Dopamine Is a Rewarding Property and It Makes Neural Circuits Grow

Cocaine is a very interesting chemical because it's a dopaminergic agonist. What dopamine does is two things it makes you feel like what you're doing is worthwhile but also imagine that there's a bunch of neural circuits that are active and if they get ahead of dopamine or you do then those neural circuits get a little bit more powerful okay?
