a, Schematic of the paired fly optogenetic activation experiment. CsChrimson was expressed only in the male. b, Target cell types. c, Time course of the probabilities of pulse (red) and sine (blue) song induced by LED stimulation. The shaded area represents the period during which LED stimulation was applied. Data are represented as mean ± s.e.m. across flies (n = 12 flies for pIP10, pMP2 and dPR1; n = 11 flies for TN1A-2). d, Time course of the song initiation probabilities (red, quiet to pulse events; blue, quiet to sine events) during LED stimulation at the irradiance of 4.0 μW mm−2 for pIP10 and TN1A-2 and 11.9 μW mm−2 for pMP2 and dPR1. For each genotype, the probabilities were calculated by aggregating data from 12 flies (pIP10, pMP2 and dPR1) or 11 flies (TN1A-2). e, Same as d but for the song switch probabilities (red, sine to pulse events; blue, pulse to sine events).
