Figure 3. Ca⁺² transients in DA ray neurons increase during arched postures.

% ΔF/F0 trace for 5 seconds. Representative recordings for individual wild-type males with (A) an arched posture during spicule insertion attempts (left), (B) with non-arched posture during spicule insertion attempts (left), and (C) arched scanning posture (left). Non-arched scanning recordings for each male are displayed on the right (A–C). A Pdat-1:unc-103(gf) transgenic male displaying an arched posture at the vulva (left) and during scanning (right) (D). The In-Contact Length % (ICL%) are the numbers located at the top of each bar taken from a representative frame for each 1 sec intervals.
