Across a wide range of animal taxa, prosodic modulation of the voice can express emotional
information and is used to coordinate vocal interactions between multiple individuals. Within …

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

The medial preoptic area (mPOA) differs between males and females in nearly all species
examined to date, including humans. Here, using fiber photometry recordings of Ca2+ …

Animals must express the appropriate behavior that meets their most pressing physiological
needs and their environmental context. However, it is currently unclear how alternative …

In Drosophila, a dedicated olfactory channel senses a male pheromone, cis-vaccenyl
acetate (cVA), promoting female courtship while repelling males. Here, we show that …

An animal at rest or engaged in stationary behaviors can instantaneously initiate goal-
directed walking. How descending brain inputs trigger rapid transitions from a non-walking …

Aggressive social interactions are used to compete for limited resources and are regulated
by complex sensory cues and the organism's internal state. While both sexes exhibit …

It is unclear where in the nervous system evolutionary changes tend to occur. To localize the
source of neural evolution that has generated divergent behaviors, we developed a new …

Sustained changes in mood or action require persistent changes in neural activity, but it has
been difficult to identify the neural circuit mechanisms that underlie persistent activity and …

Sex differences in whole-body fat storage exist in many species. For example, Drosophila
females store more fat than males. Yet, the mechanisms underlying this sex difference in fat …
