Size of Brain's Amygala Tied to Size of Relationship Network

RoseTracker| People with large amygdalas have larger social networks. Among species, those with larger and more comple social groups have relatively larger amygdalas, when body and brain-size ratios are compared.

Lisa Barrett, director of the Interdisciplinary Affective Science Laboratory at Northeastern University set out to compare amygdalas — the center of human emotion processing — among 58 people, aged 19 to 83. The study only studied real-life and not digital relationships.

Barrett’s findings confirmed the theory that people with the largest social networks have larger amygdalas. However, the size of their amygdalas did not have a correlation to quality of relationships or satisfaction with the social interactions. via TIME
