Problems like anxiety and depression are caused by psychological and environmental factors, and are known to be influenced by genetic proclivities. However, it is still not clear how each factor affects the brain’s functions to induce anxious and depressive symptoms. To shed light on these interactions, a team from the Centre Émotion-Remédiation et Réalité Virtuelle (Center for Emotion Remediation and Virtual Reality, CNRS / UPMC / CHU Pitié Salpêtrière) has investigated the amygdala, a part of the brain that is hyperactive in individuals suffering from anxiety and depression. The researchers have shown that its activity can be modulated depending on the subject’s genetic makeup, personal history and cognition. These results suggest that the effects of psychotherapies on the cerebral activity of patients could vary according to their genetic traits. This work makes the cover story of the November 2011 issue of Human Brain Mapping.
