Edgar Erwin, Klaus Obermayer, and Klaus Schulten. A critical comparison of models for orientation and ocular dominance columns in the striate cortex.

ERWI95 More than ten of the most prominent models for the structure and for the activity dependent formation of orientation and ocular dominance columns in the striate cortex have been evaluated. We implemented those models on parallel machines, we extensively explored parameter space, and we quantitatively compared model predictions with experimental data which were recorded optically from macaque striate cortex. In our contribution we present a summary of our results to date. Briefly, we find, (i) that - despite apparent differences - many models are based on similar principles and, consequently, make similar predictions. (ii) that certain "pattern models" as well as the developmental "correlation-based learning" models disagree with the experimental data, and (iii) that - of all the models we have investigated so far - "competitive Hebbian" models and the recent model of Swindale provide the best match with the experiment.
