Although males and females largely share the same genome and nervous system, they
differ profoundly in reproductive investments and require distinct behavioral, morphological …

behavior.•A class of sexually dimorphic neurons may contain multiple subclasses.•Sex …

Male and female brains display anatomical and functional differences. Such differences are
observed in species across the animal kingdom, including humans, but have been …

Summary Background Courtship behavior in Drosophila has been causally linked to the
activity of the heterogeneous set of∼ 1500 neurons that express the sex-specific transcripts …

Behavioral sex differences primarily derive from the sexually dimorphic organization of
neural circuits that direct the behavior. In Drosophila melanogaster, the sex-determination …

Neurogenetic analyses in the fruit fly Drosophila melanogaster revealed that gendered
behaviors, including courtship, are underpinned by sexually dimorphic neural circuitries …

Understanding how genes influence behavior, including sexuality, is one of biology's
greatest challenges. Much of the recent progress in understanding how single genes can …

It remains an enigma how the nervous system of different animal species produces different
behaviors. We studied the neural circuitry for mating behavior in Drosophila subobscura, a …

Males of Drosophila melanogaster exhibit stereotypic courtship behavior through which they
assess potential mates by processing multimodal sensory information. Although previous …
