Abstract : Several general principles are emerging from these studies. First, the functional organization of neural circuits is dynamic, and a single circuit, such as a CPG, can produce several distinct outputs, which in turn, can mediate different behaviors. Second, modulatory transmitters can regulate the functional organization of circuits as well as their responsiveness to inputs. Third, motivational systems can influence behaviors, in part, by acting on motor systems, such as CPGs. Fourth, motor systems possess cellular mechanisms capable of supporting complex forms of neuronal plasticity, which in turn, may contribute to learning and memory. These general principles illustrate that motor behaviors are governed by highly adaptive neural networks and help to explain how systems of nerve cells function to produce and modulate behavior.
