Document Summary

Objective: be able to describe the various behavioral components of sensorimotor control, structures of the descending neural pathways (from brain to spinal cord) and their functions, and mechanisms underlying reflexes and voluntary control of movements. Lecture outline: introduction, categories of movements, and basic concepts. Effects of stroke: introduction, categories of movements, and basic concepts. A common misconception is that sensorimotor control is just about muscle control. However, movement is not just about connections between a stimulus and muscle contraction. Conscious action relies on cognitive processes and constant sensory feedback; it is highly adaptive and proactive. Movement and sensory control is about the overall plan. Sensory motor control does not have to do with muscle has a lot to do with the brain. What are the different components required for generating complex movements: Volition, coordination of many muscle groups, postural adjustments, proprioception, sensory signal processing, adaptability, etc.
