The lateral geniculate nuclei (LGN)are 6-layer structures in each hemisphere, which receive input from the retina from the ipsilateral and contralateral eyes. What is true of the layer distribution of the LGN regarding how they receive inputs from the eyes? layers 1, 4 and 6 from contralateral eye layers 4,5 and 6 from ipsilateral eye layers 2,3 and 5 from ipsilateral eye a) and c)
