Week 2: Unraveling the Mysteries of Concussions Part 1

Mar 18, 2021

Hello everyone! Welcome to the second week of my senior project journey. What happens inside our brain while undergoing a major hit simultaneously? It is important to focus on the movements of our brain and our skull during a major hit. This key information will also give us more hints on the healing process that takes place during and after a concussion.

It is commonly known that when a major hit is delivered to the head, the skull moves while the brain moves sublty. The skull moves fast while the brain stays where it is at for the most part because of inertia. There are two types of ways the brain and the skull can move. One way is linear acceleration which results in a more focal injury. The other is rotational acceleration which results in diffuse injury. Both of these movements have to happen in order to create a concussion.

Our brain moves like jello. When we picture jello in our minds, it is something that moves back and forth at every instant. This motion is similar to the brain’s motion when impacted. The brain will move sublty until it returns to rest. When our brain and skull move this causes the neurons inside to stretch and break. Injuries to neurons causes chemicals to leak inside of them. This will destabilize the neurons and make it harder for them to execute the jobs. The mitochondria also gets damaged when chemicals start to leak. This will lead to decreased energy. This will also lead to headaches and nausea. Overall, this week was informative. I learned the basics and the foundations for more adnavced research. Next week my focus will be on the healing process.

    Very interesting Milan! Excellent job providing a visual explanation as to how the brain and skull move about to cause a concussion. It’s interesting because I only tend to associate nausea and headaches when it comes to concussions. However, hearing all the biological factors that induce the common symptoms that ensue head injuries was fascinating to read. I am excited to see what you learn in the coming weeks. Keep up the good work!

      Thanks Sean! I also had a similar mindset as you. As I have researched more, I have learned there are many more phases and factors involved.

    Hi Milan,

    Great example of how our brains are affected by a concussion! I have wondered about the varied symptoms with concussions and what specific injuries caused things like inability to focus versus lethargy. I appreciated the detail of neuron damage versus mitochondrial damage. Looking forward to learning more as you explore recovery from concussions.

    I always thought of concussions as injuries to the skull rather than the brain. Its interesting that the brain can be injured in such a way just from hitting it hard enough.
