• The idea that certain functions have certain locations within the brain
• where is the motor area?


  on both hemispheres have a motor cortex which controls the muscles on the opposite side of the body, found in the frontal lobe
• What does the motor neurone do?


  responsible for voluntary movements by sending Sian’s to muscles in the body
• where is the somatosemory?


  parietal lobe
• what is somatosensory responsible for?


  deals with incoming sensory info from skin to produce sensations related to pressure, pain and temp
• where is the visual area?


  oppitcal lobe
• what does the visual area do?


  recieves and processes visual info includes colour, shape, movement
• where is the auditory area?


  temporal lobe
• what is auditory area responsible for?


  analysing and processing acoustic info
• what is primary auditory info involved in?


  processing simple features of sound eg. loudness, tempo, pitch
• what is a case study to support Broca’s area?


  patient tan
• what happened to patient tan

  could not talk properly but could understand language as he had a lesion on left frontal lobe
• what does patient tan support

  that the temporal lobe is responsible for language productivity
• what is wernicke’s area?


  It is responsible for language comprehension
• localisation was developed in the mid 19th century
• who created the equipotentiality theory?


  carl lashely
• what did carl lashely propose?

  challenged localisation
• how did lashley test his theory


  removed 10-15% of cortex in rats as they were learning routes through a maze
• what were the conclusion of lashely?


  There was no area proved to be more important, the process of learning seemed to require every part of the cortex. This suggests that higher cognitive processes such as learning are not localised but are distributed more holistically in the brain
