Document Summary

Sensorimotor control: objective: describe the various behavioral components of sensorimotor control structures of the descending neural pathways ( from brain to spinal cord), their functions, and mechanisms underlying reflexes and voluntary control of movements. Introduction, categories of movement, basic concepts: motor units, proprioception, and spinal circuits, brain mechanisms and movement, effects of stroke, introduction, categories of movement, basic concepts. Proprioception: somatosensory signal determining where/position of body parts needed for all movement. Imaging vs. actually performing an action: categories of movement, voluntary movements (under volitional control, reflexes (automatic, rhythmic motor patterns (involves repeating patterns of movement), associated with the central pattern generator. 3 basic concepts: fine motor control requires proprioception and efferent copy = command sent out. Proprioception and efferent copy are used for adjusting ongoing movements in order to reduce error and smooth out reference: the case of g. o. Shifting control to lower levels: motor programs.
