Summary

Altering visual feedback during walking changes perception of self-motion and step characteristics. These adaptive changes in locomotion demonstrate how the brain recalibrates movement based on altered sensory information, adhering to natural constraints.

Area of Science:

  • Neuroscience
  • Biomechanics
  • Human Perception

Background:

  • Locomotion control adapts to altered sensory-motor relationships.
  • Previous research indicates plasticity in motor control when sensory feedback is manipulated.

Purpose of the Study:

  • To investigate adaptive changes in human locomotion and perception.
  • To examine how altered visual feedback affects self-motion perception and voluntary stepping.

Main Methods:

  • Subjects walked in place on a rotary treadmill with manipulated visual feedback (altered optical flow velocity).
  • Perceptual and motor responses, including perceived self-motion, step characteristics, and effort, were recorded.

Main Results:

  • Increased or reversed optical flow velocity led to significant changes in perceived self-motion.

  • Subjects reported alterations in step size, rate, and direction, as well as perceived effort.
  • The stability of a hand-held support bar was also affected by the altered visual feedback.

    • Conclusions:

    • Perceptual remappings in response to altered visual feedback during locomotion follow predictable patterns.
    • These findings suggest that the human motor system recalibrates based on visual cues, even when the visual environment is perceived as stable.
    • The results support the existence of 'terrestrial constraints' governing adaptive locomotion and perception.
