localisation of function

• localisation 


  the theory that different areas of the brain are responsible for different behaviours, processes or activities
• brain divided in 2


  left+ right hemisphere
• lateralisation 


  left side body controlled by right hemisphere, right side of body controlled by left hemisphere
• strength: brain scan evidence

  • support- functions are localised
  • Peterson et al.- brain scans- demonstrate Wenicke's area was active during listening task + Broca's area for reading
  • measures activity- scientific evidence
• strength: neurosurgical evidence 


  • practice of surgically removing or destroying areas
  • Walter Freeman- lobotom
• strength: case study evidence
