I thought a while about the topoic of central pattern generation and the idea of having the motor symphony stored somehow in the brain or body and the implications of this idea. I'm not sure how that would necessarily change behavior, but it raises many questions in my mind about how the patterns are stored and when we develop the tools or hardware to store certain types of behavior. Does the idea of CPG mean that we basically have a blueprint of reactions to set patterns of received stimuli? Also, is the idea of CPG related to the controversy of whether we are pre-wired for certain behaviors or not?

One implication of CPG is that, again, how much of our behavior do we actually have control over? If a stimulus sets off a stored pattern of behavior that was imprinted in our brain by the environment, where does that leave free-will again (hey, maybe that's how we can explain phobia's), but then we talked about the idea of getting outputs without the necessity of an input.

Interesting/appropriate thoughts/questions. Probably due have "blueprints", but not sure its appropriate to call them "reactions". Remember that normally they are modified by sensory input at the time (we got rid of that only to sure their existence). Pre-wired? More or less for some things, less or more for others, since CPG's can relate to learned behaviors. Free-will? Hmmmm. We're not quite there yet (but will get there). Suspect it will turn out that CPG's help with rather than hindering that argument. The more one has to work with, the greater the range of possible behaviors; hence more choice? PG
