To respond to the world around them, animals rely on the input of a network of sensory
organs distributed throughout the body. Distinct classes of sensory organs are specialized …

Somatic sexual dimorphisms outside of the nervous system in Drosophila melanogaster are
largely controlled by the male-and female-specific Doublesex transcription factors (DSXM …

Neural circuits carry out complex computations that allow animals to evaluate food, select
mates, move toward attractive stimuli, and move away from threats. In insects, the …

Highlights•Sex-specific isoforms of Fruitless and Doublesex define dimorphic
circuitry.•Sensory pathways for chemical and auditory stimuli traced to the central …

Peripheral sensory neurons are the gateway to the environment across species. In
Drosophila, olfactory and gustatory senses are required to initiate courtship, as well as for …

Nervous systems exhibit myriad cell types, but understanding how this diversity arises is
hampered by the difficulty to visualize and genetically-probe specific lineages, especially at …

Background Neurons are one of the most structurally and functionally diverse cell types
found in nature, owing in large part to their unique class specific dendritic architectures …

Chemosensory tissues exhibit significant between-species variability, yet the evolution of
gene expression and cell types underlying this diversity remain poorly understood. To …

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 …

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