Extract:

Volume of left amygdala subregion predicted temperamental trait of harm avoidance in female young subjects. a voxel-based morphometry study reports a personality neuroimaging study on 56 young Japanese subjects with magnetic resonance imaging, voxel-based morphometry and the Temperament and Character Inventory (TCI).

The article reports particularly on harm avoidance and the amygdala, but they also report Talairach coordinates from contrasts on novelty seeking and reward dependence.

Related studies referenced in the articles are Rauch 2005,[1] Omura 2005[2] and Wright 2006.[3]

[edit] Persistence

The study found no significant clusters for persistence personality dimension.

[edit] Critique

  1. Statistical threshold is put on uncorrected (across voxels) levels (though SVC was done after this). There is neither correction across personality dimensions.
  2. There is small volume correction apply for some regions: left amygdala, prefrontal gray matter and right caudate nucleus.
  3. The authors only report about the positive correlation, — not the negative, that was done in the Amygdala gray matter concentration is associated with extraversion and neuroticism study.
