Brain research of the most recent ten years is gathering incredibly precise information about how the human brain learns but also about the incredible variability from one brain to another. That old hunch about each person being unique can be verified by a growing body of research. It also shows how creative the brain is in forming itself and how wildly interconnected it is.
Aikido, it turns out is incredibly good for your brain. Research shows that varying challenge, exercising all parts of the body in coordinated movement, and off-loading working memory with automated stress response strategy is incredibly good at stimulating neuro development and minimizing cortisol exposure (stress hormone that's good to have when you're face to face with a lion, but not so good for extended periods).
The video below is interesting for a lot of reasons but I post it here for how Jill Bolte Taylor speaks about energy and how we perceive our surroundings. Fair warning, the video includes view of a real human brain.
