(A–C) Effect of one hour or five hours of food deprivation on wild-type and tyra-2 null-mutant worm multisensory decision balance (A), exiting of a 3 M fructose ring in the absence of food odor (B), and chemotaxis to 1:1000 diacetyl (C). (*, p<0.05.)
(D and E) Effect of increasing RIM inhibition on simulated wild-type and tyra-2 null-mutant worm multisensory (D) or unisensory (E) decision balance. Vertical dashed lines indicate the degree of RIM inhibition that results in exiting rates for simulated wild-type worms that match those of real worms deprived of food for the indicated durations (see panel A). n=250 simulated worms for each genotype and strength of RIM inhibition.
