localisation of function

Cards (10)

  • certain functions are fixed in particular regions of the brain
  • visual centres
    located at back of brain - occipital lobe receives and processes visual info
    info from right visual field is processed in left hemisphere
    info from left visual field is processed in right hemisphere
  • auditory centres
    located in temporal lobe - analyses acoustic info
    info from left ear goes to right hemisphere
    info from right ear goes to left hemisphere
  • motor cortex
    located in frontal lobe
    responsible for voluntary movements by sending signals to the muscles in body
    regions logically arranged
  • somatosensory cortex

    located in parietal lobe
    detects sensory events
  • brocas area
    language production
    cognitive tasks
    located in frontal lobe of left hemisphere
    brocas patients could understand language but couldn’t speak
  • wernicke’s area
    language comprehension
    located in left temporal lobe
    wernicke’s patients could speak but couldn’t understand language
  • ✔️fMRI scans are used to measure the activity of the brain in response to a stimulus - whilst performing a certain task, some areas of brain have an increased level of oxygen and other regions become deoxygenated
  • ✔️phineas gage study - part of brain damaged due to pole going up his eye, through his brain and out his head - personality completely changed after
  • X case studies - unrepresentative and ungeneralisable - can’t rely on it too much
