Two different schemes for speed discrimination by units in the macaque area MT, logarithmic coding and linear coding. Ten units are shown with constant bandwidth and with sensitivities distributing across a range of speeds. In the bottom panels, for logarithmic coding note the increase in discrimination threshold with the speed of motion, as well as the constant Weber fraction. See the article by Nover et al. for details in favor of logarithmic coding.
