localisation of function

• localisation - functions such as movement speech and memory are performed in distinct areas of the brain
• motor cortex - frontal cortex - plans and carries out voluntary movements - damage can lead to paralysis
• somatosensory cortex -run alongside fold in brain - detects sensations - can lead to loss of sensation if damage
• occipital lobe - smallest lobe - brains visual processing center - back of the brain - recieves info from each hemisphere - damage can lead to loss of vision
• brocas area - frontal lobe - discovered after case study and post mortem - responsible for speech production - case study tan - lead to brocas asphasia
• auditory cortex - located at top of temporal lobe - damage can lead to deafness
• wernickes area - temporal lobe - produce but not understand speech - wenickles asphasia
• global asphasia - damage to brocas and wernickes area
• functionally specialised brain areas - motor - somatosenssory - visual - auditory - both sides of brian
• contralateral - hemisphere controls oppositite side of body
• eval - support from broca and wernickles
• pro - modern brain scanning techniques support this
• lashley - research evidence against localisation - mice ran a maze - had brain parts removed and re ran
