What best explains the disproportionate representation of the fovea in the primary visual cortex?
Added by Sherry S.
Step 1
The fovea is a small central pit in the retina that contains a high density of photoreceptor cells (cones) and is responsible for sharp central vision. Show more…

In the visual cortex the fovea has: A. more representation on the cortex because the fovea has more cells than the periphery. B. less representation than the periphery because the fovea has fewer cells on the retina. C. the same representation on the cortex as the periphery. D. more representation on the cortex than the periphery even though it has fewer cells in the retina.
Supreeta N.
Retinal ganglion cells located at the center of vision in the fovea have the smallest receptive fields in those located in the visual periphery have the largest receptive fields. The large receptive field size of neurons in the visual periphery explains the poor spatial resolution of our vision outside the point of fixation. why is true?
Pahal S.
If several neurons of the visual cortex all respond best when the retina is exposed to horizontal lines of light, then those neurons are probably in the same ________.
