Descending motor tracts Major sub- divisions	Motor interneuron organization	Brainstem motor nuclei & tracts	Unilateral neglect: peculiarities of facial motor innervation
Muscle coordination for bipedalism	Feed-back and -forward regulation of posture	Coordination & feedback mechanisms	The motor homunculus
Descending motor "nuclei"/areas	Laminar motor cortical projections	Pyramidal motor system	Lateral vs. ventral corticospinal tract
Motor cortical areas	The Babinski sign (plantar retraction vs. flexion)	Corticospinal control of wrists and hands	Arrangement of axons in the pyramdial tracts
Thalamic motor nuclei Inputs/outputs/ function
