lecture 15: temporal and occipital lobes Flashcards
1
Q
occipital lobe function
A
- serves only visual functions
- this makes it very different from other parts of the brain
2
Q
what does damage to the occipital lobe cause
A
- blindness and blindisght
- apperceptive agnosia
3
Q
anatomy of the temporal lobe
A
Lateral surface:
superior, middle and inferior temporal gyrus
1. inferior = IT cortex, visual structure (part of ventral visual stream)
2. middle = visual structure (part of ventral visual stream)
3. superior = auditory functions
Medial surface: medial temporal lobe
medial temporal gyrus = located on the inside, the medial temporal lobes, all the sensory system projects onto it
4
Q
effects of damage to the superior temporal gyrus
A
- auditory region of the brain
- deafness
- wernicke’s aphasia
- auditory agnosia
5
Q
effects of damage to the middle and inferior temporal gyrus
A
- achromatopsia
- akinetopsia
- ventral simultagnosia
- associative agnosia
6
Q
effects of damage to the right medial temporal love
A
- copying is ok
- visual memory impaired
- cortical ventral stream is not damaged, its the stuff on the inside that the central stream projects to which is damaged
7
Q
effects of damage to the left medial temporal lobe
A
- hearing is ok
- verbal memory is impaired
