A microphone array enables the vocal contribution of each socially interacting individual to be quantified, and reveals that vocalizations are exchanged between the sexes during mouse courtship.
The courtship master gene fruitless tunes functional flexibility of courtship circuitry during development instead of switching on its function as conventionally viewed.
Anatomical, behavioral and physiological evidence suggests that the aPN1-vPN1-pC1 pathway serves as a labeled line for the processing and transformation of courtship song in male Drosophila.
Sex-specific characteristics of the fruit fly courtship behavior are not specified by a single binary switch, but as a combination of traits that are modularly specified by separable genetic switches.
Functional dissection of a cluster of male-specific neurons in Drosophila reveals a neuronal circuit regulating male courtship in accordance with the internal drive state.
The sleep-courtship balance in Drosophila males is modulated by yeast/protein availability, and dopaminergic neurons projecting to the protocerebral bridge act downstream of courtship-regulating neurons for male sleep regulation.
Quantitative behavioral assays and modeling show that acoustic duetting in Drosophila during courtship relies on the detection of precisely timed cues via multiple sensory channels.
Phototaxis and courtship behavioral preferences reflect strong correlation with differences in olfactory and visual nervous system investment across five monophyletic Drosophila species, and could help explain their speciation events.
