We hypothesized that visual and/or neck proprioceptive inputs contribute to tilt perception instead of otolith input during long-term space flight. To test this, we will measure the subjective visual body axis (SVBA) and ocular counter-rolling (OCR) at various body roll-tilt angles relative to the inner-cabin vertical, with and without head roll-tilt relative to the body, with and without visual information. If the error in the SVBA or OCR depends on visual information with respect to the inner-cabin vertical, then visual inputs must contribute to tilt perception. If the error in SVBA or OCR depends on head tilt relative to the body without visual information, then neck proprioceptive inputs must contribute to tilt perception. To examine the long-term adaptive changes in tilt perception, the SVBA and OCR will be observed throughout the entire space flight. As tilt perception is one of the most important components of spatial orientation, which is essential for safety and a comfortable life in space, it is necessary to clarify the mechanism of tilt perception in space.
