localisation of the brain Flashcards
frontal lobe
motor area
personality and descions
responsible for voluntary movement by sending signals to muscles in body
parietal lobe
somatosensory
receives sensory info from skin to produce sensations
related to pressure and pain and temp
different parts receive messages from different places
temporal lobe
auditory area
analysing and processing acoustic infomation
involved processing simple features of sound including loudness, temp, pitch
occipital lobe
visual
receives and processes visual information
contains different parts that process different types of information including: colour, shape and movement
brocas area
responsible for speech production
left frontal lobe
patient tan case
brocas area
could only say the word tan
postmortem revealed lesion in left frontal lobe
supporting evidence for localisation
wernickes area
responsible for language comprehension
left temporal lobe
wernickes case study
couldnt put words together properly, understand what people was saying but couldnt answer out loud properly
postmortem found damage to left temporal brain
supporting evidence shoes specific parts of the brain have specific functions
weakness
biological reductionism
reduces complex human behaviour and cognitive processes to one specific region of the brian. argues a more thorough understanding of the brain is needed to understand complex cognitive processes like language
localisation
each specific lobe in the brain has its own meaning
evaluation
use patient tan and wernicke for support
dronkers et all
falseafilable
mri scans- objectivity
doesnt take account of individual differences
dronkers et all (against)
conducted a mri scan on tans brain. leison found in brocas area but also found evidence to show other areas have contributed to the failure of speach production
