Re: Concerning feedback in the human body...

The idea originates at MIT circa 1942:

"Thus Wiener and Bigelow discovered the closed loop of information necessary to correct any action--the negative feedback loop--and they generalised this discovery in terms of the human organism....Their purpose was to approach the study of living organisms from the viewpoint of a servomechanisms engineer and, conversely, to consider servomechanisms with the experience of the physiologist." http://pespmc1.vub.ac.be/CYBSHIST.html

"The beginner has to find each note tentatively, using a clumsy series of feedback controlled iterations to move the fingers, while the skilled player instead uses muscle entrainment to play each note confidently."

Muscle entrainment is an enhancement of the overall feedback process. The skilled player uses *conscious feedback* to make micro-corrections in real-time while depending on his muscle memory to walk (less consciously) through the notes. When a tennis player returns a serve standing on one leg there is more to it than muscle memory. When a golfer corrects his forearm rotation in mid-release there is more to it than muscle memory. When a cat swats an escaping bird in mid-flight there is more to it than muscle memory.

Here is a quote from "Consciousness as a Feedback Interface":

http://www.innerworlds.50megs.com/consciousness.htm

"The speeds at which neuromagnetic signals are propagated, together with their capacity to recruit/alter multiple modalities suggests that the underlying mechanism has been selected to make instant choices on which specific portions to recruit in order to facilitate the behaviors acted out of the State, and to do so quickly....When it comes to response to threats, or sighting prey, the evolutionary advantages are obvious."
