Optic Flow Drives Human Visuo-Locomotor Adaptation

Two strategies can guide walking to a stationary goal: (1) the optic-flow strategy, in which one aligns the direction of locomotion or "heading" specified by optic flow with the visual goal; and (2) the egocentric-direction strategy, in which one aligns the locomotor axis with the perceived egocentric direction of the goal and in which error results in optical target drift. Optic flow appears t...

A novel optic flow pattern speeds split-belt locomotor adaptation.

Visual input provides vital information for helping us modify our walking pattern. For example, artificial optic flow can drive changes in step length during locomotion and may also be useful for augmenting locomotor training for individuals with gait asymmetries. Here we asked whether optic flow could modify the acquisition of a symmetric walking pattern during split-belt treadmill adaptation....

Stroke affects locomotor steering responses to changing optic flow directions.

BACKGROUND Stroke patients manifest steering difficulties during walking, which may arise from an altered perception of visual motion. OBJECTIVE To examine the ability of stroke patients to control their heading direction while walking in a virtual environment (VE) describing translational optic flows (OFs) expanding from different directions. METHODS The authors evaluated 10 stroke patient...

Visuo-proprioceptive interactions during adaptation of the human reach.

We examined whether visual and proprioceptive estimates of transient (midreach) target capture errors contribute to motor adaptation according to the probabilistic rules of information integration used for perception. Healthy adult humans grasped and moved a robotic handle between targets in the horizontal plane while the robot generated springlike loads that varied unpredictably from trial to ...
