  Objective The different profiles of vestibular habituation in pilots and common people were explored after their Coriolis test selection.Methods Twelve healthy men and 14 pilot students passed the Coriolis test selection and participated in this experiment.They were exposed to five-day continuous or intermittent Coriolis adaptation training.The vestibular autonomic responses such as motion sickness symptom, ECG, EGG, EOG, facial skin infrared images and blood biochemistry indexes elicited by Coriolis test were monitored at 1 st day, 1 st week, 2nd week, 4th week, 5th week, 9th week and 14th week after training.Results It was found that subjects all passed the 10min continuous or 15min intermittent Coriolis adaptation training.For common healthy men, after Coriolis training the low motion sickness symptom scores can maintain 1 or 2 weeks, the habituation of autonomic responses was about 1 week, the endocrine system response held for 2 weeks, the habituation of facial skin was about 2 weeks and the slow phase speed of EOG can maintain for 3 months.For pilot students, the low motion sickness symptom scores lasted for 5 weeks, the EGG habituation was about 2 weeks, the slow phase speed of EOG can maintain for 9 weeks, but the autonomic responses had no habituation effects.Conclusion It was suggested that pilots were a special group of people, and the profile of vestibular habituation presented a dynamic changes expression irn respective aspects of vestibular autonomic responses.
