- Age modulates the effect of COMT genotype on delay discounting behaviorChristopher T Smith
Neurobiology Curriculum, University of North Carolina, Davie Hall, Chapel Hill, NC 27599 3270, USA
Psychopharmacology (Berl) 222:609-17. 2012..Based on reported age-related changes in frontal dopamine function and COMT expression, we hypothesized that the association of COMT genotype with delay-discounting behavior is modulated by age from late adolescence to young adulthood...
