pre-motor and supplemental motor cortices

pre-motor and supplemental motor cortices

planned movement/sequences

pre-motor cortex

(6 - inferior) needs sensory input; activates proximal muscles

supplemental motor cortex

(6 - superior) mental rehearsal, learned sequences, activates distal muscles; no descending pathways
