i-Perception, 2021 The concept of optic flow, a global pattern of visual motion that is both caused by and signals self-motion, is canonically ascribed to James Gibson's 1950 book “ The Perception of the Visual World.

Circuit Organization Underlying Optic Flow Processing in Zebrafish
Frontiers in Neural Circuits, 2021 Animals’ self-motion generates a drifting movement of the visual scene in the entire field of view called optic flow. Animals use the sensation of optic flow to estimate their own movements and accordingly adjust their body posture and position and ...

Examining the contributions of radial and lamellar optic flow gain to quiet stance [PDF]
Scientific ReportsThe 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.

Optic Flow Simulating Self-Motion Does Not Modulate the Hoffmann Reflex in the Soleus During Upright Standing in Healthy Young Adults [PDF]
Brain SciencesBackground/Objectives: Visual motion is a powerful contributor to postural control, yet its influence on modulation of the Ia afferent pathway remains to be confirmed. This study investigated whether optic-flow simulating self-motion modulates the soleus

The effect of vection on the use of optic flow cues [PDF]
Royal Society Open ScienceWhen we move objects move past us in a relative pattern of motion referred to as optic flow. Modulations in optic flow can impact both our perception of self-motion (e.g.

Virtual reality—enhanced walking in people post-stroke: effect of optic flow speed and level of immersion on the gait biomechanics [PDF]
Journal of NeuroEngineering and Rehabilitation, 2023 Background Optic flow—the apparent visual motion experienced while moving—is absent during treadmill walking. With virtual reality (VR), optic flow can be controlled to mediate alterations in human walking.

Optic flow density modulates corner-cutting in a virtual steering task for younger and older adults [PDF]
Scientific ReportsThere is a critical need to understand how aging visual systems contribute to age-related increases in vehicle accidents. We investigated the potential contribution of age-related detriments in steering based on optic flow, a source of information known ...

ReLU, Sparseness, and the Encoding of Optic Flow in Neural Networks [PDF]
SensorsAccurate self-motion estimation is critical for various navigational tasks in mobile robotics. Optic flow provides a means to estimate self-motion using a camera sensor and is particularly valuable in GPS- and radio-denied environments. The present study

The need for speed: global optic flow speed influences steering [PDF]
Royal Society Open Science, 2016 How do animals follow demarcated paths? Different species are sensitive to optic flow and one control solution is to maintain the balance of flow symmetry across visual fields; however, it is unclear whether animals are sensitive to changes in ...

Accuracy optimized neural networks do not effectively model optic flow tuning in brain area MSTd [PDF]
Frontiers in NeuroscienceAccuracy-optimized convolutional neural networks (CNNs) have emerged as highly effective models at predicting neural responses in brain areas along the primate ventral stream, but it is largely unknown whether they effectively model neurons in the ...
