A tiny note for myself about "neurons that fire together, wire together": there's a temporal precendence, one cell should fire before the other so the learning, the actual wiring, can happen.
Listening to "CCN Course 2020, Neuron 11: Ions". It tells about membrane potential, sodium and potassium pumps, allowing our neurons to work.

…Have you ever thought that a neuron had evolved in a sea water?We carry a trace of an ancient ocean with us throughout our lives.
