Continuously monitoring its position in space relative to a goal is one of the most essential
tasks for an animal that moves through its environment. Species as diverse as rats, bees …

Many animals can navigate toward a goal they cannot see based on an internal
representation of that goal in the brain's spatial maps. These maps are organized around …

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 …

Flexible behaviors over long timescales are thought to engage recurrent neural networks in
deep brain regions, which are experimentally challenging to study. In insects, recurrent …

Many animals rely on an internal heading representation when navigating in varied
environments,,,,,,,,–. How this representation is linked to the sensory cues that define …

Cell-type-specific tools facilitate the identification and functional characterization of the
distinct cell types that form the complexity of neuronal circuits. A large collection of existing …

Neural representations of head direction (HD) have been discovered in many species.
Theoretical work has proposed that the dynamics associated with these representations are …

Many insects use patterns of polarized light in the sky to orient and navigate. Here, we
functionally characterize neural circuitry in the fruit fly, Drosophila melanogaster, that …

Sleep is under homeostatic control, whereby increasing wakefulness generates sleep need
and triggers sleep drive. However, the molecular and cellular pathways by which sleep need …

Spatial maps in the brain are most accurate when they are linked to external sensory cues.
Here, we show that the compass in the Drosophila brain is linked to the direction of the wind …
