Figure 3. Maximum angular displacement elicited by stimulation amplitudes varied from 0.25 V to 2.5 V.

Figure 3

A 30 Hz and 1 ms pulse width monophasic pulse train with varying amplitudes was used to determine the threshold voltage. Leg angular displacement (absolute values used for all the motions) occurred at approximately 1 V and increased steadily until 1.5 V (number of beetles = 5, 17≤ number of data points at each stimulation voltage ≤22). The angular displacement remained maximal when the stimulation voltage ranged from 1.5 to 2.5 V.
