    Abstract:
    Neuroticism and extraversion are proposed personality dimensions for individual emotion processing. Neuroticism is correlated with depression and anxiety disorders, implicating a common neurobiological basis. Extraversion is rather inversely correlated with anxiety and depression. We examined neural correlates of personality in relation to depressiveness and anxiety in healthy adult subjects with functional magnetic resonance imaging during the cued anticipation of emotional stimuli. Distributed particularly prefrontal but also other cortical regions and the thalamus were associated with extraversion. Parieto-occipital and temporal regions and subcortically the caudate were correlated with neuroticism and affective measures. Neuroticism-related regions were partially cross-correlated with anxiety and depression and vice versa. Extraversion-related activity was not correlated with the other measures. The neural correlates of extraversion compared with those of neuroticism and affective measures fit with concepts of different neurobiological bases of the personality dimensions and point at predispositions for affective disorders.
