While I don’t have time to discuss it in depth like I would, the neurological process for learning anything is called “long term potentiation (LTP)” which is the process of your brain creating new receptors and synapses as it learns to solve novel problems.

With Additional practice in things that are not novel LTP still occurs which is how you get really good at something as you begin to learn additional intricacies of the problem.

However with truly novel tasks, there is also a dopamine / reward loop which occurs in a part of the brain for all novel things (I believe the striatum? Can’t remember where right now).
