The gastrointestinal tract has recently come to the forefront of multiple research fields. It is
now recognized as a major source of signals modulating food intake, insulin secretion and …

Until now, most brain studies have focused on small numbers of neurons that interact in
limited circuits, allowing analysis of individual computations or steps of neural processing …

Brains contain networks of interconnected neurons and so knowing the network architecture
is essential for understanding brain function. We therefore mapped the synaptic-resolution …

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 …

Aedes aegypti mosquitoes are a persistent human foe, transmitting arboviruses including
dengue when they feed on human blood. Mosquitoes are intensely attracted to body odor …

Drosophila melanogaster has a rich repertoire of innate and learned behaviors. Its 100,000-
neuron brain is a large but tractable target for comprehensive neural circuit mapping. Only …

We identified the neurons comprising the Drosophila mushroom body (MB), an associative
center in invertebrate brains, and provide a comprehensive map describing their potential …

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 …

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 …
