I like the idea that in humans, the cortex (and the cortex specifically, in conjunction with the thalamus, but definitely not the whole brain IMO) has a generative model that’s making explicit predictions about upcoming sensory inputs, and is updating that generative model on the prediction errors. For example, as I see the ball falling towards the ground, I’m expecting it to bounce; if it doesn’t bounce, then the next time I see it falling, I’ll expect it to not bounce.
