Title: How insects see motion: convergence of theory and experiment
Predictions of the Hassenstein-Reichardt Elementary Motion Detector (HR EMD) model have been confirmed in numerous experiments over half a century. Yet, recent connectomics and physiology experiments in the fruit fly revealed major discrepancies with the HR EMD. To address these, we propose a model of motion detection consistent with both old and new experimental results. Moreover, we demonstrate that such motion detector can be learned in a biologically plausible unsupervised setting. More generally, our work opens a door to biologically plausible content invariant object recognition.
