Epistasis effects of dopamine genes on interval timing and reward magnitude in humans.

Neuropsychologia - 1 Jan 2013

Balcı Fuat, Wiener Martin, Cavdaroğlu Bilgehan, Branch Coslett H

Abstract excerpt

We tested human participants on a modified peak procedure in order to investigate the relation between interval timing and reward processing, and examine the interaction of this relation with three different dopamine-related gene polymorphisms. These gene polymorphisms affected the expression of catechol-o-methyltransferase, which catabolizes synaptic dopamine primarily in the prefrontal cortex (COMT Val158Met...
