[Changes of early components of auditory ERPs during HDT-simulated weightlessness].
Objective. To study changes of early components of the auditory ERPs during simulated weightlessness. Method. The event-related potentials (ERPs) during an auditory location discrimination were compared between head down tilt (HDT) and head up tilt (HUT) conditions in 14 normal subjects. Result. The early components of T-ERPs and NT-ERPs decreased significantly during HDT as compared with that during HUT. The reduction of mean potential amplitude during HDT was more marked at left-forehead area (F5). Conclusion. These data provided further evidence showing that the early activity process of brain was also affected by simulated weightlessness.
