Fig. 5. Male responses to paired playbacks of female EODs. Responses are total amount of time males spent within 10 cm of a given playback electrode (A,B) and total number of bursts produced by the same males within 10 cm (C,D). Ordinate values are sums over each pair of trials in which the same set of EODs was presented to a subject. Results are shown separately for type II males (left panels) and type I males (right panels). Box-and-whisker plots are color coded to the playback EODs (shown at the bottom as overlays of amplitude-normalized voltage traces, each 2 ms in total duration). Small squares are mean responses; vertical ranges of rectangles are means ± s.e.m.; and whiskers are means ± s.d. Means connected by dotted lines differ significantly: ^*P<0.05; ^**P<0.01.
