(a) The electrophysiological response of antennae (red) and hairs (blue) of Cheilosia albipila to a weak electric field applied. The graph indicates the change in rate of firing of nerves of antennae and the hairs to a weak electric field stimulus applied and the blue lines indicate the stimulus. (b) The electrophysiological response of antennae (red) and hairs (blue) of Eristalis tenax to a weak electric field applied. The graph indicates the change in rate of firing rate of nerves of antennae and the hairs to an electric field stimulus applied and the blue lines indicate the stimulus. The bars represent the numbers of spikes per second per fly.
