Impact of positive feelings and negative feelings on brain cell regeneration and degeneration.

Summary: Did you know your brain cells actually break their own DNA to help you learn and make memories? It sounds scary, but it is a totally normal process! Usually, your cells fix these breaks right away. However, as we get older or if we get sick, our brain cells have a harder time making these repairs. If the DNA stays broken, the cells can get weak and eventually die. Scientists are now exploring how our good and bad feelings might speed up or slow down this crucial healing process.
