Why bother study the motor pathways?
		• Anatomical substrates: How it works • Multiple parallel paths & diversity of spinal connections – Damage to 1° motor cortex and pre-motor cortex projections recover some lost functions – Damage to cortex and brain stem paths recover some lost functions – With spinal cord injury. loss of monosynaptic connections and alternate paths via segmental and intersegmental interneurons can recover some lost functions
