The correct answer is AExplanationthe six layers of the lateral geniculate ganglion are exquisitely precise in two ways. First, cells in different layers that align (like the numbers in the picture) have receptive fields in the same area of retina. Second, optic nerve fibres from the two eyes are segregated in different layers. Ipsilateral fibres arrive in layers 2, 3, and 5, while contralateral fibres arrive in layers 1, 4, and 6 (no-one knows why).
