Abstract

It is controversial whether head and eye movement information are required to discern locomotor heading from visual motion information1,2,3,4,5. We present a new theory of steering based on active gaze and retinal flow, which demonstrates that future paths could be judged using known properties of visual cortex neurons, without recovering current heading or integrating extra-retinal signals. This theory is consistent with the gaze-sampling behavior promoted in advanced driving instruction.
