  1. Thanks Greg. Our emotion involves changes in the brain as well as the body.
  2. There are particular brain regions that are involved in the experience and
  3. expression of emotion. More than any other brain structure, the amygdala is
  4. active in controlling emotional experience, especially fear. It's been shown
  5. that people who have damage to the amygdala, don't actually show fear.
  6. Relatedly, psychopaths, people who are cold and remorseless individuals, who
  7. deceive and lie their way through life, often have an abnormally small
  8. malfunctioning amygdala. In addition, some violent criminals have been show to
  9. have tumors on their amygdala. The Amygdala is also involved in recognizing
  10. fear in other people, based on their facial expressions, but not other
  11. emotions. In addition, it's important to note, the left prefrontal cortex is
  12. most active when experiencing positive emotions, such as joy or happiness.
  13. However on the other hand, the right prefrontal cortex is most active when we
  14. experience negative emotions, such as fear or sadness. And when we experience
  15. pleasure, the hypothalamus is active.
