Avery Andrews (921213) --
Avery, you also asked for a source on the combining of gamma and
alpha reference signals for the Little Man model.
A reference is McMahon, Thomas A.; _Muscles, Reflexes, and
Locomotion_ (Princeton, NJ; Princeton University Press, 1984).
See Chapter 6, Reflexes and Motor Control, subhead Coactivation
of Alpha and Gamma Motor Neurons (p. 148). " ... so the
experiments are in harmony with the idea that both alpha and
gamma motor neurons are excited by higher motor centers at the
same time."
I think that gamma outputs are also involved in autonomic
reflexes, but don't want to get into that kind of detail.
