Sensory signals that are anticipated by the brain do not propagate further; only unpredicted signals are processed as learning.

“if your neurons are already firing in a way to anticipate those signals those signals just confirm the firing and then they're done they don't make it any further into the brain so when you're predicting well your experience is constructed completely by your brain the signals from the sensory surfaces are there just to confirm or to change the signals so if there's things you didn't anticipate then those um errors of prediction those are the signals that are propagated and become compressed and stuff and we have a special name for that in science we call it learning”
