Structure and localisation of function

• Hemispheres

  • Brain is divided into two halves
  • Left and right hemispheres
• Cerebral cortex

  • Top surface of the brain
  • 1-2mm thick
• Frontal lobe

  • Controls thinking and planning
  • Contains the motor area and Broca's area
• Parietal lobe

  • Contains the somatosensory area
• Temporal lobe

  • Contains the auditory area and Wernicke's area
• Occipital lobe

  • Contains the visual area
• Cerebellum

  • Involved in attention and language
  • Supports movement, co-ordination and balance
• Motor area

  • Frontal lobe
  • Left hemisphere- controls movement on right side of the body etc.
• Somatosensory area

  • Parietal lobe
  • Sensitive body parts take up the most space
  • Our face and hands use over half of the area
  • Damage would decrease ability to feel pain and temperature
• Visual area

  • Occipital lobe
  • Eye sends info to the visual area.
  • Damage could lead to blindness
• Auditory area

  • Temporal lobe
  • Processes things we hear
  • Damage can lead to partial or total hearing loss
• Broca's area

  • Frontal lobe
  • Production of speech
  • Damage leads to problems producing speech
• Wernicke's area

  • Temporal lobe
  • Understanding of speech
  • Damage leads to problems understanding speech
