Localization of Function Flashcards
history?
only 70-80 years ago this was accepted/believed
Rene Descartes (early 1600s)
- thought brain functioned as a whole
- recognized 2 sides of the brain
- thought pineal gland was ‘see to the soul’
Gall / Spurzheim (1860s)
- dif of grey/ white matter & communication over corpus callosum
- phrenology - bumps/ depressions relate to brain ability
Broca and Patient Tan

where is the Broca’s Area? (1861)
left frontal lobe
Wernicke (1874)
language area - when damaged has issues comprehending but can speak output.
where is Werenicke’s area?
Left temporal lobe
What did Fritsch & Hitzig discover? (1870)
electricity in one side of brain causes movement in the opposite side.
The lobes are…
multi model except for occipital (only vision)
Damage to the middle/inferior gyrus (temp lobe)…
causes impairments in general cognitions
Damage to the superior temporal gyrus (temp lobe)…
causes deafness, werenicke’s aphasia and auditory agnosia (dif recognizing sounds)
Damage to the right medial temp lobe…
causes visual memory impairment
Damage to the left medial temp lobe… x3
causes verbal memory impairment (hearing/language is good)
anterograde and retrograde amnesia
but these patients also have spared memories and some level of memory retention
The … lobes are all about …
medial temporal lobes … memory
