Resting-state functional connectivity predicts recovery from visually induced motion sickness

Area of Science:

• Neuroscience
• Human Physiology
• Medical Imaging

Background:

• Visually induced motion sickness (VIMS) causes discomfort during motion-stimulus viewing.
• VIMS symptoms develop gradually and resolve over time after stimulus removal.
• Neuroimaging studies have explored VIMS onset, but recovery mechanisms remain unclear.

Purpose of the Study:

• Investigate the neural correlates of recovery from VIMS.
• Identify brain activity patterns associated with VIMS symptom resolution.
• Understand the brain mechanisms underlying VIMS recovery to inform potential interventions.

Main Methods:

• Utilized functional connectivity magnetic resonance imaging (fcMRI) to examine brain activity.
• Focused on brain regions implicated in VIMS emergence, including insular, cingulate, and visual cortices.
• Correlated functional connectivity changes with subjective reports of recovery.

Main Results:

• Identified enhanced functional connectivity patterns during VIMS recovery.
• Observed increased connectivity in networks involving insular, cingulate, and visual cortical regions.
• Found correlations between specific functional connectivity increases and subjective recovery awareness.

Conclusions:

• Enhanced functional connectivity during VIMS recovery may reflect neuroplastic changes in visual processing.
• Increased connectivity might indicate improved interoceptive awareness of bodily states.
• Findings suggest VIMS recovery involves complex neural network interactions and potential memory maintenance.
