Dopamine helps with math rules as well as mood
To test this, the researchers trained rhesus monkeys to solve “greater than” and “less than” math problems. From other recent studies, the researchers knew that certain neurons in the prefrontal cortex answer such questions – one half of these “rule cells” was only activated when the “greater than” rule applied, and the other half was only activated when the “less than” rule applied.
Meanwhile, physiologically small amounts of various substances were being discharged near the relevant cells. These substances can have the same effect as dopamine – or the opposite effect – and could be adsorbed by dopamine-sensitive neurons. The surprising result was that stimulation of the dopamine system allowed the “rule cells” to perform better and to more clearly distinguish between the “greater than” and “less than” rules. Dopamine had a positive effect on the “rule cells’” quality of work.

This is the most important info I've seen in ages. I've been assuming it, but it's nice to have evidence.   Explains so much about mania.
I think I can structure the entire swirling super-rant in my head around this.
Nice...
