A sexually dimorphic transcriptional switch in sensory neurons integrates information about microbial environment and nutritional state to regulate exploratory behavior in C. elegans..
Perceived imminence of threat and resulting intensity of defensive responses during serial compound stimulus conditioning are determined by auditory stimulus salience, not cue sequence as recently reported.
The courtship master gene fruitless tunes functional flexibility of courtship circuitry during development instead of switching on its function as conventionally viewed.
Male-type aggressive and courtship behaviors of the fruit flies are differentially specified by two sex-determining genes, providing a substrate for the evolution to sculpt these two behaviors independently.
In the brain of medaka fish, neuropeptide B acts directly downstream of estrogen in a female-specific but reversible manner to mediate female receptivity to male courtship.
Co-evolution of sexually dimorphic reinforcement systems for song can explain the coexistence of the seemingly contradictory traits of gregariousness and monogamy in social songbirds.
The sex-specificity of a transcription factor required for sexual differentiation of a neural circuit is regulated by a novel post-transcriptional mechanism.
The balance between sleep and sex drives determines whether male flies sleep or court, and a subset of octopaminergic neurons interact with the Fruitless-expressing courtship circuit to suppress sleep for sustained courtship.
Sex-specific neuropeptide signaling in the shared sensory nervous system regulates sexually dimorphic gene expression and male-specific behavior in C. elegans.
