"Several lines of evidence support that dopaminergic neurotransmission plays a role in creative thought and behavior...
The results show a negative correlation between divergent thinking scores and D2 density in the thalamus,

and specifically thalamic function, is important for creative performance, and may be one crucial link between
creativity and psychopathology" http://dx.doi.org/10.1371/journal.pone.0010670
