Summary
Individuals with concussion symptoms are more susceptible to visually induced motion sickness (VIMS). This heightened sensitivity, particularly in symptomatic concussed individuals, impacts their experience with virtual environments.
Area of Science:
- Neuroscience
- Human Physiology
- Visual Perception
Background:
- Concussion can cause symptoms like dizziness and balance issues.
- Individuals with concussion may over-rely on visual input due to impaired vestibular function.
- This visual reliance may increase susceptibility to visually induced motion sickness (VIMS).
Purpose of the Study:
- To determine if individuals with concussion are at higher risk for VIMS.
- To investigate the relationship between concussion symptoms and VIMS.
- To assess the implications for using virtual reality in concussion management.
Main Methods:
- 16 individuals with concussion and 15 healthy controls viewed a virtual self-motion scene.
- Participants with concussion were categorized as symptomatic or asymptomatic.
- Visually induced motion sickness (VIMS) was measured using the Simulator Sickness Questionnaire (SSQ).
Main Results:
- Symptomatic concussed individuals reported significantly higher VIMS scores post-exposure compared to controls.
- Visual dependence correlated with VIMS severity in both concussed and control groups.
- Concussion symptoms at testing significantly increased VIMS risk and severity.
Conclusions:
- Symptomatic concussion elevates the risk and severity of visually induced motion sickness (VIMS).
- Visual dependence is a contributing factor to VIMS in both healthy and concussed individuals.
- Findings are critical for the application of virtual reality in concussion assessment and rehabilitation.

01:15Equilibrium and Balance
4.7K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

01:29The Vestibular System
39.5K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
