....found throughout the brain. The process of map formation in embryonic and early childhood development has been most extensively studied in the visual system, in projections from the retina to the thalamus and superior colliculus, and in projections from the thalamus to the primary visual cortex [66]. These connections form over long distances, and initially they are highly disordered. After the initial axonal projections form, they sort themselves over time to produce a detailed topographic correspondence between the retinal image and the image in the target structure. This map formation ....
....biological mechanisms that give rise to topographic map formation. A variety of such mechanisms have been studied in the early visual system, including the maintenance of axonal order within the optic tract, positional labelling via chemical markers, and activity dependent synaptic plasticity [66]. The presence of chemical markers guiding map formation has been demonstrated in a variety of experimental preparations [66, 59] Although some early researchers believed these markers might be sufficient to fully specify the final mapping, in practice this does not seem to be true. Evidence for ....

....interest in this type of algorithms comes from the fact that the brain uses many feature maps, such as visual field, somatotopic and tonotopic maps. It is not clear how these maps are formed in the process of development of humans and animals (for a review of neurobiological facts and theories see [6]) Although the real excitement in the neural models of self organization started with the paper of Kohonen in 1982 [2] similar approaches discussing formation of such maps were proposed earlier by Willshaw and von der Malsburg [7] and Amari [8] Since the publication of the original paper by ....

....Many past computational models of the cerebral cortex have concentrated on map formation since this is a prevalent organizational aspect of the mammalian brain. Cortical maps represent similar inputs close to one another in the cortex, and can be divided into topographic maps and feature maps [2, 3]. For topographic maps, similarity of input patterns is measured in terms of their geometric proximity. For feature or computational maps, the similarity measure can represent any functional correspondence of the input patterns. For example, in visual cortex a feature map of stimulus orientation ....
