I started having a realization last night, that maybe I'm not even using my own brain for learning in the first place, that's why I feel this is alien to me. The function as I perceive it is just that the brain is for interpreting the visual input along with some sensory input from the rest of the body, directing the impulse through the spine to the organs of the body. I don't see it doing anything other than that, so the idea of there being a "learning" by manipulating the "activation function" of neurons, I don't see where that has a use in the human body.
Maybe I'm just that slow.
