Nervous system architecture: from the output side II

Welcome to the on-line forum associated with the Biology 202 at Bryn Mawr College. Its a way to keep conversations going between course meetings, and to do so in a way that makes our conversations available to other who may in turn have interesting thoughts to contribute to them. You're welcome to post here any thoughts that have arisen during the course this week (and to respond to thoughts others have posted).

We've begun to move on from the building blocks of the nervous system to its architecture, as seen from the motor side:  distributed systems (no conductor), influences of the nervous system itself on interpretation of input (corollary discharge), reafferent signals and loopiness (exploration and "purpose"), the I-function as an inhibitor.    How do  these things help make sense of behavior?  What new questions do they in turn raise?
