Fig. 6. Divergences between the brain and the SOM.

(A) Left: Three-way preference map in the OTC among big objects, all animals, and small objects; adapted from (9). Right: Four-way preference map in the SOM among big objects, small objects, big animals, and small animals using the same stimuli as used in (9). (B) Category selectivity maps computed using the d′ measures with each of the eight categories from the stimulus set used in (59) serving as the target, and the other seven categories serving as the nontarget images. These plots are organized by an approximate estimate of their nonuniformity, calculated with a js-distance score reflecting on how strongly the distribution of selectivity scores deviates from a distribution of uniform selectivity.
