DOI: 10.1038/s41593-025-01948-9
Abstract: Many animals navigate using optic flow, detecting rotational image velocity differences between their eyes to adjust direction. Forward locomotion produces strong symmetric translational optic flow that can mask these differences, yet the brain efficiently extracts… read more here.

DOI: 10.1038/s41598-025-03648-7
Abstract: The visual system plays an integral role in maintaining quiet stance. When visual feedback is amplified by increasing the gain of optic flow, individuals develop a tighter control of upright stance. The pattern of optic… read more here.
