The model is based on a temporal extension of the Self-Organizing Map where neurons act as leaky integrators. The map is trained with moving Gaussian inputs, and it develops a retinotopic map with orientation columns that divide into areas of opposite direction selectivity, as found in the visual cortex. date: 1999 date_type: published pagerange: 251-256 refereed: TRUE citation: Farkas, Igor and Miikkulainen, Risto (1999) Modeling the self-organization of directional selectivity in the primary visual cortex.
