what Broadmann area(s) is/are found in the precentral gyrus?
|
4 and 6
|
|
|
1. what does Broadmann area 4 do?
2. Where is it? |
1. (also called M1)
-simple contralateral motion 2. Precentral gyrus |
|
|
1. What does Broadmann area 6 do?
2. Where is it? |
1. stimulus and complex movements
-supplementary motor in medial aspect controls muscle tone, coordination, initializing motion (M2) -Precentral gyrus |
|
|
What Broadmann area is in the middle frontal gyrus?
What does it do? |
8
coordinates eye movement to the contralateral direction. REM. |
|
|
Where is Broadmann area 8?
What does it do? Injury causes what? |
-middle frontal gyrus
-contralateral eye movement and REM -both eyes move towards the injured side |
|
|
Which areas are in the prefrontal cortex?
|
9, 10, 11, 12
|
|
|
Which Brodmann area(s) is/are the broca area?
Where is it? what is it? |
44, 45
-inferior frontal gyrus, opercular and triangular parts -motor speech |
|
|
Where are Broadmann areas 44, 45 located?
What do they do? what does lesion cause? |
-opercular and triangular parts of inferior frontal gyrus
-broca area for motor speech -motor aphasia- understanding but no writing/speaking |
|
|
What broadmann area is in the opercular/triangular parts of the inferior frontal gyrus?
|
Broca's area- 44,45
|
|
|
What Brodmann areas are in the superior temporal gyrus?
|
HESCHL gyruses: 41,42
|
|
|
where are brodmann areas 41, 42 and what do they do?
|
in the superior temporal gyrus (Heschl gyruses)
-analyzing sound: where it comes from and distance |
|
|
What Brodmann area is the Wernicke area?
What does it do? Where is it? |
22
-speech recognition, and interpretation of words -superior temporal and middle temporal gyrus (p.s. damaged in Alzheimers) |
|
|
In what hemisphere is the Wernicke area (22) more dominant?
|
left hemisphere
|
|
|
Why is it important that Wernicke's area (22) overlaps 21?
|
Broadman 21, the middle temporal gyrus, is responsible for visual recognition.
Damage leads to visual agnosia. |
|
|
Which Brodmann area is in the middle of the inferior temporal gyrus?
What does it do? |
Brodmann area 20.
-processes complex visual input, like faces |
|
|
What is Brodmann area 20 and where is it?
Lesion? |
-it's in the inferior temporal gyrus and it processes complex visual input.
-visual agnosia, no face recognition, maybe long term memory, attention disorder |
|
|
what do 20, 21, 22 have in common? And what does a temporal lobe lesion do?
|
They involve memory, speech, emtions. So injury can lead to problems expressing emotion.
|
|
|
Which Brodmann areas are in the post-central gyrus and what do they do?
|
3, 1, 2. Somatosensory cortex for touch, temperature, and pain.
|
|
|
Which Brodmann areas are the senosry cortex?
Where are they? Lesion? |
3, 1, 2, in the postcentral gyrus.
Lesion leads to sensation problems, temperature insensitivity, inability to find body parts. |
|
|
Which Broadmann areas are on the superior parietal lobule?
What do they do? |
5, 7. Interpretation of senses and movement planning (ie catching a ball)
|
|
|
Where are areas 5, 7?
What do they do? Lesion? |
Superior parietal lobes, planning movements, trouble knowing what to do with objects or recognize it by touch. Or neglect of opposite sides of objects. (Left world syndrome if non-dominant hemisphere is damaged)
|
|
|
Which Brodmann areas are in the angular and supramarginal gryruses?
Lesion causes? |
39, 40
Injury to dominant one --> Gerstman syndrome (finger agnosis, agraphia, acalculia, left-right disorientation) |
|
|
What is Gerstman syndrome?
|
Damage to the angular gyrus (Broadman 39)
Leads to finger agnosis, agraphia, acalculia, right left disorientation |
|
|
Where are the visual areas? What are they?
|
Occipital lobe!, 17, 18, 19
|
|
|
Which broadmann area is the primary visual area?
Lesion? |
Area 17.
Lesion leads to homonymous hemianopsia. |
|
|
Which Broadmann areas are the secondary visual areas?
Lesion? |
18,19
visual memory problems- trouble identifying what they see. |
|
|
What does it link:
Superior longitudinal fasciculus |
frontal and occipital lobes
|
|
|
What does it link?
inferior longitudinal fasciculus |
occipital and temporal lobes
|
|
|
what does it link?
arcuate fasciculus |
frontal lobe with occipitotemporal cortex
|
|
|
What does it link?
uncinate fasciculus |
frontal and anterior temporal lobes
|
|
|
what does it link?
anterior commissure |
Anterior temporal lobes
olfactory tracts |
|
|
Where are they?
Posterior commissue and habenular commissure |
right in front of pineal gland
|
|
|
what system are the superior colliculi part of?
|
visual system
|
|
|
what system are the inferior colliculi part of?
|
auditory system
|
|
|
what nerve emerges from just below the inferior colliculus?
|
trochlear nerve (IV)
|
