When we worked on this project, I learned a lot when it came to how the brain works when it goes into a coma. This project was quite similar to the sports project we did previously as it included brain injuries that could also potentially induce a coma. What's quite interesting is that the brain is in a state of very low activity when in a coma, using itself to heal and to help the person recover. When the brain is in a minimal state of activity, it also sets off a hormonal imbalance and induces swelling. There is still so much we don't know about the brain.
