Fig. 6: Rules of integration between ORN classes are diverse and depend on region of the state-space and the locomotor parameter.

a Rules of integration for the effect of Or42b, Or92a on sharp turn total curvature. The three panel on the left are the effect on sharp turn. 1 = no effect; 1.46 is a 46% increase. The rightmost panel shows the interaction. Color implies that the interaction was synergistic such that the observed effect is at least 10% larger than for linear summation (orange), and at least 10% smaller (blue). b Same as (a), but for curved walk speed. The same two ORN class can have either synergistic or antagonistic interaction depending on the locomotor parameter. Synergistic and antagonistic interactions can be further delineated by whether the individual ORN activation results in an increase (solid) or decrease (hashed) in locomotor parameter. c Interactions between Or42b and three other ORN combination Or92a, Ir64a, and Ir64a;Ir75a show that rules of summation between the same ORN classes are diverse. Numbers represent interaction gain effects on locomotion (see “Methods”).
