Abstract

Basis functions Central pattern generators Degrees of freedom problem Force fields Internal models Kinematic submovements Modularity Motor pools Motor primitives Premotor drives Reflexes Segmental motor system Spinal cord Synergies Trajectory formation
The spinal cord of tetrapods manages the complexity of movement by organizing muscle recruitment in a modular fashion. Reflex and locomotor behaviors may be composed from a collection of simpler building blocks, or spinal motor primitives, recruited by the pattern generator systems for these behaviors. These may allow straightforward construction of motion, interaction, and control and may ‘bootstrap’ early motor learning during development.
