A Model of Adaptive Development of Complex Cortical Cells

We present in this paper some initial results from a model of activity-dependent development of complex cortical cell receptive fields. We hypothesize that, in general, cortical layers II and III may be the locus of classical conditioning, and that complex cells in primary visual cortex may develop through conditioning to low-level visual information. We demonstrate that an unsupervised time-derivative adaptation rule can yield characteristics of complex cell fields, in both a simplified abstract model and a more detailed, large-scale model with 57,000 cells.
