It can also be used as a way of making any of your views sound scientific. It's a simple formula — if you disagree with something, just say it releases dopamine and imply it must be dangerously addictive. It was clearly just a smokescreen for the views of gun-hating liberals. Now at this point, some of you may be worrying that I'm about to pour cold water on the pop science party and forever banish booty to the gossip columns, but I like to think that knowing the details is a more like putting acid in the punch bowl.

Dopamine is indeed involved in addiction, but it isn't a "pleasure chemical". In fact, dopamine has lots of functions in the brain — being involved in everything from regulating movement to the control of attention.

Explainer: What is dopamine?

In great part, its effects depend on which of the brain's pathways it is operating in. The wonderfully named tuberoinfundibular pathway regulates hormone release and is important in stimulating the production of breast milk. This is why an unfortunate side-effect of antipsychotic medication used to treat schizophrenia, which primarily alters the dopamine system, can be lactation, even in men.

But when you hear about dopamine in the press, it's usually a vague reference to the role of dopamine in the mesolimbic pathway — a small but important brain tract that connects a deep brain area called the nucleus accumbens to the frontal lobes.
