- -Differences Between Conservative Brains and Liberal Brains (Time.com)
"In a new study published in the journal PLOS ONE, a group of political scientists and neuroscientists have found that conservatives and liberals use different parts of their mind when making risky decisions, and that these differences in brain function can be used to predict party affiliation."
"They found that Republicans used their right amygdala, the part of the brain associated with the body’s fight-or-flight system, when making risk-taking decisions; Democrats tended to show greater activity in their left insula, an area associated with self and social awareness." 02-13

"For a country that features the word United so prominently in its name, the U.S. is a pretty fractious place. We splinter along fault lines of income, education, religion, race, hyphenated origin, age and politics. Then too there’s temperament. We’re coarse or courtly, traditionalist or rebel, amped up or laid-back. And it’s no secret that a lot of that seems to be determined by — or at least associated with — where we live."

"The scientists based their research on the brain scans of politicians and a handful of students--they found that the size of these two areas of the brain directly corresponded to the person's political viewpoints." 12-10

"Even in humdrum nonpolitical decisions, liberals and conservatives literally think differently, researchers show.
"Exploring the neurobiology of politics, scientists have found that liberals tolerate ambiguity and conflict better than conservatives because of how their brains work." 09-07
- Who Has a Better Brain: Liberals or Conservatives? (CBS News)
"The brains of people who call themselves liberals tend to have larger anterior cingulate cortexes than the brains of people on the opposite side of the political spectrum, the study showed. The anterior cingulate cortex is a collar-shaped region around the corpus collosum, a structure that relays signals between the right and left hemispheres of the brain."
"What about conservatives? Their brains brains tend to have larger amygdalas. The amygdala is an almond-shaped structure located deep within the brain."
"Based upon what brain scientists know about the function of the two brain regions, researchers believe the structural differences support the notion that liberals are better equipped to make sense of conflicting information while conservatives are better able to recognize a threat." 04-11
