Abstract:
Normal variation in human emotionality, in temperament and risk for affective disorders, is explained to a large degree by genetic variation. The sequencing of the human genome has made it possible to test the role of specific genes on measures of human emotionality, on risk for affective disorders, and on the brain systems that appear to mediate emotion-related phenotypes. A novel approach, called imaging genetics, has shown that several genes that impact on brain serotonergic signaling affect the development and function of circuits of the limbic system involved in emotional experience and behavior. © 2009 Published by null.
