So much of our brain real estate is devoted to movement that it's been hypothesized for more than a half century, but especially in recent years as we've learned more about the function of the brain at a really detailed circuit level that the relationship between the brain and body and the maintenance and perhaps even the improvement of neural circuitry in the brain depends on our body movements and the signal from the body that our brain is still moving. the fact that osteocalin is released from bone and in particular can be released in response to loadbearing exercise. So this would be running again weightlifting hasn't been tested directly but one would imagine anything that involves jumping and landing or weight lifting or body uh body weight movements and things of that sort. That's a signal to release osteocalin and we know that signal occurs that is directly reflective of the fact that the body was moving and moving in particular ways.
