    Experiment Description

    Research Overview

    • Otolith Assessment During Postflight Re-adaptation (Otolith) will assess otolith (small bones of the inner ear) function before and after space flight to this evaluate otolith-ocular response (OOR) and the subjective visual vertical (SVV) to assess unilateral utricle function. Vestibular evoked myogenic potentials (VEMP) will be recorded in order to assess unilateral saccule function.


    • Together this represents a comprehensive examination of all aspects of the otolith system, providing critical information on the validity of the otolith asymmetry hypothesis and on the post flight adaptation of the individual otolith functions.
