Abstract :
Humans can perceive non-Fourier visual motion, i.e., motion that contains no coherent structure in the distribution of stimulus energy in the spatiotemporal frequency domain. The question that still remains unanswered is whether this non-Fourier motion is analyzed by a separate neural pathway or whether there is a unique pathway that is responsible for both Fourier and non-Fourier motion analysis. We present experimental evidence that strongly supports the separate-pathway hypothesis, and we suggest a possible computational model that can account for the data
