... causes them to synapse with the bipolar cells, converting the image of the coffee cup into neural information. In turn the bipolar cells synapse with the ganglion cells, whose axons converge as a bundle to form the optic nerve that carries the information to the brain, where it will diverge to several brain structures. Picture 1 Information from the right and left visual field of each retina are kept separate but travel in parallel towards the brain. At the optic chiasm information from the left visual field is transferred to the right hemisphere and vice versa. From here the ganglion cells are collectively known as the optic tract, most axons of which terminate by synapsing with cells in the lateral geniculate nucleus (LGN) in the thalamus. Axons from the LGN cells then take the information to the primary visual cortex (the occipital cortex), where signals are processed and sent ...
