Does caffeine have any effect on neurotransmitters, specifically GABA or dopamine?

Question

Is it a GABA or dopamine agonist/antagonist?

Thanks.

Answer 1

I vaguely remember a project I did for a class about adenosine receptors, and I know caffeine works on them somehow... might be worth investigating.

EDIT: Okay, I dug out my Psychopharmacology book, and it looks like caffeine blocks GABAa receptors, stimulates Ca2+ release within cells, and blocks the A1 and A2a receptors for adenosine.
