Localisation Of Function AO1

• Localization of function


  Different areas of the brain are responsible for specific behaviours
• Language


  • Thought to be lateralised as well as localised
  • Broca's area (speech production) in the left frontal lobe
  • Wernicke's area (speech comprehension) in the left temporal lobe
• Damage to Broca's or Wernicke's area

  Could develop aphasia
• Broca's aphasia


  Problems with speech (slow, lacking in fancy)
• Wernicke's aphasia


  Difficulty understanding speech, can result in using neologisms (nonsense words)
• Motor cortex


  • In the frontal lobe
  • Contralateral - controls voluntary movement on the opposite side of the body
• Somatosensory cortex


  • In the parietal lobe
  • Receives messages regarding sensation from the opposite side of the body
• Visual cortex


  • In the occipital lobe
  • Has both contralateral and ipsilateral connections
  • The left visual field of both eyes goes to the right hemisphere and vice versa
• Auditory cortex


  • In the temporal lobe
  • Processes information e.g. pitch/volume
  • Has both contralateral and ipsilateral connections
