A neurotrophic model for the co-development of topography and ocular dominance columns in the primary visual cortex has recently been pro- posed. In the present work, we test this model by driving it with the output of a pair of neuronal vision sensors stimulated by disparate mov- ing patterns. We show that the temporal correlations in the spike trains generated by the two sensors elicit the development of refined topogra- phy and ocular dominance columns, even in the presence of significant amounts of spontaneous activity and fixed-pattern noise in the sensors.
