A Multiple-Level Approach to Motor Pattern Generation
Motor control is studied at multiple levels, e.g., the movement level, the network/circuit level, and the cellular/synaptic/molecular level. The movement level requires the nervous system as well as the muscular system and the structural support system, e.g., skeletal system. The network/circuit level occurs strictly within the central nervous system (CNS). The cellular/synaptic/molecular level has its focus on each individual neurone. Understanding each level illuminates properties at other levels. A levels analysis is used to approach the comparative physiology of motor pattern generation. Specific examples from work on the physiology of turtle scratch reflex are used (Stein, 1989).
