Localisation

• Who had a metal rod go through his brain?

  Phineas Gage
• What happened to Gage's personality?

  He suffered a personality change
• What did scientists conclude about Gage's case study?

  The frontal lobe was responsible for regulating the mood
• What are the names of each lobe?

  1. Frontal lobe (front)
  2. Parietal (middle)
  3. Temporal (bottom)
  4. Occipital (back)
• What are the 4 cortexes called?

  1. Motor cortex (back of frontal, movements)
  2. Somatosensory (front of parietal, sensory)
  3. Auditory (temporal, speech)
  4. Visual (occipital, eyes)
• What is the name of the area on the left hemisphere responsible for developing speech?

  Broca's area
• What is the name of the area on the left hemisphere responsible for understanding speech?

  Wernicke's area
• What lobe in the brain will Broca's area and Wernicke's area be located in?

  The temporal lobe
• What kind of study did Broca and Wernicke carry out on their patients?

  Post mortem analysis
• What are the strengths of the theory of localisation of function?

  • Scientific methods
  • Research support - Tulving (LTM)
  • Case study support - Gage
• What are the limitations of the theory of localisation of function?

  • Contradictory research - Lashley's study of rats (brain plasticity)
  • Too simplistic
  • Can't generalise case studies
  • Ethical issues with post mortem
