Angle dependent choice of reversal and curve avoidance. a Relationship between the angle of encounter and behavioral maneuvers chosen during acidic pH avoidance behavior in wild-type C. elegans. The distance from the origin of the coordinate to each dot represents the time at which the behavior occurred. The angle between the horizontal axis and a line between the origin and each dot represents the angle of encounter into the acidic region (theta in Fig. 1). We only considered the acute angle in every avoidance behavior. b The ratio of the behavioral choice between curve and reversal avoidance, binned every 10 degrees. The number of events observed in each bin has been indicated in the bar graph. In most experiments, we observed around 500 avoidance events from more than 10 worms. Acidic agar strips containing 100 mM HCl were used to form a gradient on a plate containing 5 mM potassium phosphate buffer (pH 6.0)
