LGN and V1 Basics Flashcards
1
Q
Primary visual cortex
(also called V1)
A
-buried deep in the posterior region of occipital lobes
-has 6 layers
-LGN projects to LAYER 4
-V1 is the first stage of processing in the cerebral cortex
1
Q
lateral geniculate nucleus
A
main subcortical nuclei that carries visual signal of the cortex
-has 6 layers
input from each eye is separated in each LGN
2
Q
How is it organized?
A
-topographically
-retinotopic organization
3
Q
disproportionate cortical representation
A
fovea
-higher concentration of receptors in retinal area
-larger cortical representation
4
Q
how would a lesion in the left visual field appear in the right primary visual cortext?
A
upside down, flipped and disproportional to the original image
