How could a gene lead to negative thinking? Well......the serotonin gene appears to make the amygdala, an emotional center of the brain, hyperactive.
Studies have found that a hyperactive amygdala is linked to extra sensitivity to negative stimuli, such as unpleasant images or events. People end up viewing the world negatively - noticing the weeds, not the flowers.- Cary Goldberg, The Boston Globe
