Animal behavior is shaped by a variety of" internal states"—partially hidden variables that
profoundly shape perception, cognition, and action. The neural basis of internal states, such …

Highlights•Technical advances are producing bigger and denser Drosophila melanogaster
connectomes.•Mapping connectomics to other data types is a challenging but crucial …

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 …

Connections between neurons can be mapped by acquiring and analyzing electron
microscopic (EM) brain images. In recent years, this approach has been applied to chunks of …

Long-lasting internal arousal states motivate and pattern ongoing behaviour, enabling the
temporary emergence of innate behavioural programs that serve the needs of an animal …

Female mice exhibit opposing social behaviors toward males depending on their
reproductive state: virgins display sexual receptivity (lordosis behavior), while lactating …

Innate behaviors are frequently comprised of ordered sequences of component actions that
progress to satisfy essential drives. Progression is governed by specialized sensory cues …

The mushroom body (MB) is the center for associative learning in insects. In Drosophila,
intersectional split-GAL4 drivers and electron microscopy (EM) connectomes have laid the …

To navigate, we must continuously estimate the direction we are headed in, and we must
correct deviations from our goal. Direction estimation is accomplished by ring attractor …

We can now measure the connectivity of every neuron in a neural circuit, but we are still
blind to other biological details, including the dynamical characteristics of each neuron. The …
