Representational invariance of numerosity via divisive normalization in coarse and fine visual channels

Joonkoo Park, Shimin Hu

The paper tests divisive normalization and Fourier decomposition models for numerosity perception, showing divisive normalization explains neural and behavioral data better.

Neurocomputational principles underlying the number sense

Joonkoo Park, David E. Huber

The paper identifies neurocomputational principles that explain how the brain processes numerosity, showing that center-surround filters, spatial scaling, and divisive normalization account for sensitivity to number and illusions of numerosity.
