Abstract The ability to maintain our body’s balance and stability in space is crucial for performing daily activities. Effective postural control (PC) strategies rely on integrating visual, vestibular, proprioceptive sensory inputs. While neuroimaging has revealed key areas involved PC—including brainstem, cerebellum, cortical networks—the rapid neural mechanisms underlying dynamic tasks remain less understood. Therefore, we used EEG microstate analysis within the BioVRSea experiment explore temporal brain dynamics that support PC. This complex paradigm simulates maintaining an upright posture a moving platform, integrated with virtual reality (VR), replicate sensation of balancing boat. Data were acquired from 266 healthy subjects using 64-channel system. Using modified k-means method, five maps identified best model paradigm. Differences each feature (occurrence, duration, coverage) between experimental phases analyzed linear mixed model, revealing significant differences microstates phases. parameters C showed significantly higher levels all compared other maps, whereas B displayed opposite pattern, consistently showing lower levels. study marks first attempt use during task, demonstrating decisive role and, conversely, differentiating PC These results demonstrate technique studying potential application early detection neurodegenerative diseases.
