lecture 5 - brain and cranial nerves part 2 Flashcards
(48 cards)
3 types of areas in cerebral cortex
sensory - perception
motor - execution
association - complex functions
association areas (AAs) (8)
somatosensory AA
visual AA
Facial recognition area
Auditory AA
orbitofrontal cortex
wernickes area
common integrateive area
prefrontal cortex
association areas are concerned with:
complex integrative functions like memory, emotion, reasoning, and more
association areas are connected to each other by:
association tracts
nerve impulses are transmitted from _______ to ______ (in case of doing a complex function)
primary areas to association areas
somatosensory AA location
posterior to somatosensory area
superior to visual areas/cortex
literally think back of the top part of the head
somatosensory AA functions (3)
receives input from primary somatosensory cortex and thalamus
integrates and interprets sensations (shape and texture)
storage of past sensory experiences/memory
eg. pulling keys out of you bag without looking because you remember what they feel like
visual AA location
in occipital lobe
lowest portion of back of the brain
visual AA functions (2)
receives sensory input from primary visual cortex and thalamus
relates visual experiences (object recognition)
functions of parts of the brain
(what to ask myself when asked about these (3))
where does it receive info from
what does it do
example
facial recognition area location
inferior temporal lobe (usually right hemisphere dominant)
facial recognition area functions
receives info from visual association area
stores info about faces
auditory AA location
very top of the temporal lobe
inferior to primary auditory cortex and top parts of cerebrum
posterior to brocas area
auditory AA function
receives info from primary auditory cortex
recognition of sound
orbitofrontal cortex location
lateral part of frontal lobe (says slides, looks more like the bottom from a side view)
orbitofrontal cortex function
receives info from primary olfactory area
identifies odours
wernickes area location
left temporal and parietal areas (kind of broad)
posterior to auditory areas from side view
wernickes aphasia (fluent aphasia)
can speak. but cannot arrange words coherently
lack speech comprehension
wernickes area function
interprets meaning of speech
basically understanding speech
translation of words into thought
common integrative area location
surrounded by somatosensory, visual, and auditory AAs
weird part of the diagram that isnt coloured in the back
common integrative area function
integrates sensory interpretations
forms thoughts bases on sensory input from different areas
transmits signals to parts of the brain for appropriate responses
prefrontal cortex location
biggest “area”
behind frontal bone
prefrontal cortex functions
has many connections with other brain regions
a few things its involved in: personality, intellect, recall, initiative, judgement, reasoning, and lots more
what areas of the cortex are involved in saying a written word? steps
see the word
- primary visual cortex
associate and comprehend the word
- primary visual cortex
- common integrative
- wernickes area
develop a plan for speaking
- brocas area
speak the word
- primary motor
- maybe pre motor as well
