WebLiterature on foveal vs peripheral vision?? Hi everyone, I was wondering where I could find (accessible) research on foveal vs peripheral vision, more specifically in regards to what … Webcells is far greater in the visual periphery than in foveal or parafoveal vision, leading to a loss of visual resolution (i.e., higher spatial frequencies) in the periphery. Con-sequently, both the lateral geniculate nucleus (LGN) and the primary visual cortex (V1) devote many more cells to processing central vision than to peripheral vision, a
The loss of peripheral vision while retaining central vision is known as tunnel vision, and the loss of central vision while retaining peripheral vision is known as central scotoma . Peripheral vision is weak in humans, especially at distinguishing detail, color, and shape. This is because the density of receptor and ganglion cells in the retina i…
