Amygdala gray matter concentration is associated with extraversion and neuroticism:

reports a study with voxel-based morphometry.

NEO PI-R Neuroticism and Extraversion are correlated with gray matter concentration from voxel-based morphometry.

[edit] Subjects

Subject group (help)
Right handed adults
Subjects/♂/♀: 41 / 19 /
Age: 23.8 ±5.4 (–)
Nationality: American
Approval: define approval
Databases:

A group of 41 right handed adults with 19 males were included in the study. The American group had a mean age of 23.8.

The study was performed at Yale University.

[edit] Results

The authors report amygdala change based on "small volume family-wise error correction at P<0.05". Other activations are P<0.001 uncorrected.
