Case Studies of Remarkable VR Motion Sickness Resistance: A Judo Practitioner and a Commuter

Among 41 participants, two males exhibited no motion sickness (MS) at all during a VR-based cognitive discrimination task. The first, a judo practitioner with 16 years of mid-air balance control training, and the second, a commuter accustomed to reading while commuting, showed suppressed beta activity between cognitive and sensorimotor domains in our EEG analysis, associated with better cognitive behavioral performance. The judo practitioner demonstrated stronger suppression and superior cognitive behavioral performance. These findings raise whether beta activity suppression between cognitive and sensorimotor cortical domains reflects compensatory reticular neuron activation in the deep brainstem under a proposed MS habituation mechanism.
