Motor Cortex

• Multiple motor systems control body movements

  • Walking, talking, postural, arm and finger movements

• Primary motor cortex is located on the precentral gyrus

  • Motor cortex is somatotopically organized (motor homunculus)
  • Motor cortex communicates with
    • Premotor cortex
    • Supplemental motor area
    • Frontal association cortex
    • Primary somatosensory cortex
  • Planning of movements involves the premotor association cortex and the supplemental motor area which influence the primary motor cortex
