Retinotopy

As retinotopically we define the properties of the lateral geniculate nucleus (abbreviated CGL - part of the thalamus, divided into 6 layers ), the image information accurately model the visual cortex, so that the topology of retinal activity is retained.

Adjacent fields or excitation patterns in the retina are mapped to neighboring neurons in the brain. For example, looking at a star would just such a pattern of activity, which can be measured for example with PET or magnetic resonance imaging (MRI ) that produce in the brain. The retinotopic property to take three-dimensional and one-one, ie each layer is retinotopically: Every place in the CGL corresponds to a location of the retina, adjacent locations of the retina are adjacent in the CGL.
