Fig. 10. Simultaneous recordings from the trochanteral depressor muscles of the left and the right hind legs of Aphrodes. (A) The rapid and simultaneous jump movements of both hind legs (arrows) were preceded by a high frequency burst of spikes in both depressor muscles. Scale bar on left frame, 1 mm. (B) Displaying this burst of spikes (between the broken lines in A) on a faster time scale showed that the spikes on the two sides were not tightly coupled.
