Reduction in EEG theta power as a potential marker for spatial disorientation during flight by Gil Geva, Nir Getter, Boris Blecher, Oded Ben-Ari, Barak Gordon, Idan Nakdimon, Oren Shriki

“…Results indicate a significant decrease (34%) in theta power (4–7.5 Hz) over the left frontal region during the illusion, complemented by the occurrence of nystagmus in 72% of the trials. These findings align with previous studies linking SD and theta band changes, suggesting implications for EEG-based identification of SD in flight.…”
