Relationship between dopamine system genes and extraversion and novelty seeking.

Neuroscience and behavioral physiology - 1 Jul 2007

Golimbet V E, Alfimova M V, Gritsenko I K, Ebstein R P

Abstract excerpt

Dopamine transmission is known to play an important role in the reinforcement system of the brain. Studies have identified dopamine system genes whose polymorphic variants have been linked with the intensity of psychological traits reflecting the tendency to form behaviors characterized by impulsivity and the need for additional stimulation. The aim of the present work was to seek associations between...
