Fig. 5. Correspondence between selective numerosity tuning curves in layer IPS of nDNN model and IPS subdivision of parietal cortex in monkeys.

B Normalized tuning curves in our nDNN model (Fig. 4A, B) averaged across all numerosities showing tuning curves up to a distance of 4 units from the preferred numerosity, compared to tuning curves in monkeys. Numerosity tuning curves in layer IPS of the nDNN were similar to the those reported in the IPS of monkeys. Layer IPS units showed high-levels of similarity only after training. V1, V2, and V3 units did not show similarity with neuronal recordings either prior to after training.
