Temporal synchrony effects of optic flow and vestibular inputs on multisensory heading perception

open access: yesCell Reports, 2021
Summary: Precise heading perception requires integration of optic flow and vestibular cues, yet the two cues often carry distinct temporal dynamics that may confound cue integration benefit.

Optic flow

open access: yesScholarpedia, 2013
Optic flow refers to the image motion of the environment projected on the retina during our movement in the world. The term was first coined by James J. Gibson and played a key role in the development of the ecological approach to visual perception, an approach that emphasizes studying human perception in the natural environment rather than in a ...

Species-specific flight styles of flies are reflected in the response dynamics of a homologue motion sensitive neuron

open access: yesFrontiers in Integrative Neuroscience, 2012
Hoverflies and blowflies have distinctly different flight styles. Yet, both species have been shown to structure their flight behaviour in a way that facilitates extraction of 3D information from the image flow on the retina (optic flow).

Activity Strength within Optic Flow-Sensitive Cortical Regions Is Associated with Visual Path Integration Accuracy in Aged Adults

open access: yesBrain Sciences, 2021
Spatial navigation is a cognitive skill fundamental to successful interaction with our environment, and aging is associated with weaknesses in this skill.

Larger Head Displacement to Optic Flow Presented in the Lower Visual Field

open access: yesi-Perception, 2019
Optic flow that simulates self-motion often produces postural adjustment. Although literature has suggested that human postural control depends largely on visual inputs from the lower field in the environment, effects of the vertical location of optic ...

Processing of Visual Signals Related to Self-motion in the Cerebellum of Pigeons

open access: yesFrontiers in Behavioral Neuroscience, 2013
In this paper I describe the key features of optic flow processing in pigeons. Optic flow is the visual motion that occurs across the entire retina as a result of self-motion and is processed by subcortical visual pathways that project to the cerebellum.

On Refractive Optical Flow [PDF]

open access: yes, 2004
This paper presents a novel generalization of the optical flow equation to the case of refraction, and it describes a method for recovering the refractive structure of an object from a video sequence acquired as the background behind the refracting object moves.

Gaze strategy in the free flying zebra finch (Taeniopygia guttata). [PDF]

open access: yesPLoS ONE, 2008
Fast moving animals depend on cues derived from the optic flow on their retina. Optic flow from translational locomotion includes information about the three-dimensional composition of the environment, while optic flow experienced during a rotational ...

Perceiving blurry scenes with translational optic flow, rotational optic flow or combined optic flow

open access: yesVision Research, 2019
Perceiving the spatial layout of objects is crucial in visual scene perception. Optic flow provides information about spatial layout. This information is not affected by image blur because motion detection uses low spatial frequencies in image structure.
