This is your brain on politics: Neuroscience reveals brain differences between Republicans and Democrats

New research provides fresh evidence that choosing a candidate may depend largely on our biological make-up.

 

The study focused on the mirror neuron system, a network linked to a host of social and emotional abilities. After declaring their political affiliations, the subjects were given questionnaires designed to gauge their attitudes on a range of select political issues. Next, they were given “resting state” MRIs which made it possible to analyze the strength of connections within the mirror neuron system in both the left and right hemispheres of their brains; specifically the inferior frontal gyrus, supramarginal gyrus and angular gyrus.
