Analysis of the distance of a worm from an attractant region. (A) Left: configuration of an assay plate. Right: the distance (red line) and the angle formed by a worm (P), the center of attractant region (Q) and the center of region C (O). The distance and the angle for the attractant in region A are defined similarly. (B-G) The distance of a worm from attractant. The distances in simultaneous presentation of 15°C and 0.03 M sodium chloride (B and C), 15°C and 0.07 M sodium chloride (D and E) and 15°C and isoamyl alcohol (F and G) are shown alongside the results from each single presentation. Each data point is presented as the mean ± SEM. SEM is indicated by grey shading.
