Habit formation involves strengthening neural synapses connecting cues, routines, and rewards, allowing electrical impulses to travel faster.

“The basil ganglia's job is essentially to make habits because without those habits we essentially can't evolve, right? Right? We just spend too much time in cognition. And what the basil ganglia helps encourage, and this is oversimplifying dramatically, but is it takes that cue, that routine, and that reward, and it puts them in a kind of circuit where the neural synapses connecting the behavior centers of those three items becomes thicker and thicker and thicker, which means that as a result, an electrical impulse can travel down that synapse faster.”
