Principles of command and control for neuroprostheses

摘要: Abstract Neuroprostheses (NPs) are systems for the substitution or augmentation of missing control sensory signals in humans with disability. The NP sends to neural affecting both afferent and efferent pathways. This artificially generated activity directly activates motor systems, triggers spinal reflexes, changes overall transmission cortical structures, thereby modifying excitability. We suggest that artificial command NPs must mimic hierarchical hybrid organization is characteristic humans. means following: (1) at top level user by discrete signals, (2) middle uses a finite state model system spatial time coordination between actuators, (3) bottom considers musculo-skeletal properties actuation implements continuous model, (4) feedback combine depending on where sent to. methods discussed this chapter apply assist goal-oriented movements (e.g., reaching, grasping, standing up, sitting down) and/or cyclic walking).
