title: An illusory transformation in a model of optic flow processing.
abstract: We present results from computer simulations of a biologically plausible model of heading detection in the visual motion pathway of higher mammals. These simulations are closely related to a recently discovered visual illusion in optic flow processing in humans. The model reproduces the results described for humans and suggests a possible explanation, namely that humans interpret the illusory stimuli in terms of egomotion. It provides further indication that the visual system makes use of visual information to cope with eye movement effects in dealing with optic flow.
