Abstract:

A topographical analysis was performed on 12 electroencephalograms EEGs collected from 10 volunteers who experienced motion sickness through cross-coupled Coriolis stimulation. Seven males and three females participated in the research conducted at the Air Force Institute of Technology, Wright- Patterson AFB. Two male volunteers participated in double-blind placebo phenytoin trials. Static brain maps and dynamic EEGs which focused on delta below 3Hz activity during the development of motion sickness revealed a seizure-like propagation pattern. With initial symptoms, a clear left parietal focus was seen in all records. A less dominant left fronto-temporal focus was present in 11 of the 12 records. As symptoms grew there was a contralateral spread possibly occipitally to the right temporal region. A steady increase in power was noticeable during the evolution of motion sickness. The 2 phenytoin trials showed less overall power when compared to their respective placebo trials. The report of this seizure-like propagation pattern during motion sickness is believed to be the first of its kind.
