, as first
papers are from the age of I. St. Prigogine.
