The Mixer provides a process involving the storage and retrieval of a myriad of learned motor patterns.
It is those patterns that we somehow need to transmit to another person in order to communicate. Two more processes are involved here.
One process is performed by a transducer--a mechanism that changes energy from one form to another (eg., the speech mechanisms).
The other is performed by the mixer--a memory bank of pre-packaged neural blue prints for most voluntary motor movements. The mixer tells the transducer how to do it.
The Mixer is a process involving the storage and retrieval of motor patterns (like dances). It helps to explain a major mystery... how do we talk?
We do it a lot but we can‰t describe the actual motor sequences. That‰s because they are automatic and activated at a subliminal level from the mixer.
We started learning them when we were born. We built them from simple reflexive (involuntary) movements.
