<P> Once the image is spatially encoded by the centre -- surround structures , the signal is sent out along the optic nerve ( via the axons of the ganglion cells ) through the optic chiasm to the LGN ( lateral geniculate nucleus ) . The exact function of the LGN is unknown at this time . The output of the LGN is then sent to the back of the brain . Specifically , the output of the LGN `` radiates '' out to the V1 primary visual cortex . </P>
