Fig. 6: Divisive normalization model is not effective at producing categorical response profiles.

A Schematic of normalization circuit model with pooled inhibition and inhibitory feedback55,56. B Schematic of normalization circuit with self-inhibition removed (i.e., with donut-like inhibition introduced). C Plot of CatI computed from the responses of neuron 1 in the normalization model (A; gold data) and in the model lacking self-inhibition (B; blue data), to the standard two-stimulus morphing protocol (as in Fig. 2C); n = 50 model neurons; center lines in the violin plots indicate median values. For comparison, the CatI values for the model from Fig. 2D that contains the donut-like motif (purple), is reproduced here; p = 5.2e-23 (gold vs. purple), p = 8.8e-19 (gold vs. blue), paired two-sided t tests with HBMC correction.
