Amygdala Grey Matter Volume and Face Activation Compared to Social Network Size

Amygdala volume and face activation activity have been linked to social network size. In the current study, these relationships were examined through analysis of Magnetic Resonance Imaging survey data 116 subjects, with a more detailed smaller sub-sample 20 subjects. Amygdalae structural volumes analyzed using Freesurfer, functional was Statistical Parametric Mapping, ultra-high-resolution susceptibility-weighted images in-house MATLAB scripts. Mean amygdala obtained in this experiment are line those reported previous research. Left correlated scores males, both left right hippocampus square root size one’s females. Significant correlations also observed between levels measures (n = 20).
