Effect of mechanical shock on seizuring behavior for female and male adult flies of para^bss or OrR genetic background. (A) Schematic of the different phases of seizure after a mechanical shock [modified from Parker et al. (38)]. (B) Result of para^bss gene sequencing in seizuring and non-seizuring males to test for the presence of the PHE mutation in position 1699 of the protein. All flies have the mutation. (C) Mechanical stimulation did not induce seizuring in OrR flies. para^bss flies showed high proportion of seizuring at t = 0, the percentage of flies recovered increased as a function of time. The graph shows the mean % of flies recovered ± SEM [para^bss females n = 6 (60 flies); para^bss males n = 7(70 flies); OrR females n = 3 (30 flies); OrR males n = 3(30 flies)]. (D) Mean recovery time comparing males and females para^bss (_{Mann−Whitney}U = 667, n_females = 51, n_males = 41, P = 0.0034 two-tailed).
