<p>(A) Probability of pirouette behaviors in wild-type animals tracking at different electric field strengths. A single pirouette event was identified if the angular speed equaled or exceeded 110°/second in an individual track. The pirouette probability is suppressed with electric field stimuli of 1.5, 3, and 6 V/cm in comparison to non-stimulus (0 V/cm; <i>p</i> < 0.002). (B) Field stimulus and pirouette suppression in different strains. <i>eat-4(ky5)</i>, <i>nsy-5</i>/<i>inx-19</i> (AWC<sup><i>OFF/OFF</i></sup>) <i>ceh-36(ky646)</i> and AWC::<i>eat-4</i> mutant animals display defects in suppression of local search behavior with application of an electric field stimulus compared to wild type (<i>p</i> ≤ 0.00005). <i>nsy-1</i> (AWC<sup>ON/ON</sup>) animals display significant suppression of local search behavior (<i>p</i> ≤ 0.00005). AWC::caspase exhibited small, but statistically significant deficits in the suppression of search behavior (<i>p</i> = 0.0002). For all trials, error bars represent SEM; number of individual animal tracks per genotype (<i>N</i>) ≥ 154. <i>P</i>-values were determined from post-hoc pairwise comparisons of estimates obtained via general linear mixed-models. Significance was assessed using a false discovery rate of 0.05.</p
