“The main reason you can’t move the same way each and every time, such as swinging a golf club, is that your brain can’t plan the swing the same way each time,” says electrical engineering Assistant Professor Krishna Shenoy, whose research includes study of the neural basis of sensorimotor integration and movement control. He, postdoctoral researcher Mark Churchland and electrical engineering doctoral candidate and medical student Afsheen Afshar authored the study.
It’s as if each time the brain tries to solve the problem of planning how to move, it does it anew, Churchland says. Practice and training can help the brain solve the problem more capably, but people and other primates simply aren’t wired for consistency like computers or machines. Instead, people seem to be improvisers by default.
Now I’ve got a new excuse for my lousy golf-playing! Yay, science!
