The design of aircraft cockpits and cars, of road-markings and fire-escape exit signs, of advertisements and warnings can all benefit immensely from a knowledge of what people can see, where they look, and how it all works. In our world of TV and virtual reality, being able to present a person with the information that is needed through their visual sense is vital. Our knowledge of what is used (and what is not used) for a task or a particular percept allows us to compress images so that the minimum amount of information can be sent without the quality of the image being compromised.

Not surprisingly, the M ganglion cells that we discussed earlier send their nerve fibres to the magnocellular layers, and the P ganglion cells to the parvocellular layers. We need two magnocellular layers in each LGN because one receives input from the left eye and one from the right eye. Layer 1 of the left LGN receives its input from the right eye and is known as a contralateral layer, whereas layer 2 of the left LGN receives its input from the left eye and is known as an ipsilateral layer. When we come to the parvocellular layers, layer 3 is an ipsilateral layer and layer 4 is a contralateral layer.
