In a recent paper, Tkacik et al. (Phys. Rev. Lett. 110: 058104, 2013), proposed a new measure of the neural-based distance between stimuli. We comment on this work in the general context of neural coding, dicuss how to test the alididty of the proposed model, and speculate on interesting applications.
