Fig. 7. Kinetics of stance direction is fastest in front legs. The time course of
stance direction during turning differs between legs. (O1O3) Time
courses of outer front, middle, and hind leg, respectively, as the animal
turns to the right. (I1I3) Time courses of inner legs (see insert on
lower right). Values are means ± S.D. of 33 trials in eight
animals, every 0.54 s (14 bins per 7.5 s interval). Bold solid lines show the
time course of the exponential fitting function that explains most of the
variance. Differences between the steady state stance directions
(RCRS) and time constants of
the time course (
) are indicated in the top left corner of each diagram.
Values in grey are not statistically significant. Stance direction changes
strongest and fastest in front legs. The equally strong change in the inner
middle leg is, on average, much slower. Since the change
RCRS in the inner hind leg is
not significant, no curve fit was calculated for this data set.
