localisation of function in the brain

• Broca + Wernicke: specific area of brain = physical/ psychological function - cortical specialisation

  sone functions controlled by hemispheres
• localisation of function - evaluations

  • S: everyday functions: Peterson et al: Wernickes active listening, Broca’s reading + Buckner & Peterson: semantic + episodic LTM different sides of prefrontal cortex, objective methods = scientific HOWEVER Lashley: removed 10-50% rats cortex leanring maze - no area more important, holistic
  • S: application: Doughtery et al: 44 OCD use cingulgtmy (isolate cingulate gurus), 36w = 30% successful 14% partial - disorders localised
  • W: language not just b + w : Dick + Tremblas: 2% researchers believe it is - brain scans = language across cortex - holistic
• 1. frontal lobe
  2. motor area: voluntary movement - loss of fine movement
  3. parietal lobe
  4. somatosensory area: sensory info from skin
  5. occipital lobe
  6. visual area: cross-wire info from eye - blindness
  7. cerebellum
  8. temporal lobe
  9. Wernicke’s area: language + understanding - Wernicke’s aphasia (nonsense words)
  10. auditory cortex
  11. Brocades area: speech production - Broca’s aphasia (patient Tan)
