Localisation of Function in the Brain and Hemispheric Laterilisation Flashcards
what was believed pre 19th century?
took a holistic approach saying that all parts of the brain were involved in processing thoughts and actions
what 2 psychologists are important in localisation of function?
Wernicke
Broca
what did Broca and Wernicke say?
specific parts of the brain are involved in specific psychological/physiological function
what can localisation of function also be referred to as?
cortical specialisation
Wernicke and Broca said if a certain area of the brain is damaged then…
the brain wouldn’t perform function
where is Wernicke’s area?
left temporal lobe
what is Wernicke’s area associated with?
language processing and comprehending information
can people with Wernicke’s aphasia understand what someone is saying?
no
can people with Wernicke’s aphasia respond?
yes but it is meaningless
where is Broca’ s area?
left frontal lobe
what case study do you refer to in Broca’s area?
LeBorgne, also known as Tan
explain the case study of Tan
understood spoken language, but couldn’t produce coherent words, could respond with left hand e.g. thumbs up/down
what is Broca’s area associated with?
speech production
what does Broca’s aphasia lead to?
slow, inarticulate and incomplete speech
what is the frontal lobe responsible for?
the motor area
what does the frontal lobe control?
voluntary movement in opposite side
what does damage to the frontal lobe do?
it means loss over fine movements e.g. facial movements, speech control etc.
what is the parietal lobe responsible for?
somatosensory area
what is the parietal lobe and frontal lobe separated by?
central sulcus channel
parietal lobe get ____ info from ____…
sensory information from skin e.g. pressure, touch and heat
what does the amount of area in parietal lobe amount to?
it amounts to the amount of receptors e.g. face takes up half of parietal lobe
what is the occipital lobe responsible for?
visual area
where is the occipital lobe located?
Back of the brain
if there is damage to the left hemisphere’s occipital lobe, what can be affected?
Blurred vision, trouble standing, and blindness
