In this video, David Brimacombe draws an analogy between YouTube’s recommendation algorithm and the brain’s predictive processes, especially in the context of post‑concussion syndrome (PCS). He explains that just as YouTube suggests videos based on a user’s past searches, views, and discussions, the brain continuously forecasts future thoughts, actions, and behaviors using prior experiences, beliefs, and thoughts. This predictive function underlies how the body responds after a concussion, influencing recovery trajectories and neuroplastic changes. By understanding the brain’s “algorithm,” viewers can appreciate why certain symptoms persist and how targeted interventions might re‑train these predictive patterns to support PCS recovery.

When you're searching something on YouTube, for example, the algorithm is going to help you find things that you have looked for in the past, have thought about, have talked about, and therefore it feels like that is something that you're going to want to see in the future. The brain acts the same way for your body. It is simply trying to predict what you're going to do, how you're going to think, how you're going to behave based on previous actions, previous beliefs and thoughts.
