How Our 'Lizard Brain' Influences Emotion and Social Perception

A study from Northwestern University reveals constant communication between the brain's social cognitive network and the amygdala, which processes emotions and fear. This connection helps integrate emotional significance into social interactions, potentially informing non-invasive treatments for anxiety and depression through techniques like transcranial magnetic stimulation (TMS). The findings highlight the evolutionary expansion of brain regions enhancing social understanding while linking them to ancient emotional centers.
