Sandidge and Ward: Brain enzymes may affect work styles
Last month, we wrote about the brain enzyme catechol-O-methyltransferase (COMT). The role of COMT is clearing dopamine from the brain area responsible for planning and decision-making. In the 1990s, scientists studying COMT learned the enzyme was really twins. There are two different types of COMT. One type sweeps away dopamine quickly. The other type clears more slowly – four times more slowly.
