FIGURE 5.6 Responses of ascending interneuron in Locusta migratoria (Orthoptera: Acrididae) to vibratory stimuli presented to different leg pairs. (a) Response characteristics to stimulation of forelegs vs. mid- and hind-legs. Stimulus frequency 100 Hz, duration 20 msec, acceleration of 3.8 m/sec2 (filled squares), 1.7 m/sec2 (opened circles), 0.38 m/sec2 (filled circles). (Modified from Cokl, A., Otto, C., and Kalmring, K. J. Comp. Physiol. A, 156, 45-52, 1985, Figure 2a, p. 48. With permission from Springer-Verlag.) (b) Response characteristics to stimulation of fore- and midlegs with a delay of 5 msec: midlegs vibrated before forelegs (filled circles), forelegs stimulated before midlegs (open circles). The acceleration of the stimulus applied to forelegs was kept constant (3.8 m/sec2), the acceleration of the midleg stimulus is indicated on abscissa. Stimulus frequency 100 Hz, duration 20 msec. (Modified from Cokl, A., Otto, C., and Kalmring, K. J. Comp. Physiol. A, 156, 45-52, 1985, Figure 3b, p.49. With permission from Springer-Verlag.)
