Neuropharmacogenetics and behavioral genetics.

Genetic studies of neurotransmitter processes to date differ from most behavioral genetic studies in that the former have rarely considered individual variability, have tended to look only for single-gene effects, and generally have overlooked or ignored environmental influences. After examining these differences, we suggest that a rapprochement between the two fields will yield synergistic benefits in studies of the genetics of neuropharmacological processes as they affect behavior.
