On the Shifter Hyposthesis for the Elimination of Motion Blur
Moving objects may stimulate many retinal photoreceptors within the integration time of the receptors without motion blur being experienced. Anderson and vanEssen (1987) suggested that the neuronal representation of retinal images is shifted on its way to the cortex, in an opposite direction t...

| description | Moving objects may stimulate many retinal photoreceptors within the integration time of the receptors without motion blur being experienced. Anderson and vanEssen (1987) suggested that the neuronal representation of retinal images is shifted on its way to the cortex, in an opposite direction to the motion. Thus, the cortical representation of objects would be stationary. I have measured thresholds for two vernier stimuli, moving simultaneously into opposite directions over identical positions. Motion blur for these stimuli is not stronger than with a single moving stimulus, and thresholds can be below a photoreceptor diameter. This result cannot be easily reconciled with the hypothesis of Tshifter circuitsU. |
