We use the first lessons in Mind Up to learn about the brain and how our brain regulates. We name the parts of the brain including the prefrontal cortex, the amygdala, and the hippocampus. We talk about how the amygdala is the brain's super hero to help keep us safe. The amygdala controls our fight, flight, and freeze response. When our amygdala takes control, we're usually in the red, yellow, or blue zones. The prefrontal cortex is important in helping us learn and grow our brains. When we're in the green zone, our brain is in the prefrontal cortex and we can learn our best.
