a The effect of spaceflight on the otolith-mediated reflex, the ocular counter-roll (OCR). The overall average of the OCR measurements showed a decreased OCR early postflight (R + 1/3, 1–3 days after return) after a 6-month space mission. In addition, the evolution of the OCR across the first 2 weeks postflight is illustrated, showing a return to baseline levels (BDC) 8–12 days after their return (R + 8/12). b The difference between 1st-, 2nd-, 3rd-, 4th-, and 5th-time flyers regarding the effect of long-duration spaceflight on the otolith-mediated OCR. All flyers (first-time to frequent flyers) show a clear decrease in early postflight (R + 1/3). However, the more the cosmonauts have flown, the less the OCR gain decreases postflight. For more details, please review Schoenmaekers et al.14.
