Psychological resilience is very strongly associated with happiness. If you are happy, you are managing your stress well, and if you are stressed you are probably not happy. It is hard to imagine being stressed and happy at the same time. Both experiences are functions of activity in the prefrontal cortex. However, it isn’t activity in the entire prefrontal cortex that relates to these experiences, but rather when there is more activity on the left side than the right side. When there is more left activity than right activity, people report feeling happy and appear calm.
