Fig. 8. Original data from 200 ms load-clamp experiments. (A) Change in length,
force and stimulation (black line) vs time for load-clamp trials at a
high clamp force (2.60 N, blue lines) and a low clamp force (0.31 N, red
lines). The depressor mandibulae muscles were stimulated isometrically for 200
ms before the load was reduced. (B) Original records of force (left) and
change in length (right) vs time from load-clamp experiments
(N=3 toads). Numbers to the right of the force traces indicate change
in load (
F). Note that length traces (right) begin 200 ms
after the onset of muscle stimulation.
