• Hierarchical: 3 major types
– Reflexes       Spinal cord circuits
– Postural adjustments     Spinal & Brain stem
– Voluntary movements   Spinal cord, Brain
           stem, & cortex
Postural adjustments & voluntary movements
depend more on cerebellar and basal ganglia
function than reflexes
Dual purpose: 1) upcoming lectures;
2) context for motor pathways
