Self-movement estimation is critical to motor control and navigation; however, the neural circuits that accurately track body motion are poorly understood. This study shows that Drosophila optic-flow-processing neurons receive three distinct locomotor-related signals that are used to encode a quantitative estimate of the fly's walking movements, even in the absence of visual stimuli.
