Answer to Question 2
Answer: For people who test high in the trait of Neuroticism, serotonin may be an important neurotransmitter. The regions of the brain in which serotonin is particularly active include the amygdala, the hippocampus, and the hypothalamus, all of which are involved with mood regulation, depression, and anxiety disorders all of which would seem to also be related to Neuroticism. Low serotonin levels appear to be correlated to anxiety and depression, which are defining characteristics of Neuroticism. Genetic research suggests that people high in Neuroticism tend to inherit a variation of the gene (a short allele) that controls the brains ability to remove serotonin from the synaptic gap. This reduced serotonin activity puts the individual at risk for mood and anxiety disorders. Another gene variation that causes low serotonin levels also correlates with higher reactivity to fearful faces. People high in Neuroticism may have stronger and longer-lasting learned associations, especially to punishment as a result.
