  • Controls high - level cognitive functions e.g. thinking and planning.
  • Contains the motor cortex which controls voluntary movements on the opposite side of the body.
• Parietal lobe

  • Contains somatosensory cortex.
  • Processes sensory information from the skin e.g. temperature and pressure.
• Temporal lobe

  • Contains auditory cortex.
  • Deals with sound info (mainly from opposite ear) e.g. volume and pitch.
  • Has a role in understanding language.
• Occipital lobe

  • Located at the back of the brain.
  • Each lobe contains visual cortex.
  • Deals with visual information.
  • Everything is processed by the left visual cortex first.
