• Dopamine β-hydroxylase (DBH), the enzyme that converts dopamine to norepinephrine, was measured in the CSF of 32 subjects. Those individuals with a low level of DBH in the CSF had significantly elevated profiles on the Minnesota Multiphasic Personality Inventory, suggesting a relationship between the central noradrenergic system and some aspects of personality in man.
