Astronauts eye-head coordination dysfunction over the course of twenty space shuttle flights

CONCLUSIONS: The in-flight alterations in EHC were presumably the result of a combination of several factors, including a transfer from allocentric to egocentric reference for spatial orientation in absence of a gravitational reference, the generation of slower head movements to attenuate motion sickness, and a decrease in smooth pursuit and vestibulo-ocular reflex performance. These results confirm that humans have several strategies for gaze behavior, between which they switch depending on the environmental conditions.PMID:37248929 | DOI:10.3233/VES-220127
