Does the neurotransmitter dopamine have something to do with creativity?

Not specifically: Creativity is not from a single neurotransmitter, but is a complicated process involving a whole person and his/her entire brain. For instance, when we're very anxious, our creativity suffers because our alarm system amygdala is in charge -- we're just trying to survive. When we can relax, we see more possibilities, & find creative solutions. Our prefrontal cortex -- & more -- activate!

Some research: http://www.sciencedaily.com/releases/2010/05/100518064610.htm some connection between d2 system in highly creative people and in schizophrenia--surprising, as the relation between bipolar and creativity is known. But "studies have shown that Dopamine receptor genes are linked to ability for divergent thought" facility with metaphors perhaps in common--but in schiz. The metaphors are idiosyncratic.
