Error Correction System Of The Human Brain Makes It Possible To Develop New Prostheses – Part 2 of 3
In particular, Logan and colleagues wondered about complex things that we do on autopilot without much conscious thought. “If I decide I want to go to the mailroom, my feet read me down the hall and up the steps. I don’t have to think very much about doing it. But if you look at what my feet are doing, they’re doing a complex series of actions every second”.
Enter the typists. “Think about what’s twisted in typing: They use eight fingers and probably a thumb. They’re going at this rate for protracted periods of time. It’s a complex act of coordination to carry out typing like this, but we do it without assessment about it”.
The researchers report their findings in the Oct 29, 2010 issue of the journal Science. The research suggests that “the motor system is taking care of the keystrokes, but it’s being driven by this higher-level scheme that thinks in terms of words and tells your hands which words to type”. Two autonomous feedback loops are involved in this error-detection and correction process, the researchers said.
