The paper identifies LC17 neurons and their electrical synapses as critical for visual approach behavior in fruit flies.

The paper uses artificial neural networks to classify neurotransmitters from electron microscopy images of Drosophila melanogaster synapses, achieving high accuracy and revealing ultrastructural differences.

The paper investigates the role of the APL neuron in larval Drosophila, finding that optogenetic activation can induce a rewarding effect through dopaminergic pathways.

The paper identifies two opposing Drosophila ellipsoid body neurons, R3m and R3d, that promote and suppress sleep through distinct effects on sleep duration and architecture.

Annotating the 127,978-neuron FlyWire fly connectome yields 4,552 cell types, 3,094 cross-validated against the hemibrain; cell-type edges above 10 synapses or 1.1% of input recur over 90% across hemispheres.

The paper maps the synaptic-resolution connectome of a Drosophila larva brain, identifying neuron types, circuit motifs, and structural features.

The paper creates an atlas of the developing Tribolium castaneum brain and compares it to Drosophila melanogaster, finding conserved anatomy but divergent developmental timing.

This study identifies neural circuitry in Drosophila that processes skylight polarization signals for navigation, revealing a map-like organization in the visual pathway.

The paper identifies developmentally arrested precursor neurons in Drosophila that form an embryonic blueprint for the central complex.

The paper provides a systematic genetic-neuroanatomical analysis of the Drosophila ellipsoid body neuropil, identifying R-neuron subclasses and their connectivity patterns.
