Purple arrows indicate female-specific, mating-dependent modulations of sleep, and brown arrows indicate male-specific sleep modulations in response to the presence of female cues. Gray italic letters indicate neuronal names. Solid arrows represent established neuronal connections (but do not necessarily represent monosynaptic connections); dotted arrows represent uncharacterized but potential neuronal connections. Data sources: [31, 56, 64, 65, 68, 71, 72].
