22. As a movement becomes more practiced, it is represented more
extensively in primary motor cortex
23. Summary
Primary Motor Cortex:
– Codes force and direction of movement
– Spinal motor neuron are directly under control for precise
movement.
Dorsal Premotor Cortex
– Movement related neuron encodes sensorimotor
transformation for visual and sensory cue
– Fire before movement
Ventral Premotor Cortex
– Encodes learned motor act fire before movement
All cortical neurons are adaptable and plastic
