With advanced optical imaging techniques [5, 6] it is now possible to monitor the activity of neural populations synchronously with a high spatial resolution. This kind of measurement should finally enable a comparison of experiment and mathematical theory in quantitative detail. In this contribution we start to outline the respective contributions of linear and nonlinear dynamics in the development of visual cortical maps, the different timescales, on which these qualitatively distinct processes take place and how their effects might be accessed experimentally in a quantitative fashion."],["dc.identifier.doi","10.1007/978-1-4615-2235-5_59"],["dc.identifier.gro","3151867"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8698"],["dc.language.iso","en"],["dc.notes.status","public"],["dc.notes.submitter","chake"],["dc.publisher","Springer"],["dc.publisher.place","Boston, MA"],["dc.relation.isbn","978-1-4613-5940-1"],["dc.relation.ispartof","The Neurobiology of Computation"],["dc.title","Linear and Nonlinear Dynamics in the Development of Orientation Preference Maps"],["dc.type","book_chapter"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

In cat, additional geometric anomalies known as islands or type-II organization have been observed [2, 3]. The ontogenesis of these visual representations is studied in a model of activity-dependent self-organizing maps. The field discontinuities and islands are explained by the occurrence of dynamical instabilities depending on the geometry of the cortical area. A comparison with neurophysiological data from a variety of species shows that field discontinuities indeed occur in areas of elongated shape only. The approach also explains the large degree of interindividual variability observed in cats by the coexistence of several solutions of the model. These results demonstrate that field discontinuities and islands can be explained by the same developmental mechanism."],["dc.identifier.doi","10.1007/978-1-4615-3254-5_61"],["dc.identifier.gro","3151868"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8699"],["dc.language.iso","en"],["dc.notes.status","public"],["dc.notes.submitter","chake"],["dc.publisher","Springer"],["dc.publisher.place","Boston, MA"],["dc.relation.isbn","978-1-4613-6431-3"],["dc.relation.ispartof","Computation and Neural Systems"],["dc.title","Field Discontinuities and Islands in a Model of Cortical Map Formation"],["dc.type","book_chapter"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]
