Fig. 4. The gain of the roll-induced static vestibuloocular reflex (rVOR) in
Xenopus laevis tadpoles with lordotic tail. Post-flight observations
about the rVOR gain from tadpoles that flew on the 9.2-day SMM-06 mission
compared to their ground-reared siblings. Same animals as in
Fig. 3. rVOR gain30 = ratio
between the angular eye movement and the lateral roll of 30° from the
horizontal to the inclined position. For further explanations, see
