The wide variety of animal behaviours that can be observed today arose through the
evolution of their underlying neural circuits. Advances in understanding the mechanisms …

Goal-directed social behaviours such as mating and fighting are associated with scalable
and persistent internal states of emotion, motivation, arousal or drive. How those internal …

The neural circuits responsible for animal behavior remain largely unknown. We summarize
new methods and present the circuitry of a large fraction of the brain of the fruit fly …

The neural circuits responsible for behavior remain largely unknown. Previous efforts have
reconstructed the complete circuits of small animals, with hundreds of neurons, and selected …

Choosing a mate is one of the most consequential decisions a female will make during her
lifetime. A female fly signals her willingness to mate by opening her vaginal plates, allowing …

Mating and egg laying are tightly cooordinated events in the reproductive life of all oviparous
females. Oviposition is typically rare in virgin females but is initiated after copulation. Here …

Principles of Neurobiology, Second Edition presents the major concepts of neuroscience
with an emphasis on how we know what we know. The text is organized around a series of …

Among the many wonders of nature, the sense of smell of the fly Drosophila melanogaster
might seem, at first glance, of esoteric interest. Nevertheless, for over a century, the 'nose'of …

Physiology and metabolism are often sexually dimorphic, but the underlying mechanisms
remain incompletely understood. Here, we use the intestine of Drosophila melanogaster to …

Insects use sex pheromones as a reproductive isolating mechanism to attract conspecifics
and repel heterospecifics. Despite the profound knowledge of sex pheromones, little is …
