Fig. 6. Post-flight observations of the rVOR amplitude (A,B) and rVOR gain (C,D)
from tadpoles that flew on the 10-day German D-2 mission (STS-55, 1993)
compared to their ground-reared siblings. At the onset of the mission,
tadpoles had reached the developmental stages 33-36. Observations were from
post-flight days 2-6 (A,C) and 9-12 (B,D). During each period, animals were
tested once. rVOR amplitude and rVOR gain30, cf.
Fig. 2. Filled circles,
microgravity tadpoles (0g); 0g-animals were
grouped according to the development of lordosis or normal development. Open
circles, 1g-animals from the in-flight control
(F1g) and from the ground control (G1g).
Numbers at the abscissa indicate sample size. Groups that differ significantly
are connected by brackets; levels of significance (P) are shown.
