Neurobiology and Insect Physiology Research

Four connectome-defined Drosophila NPF cell types sit in separate circuits with distinct, sometimes opposing functions; population-wide NPF knockdown hides these, and activity manipulation can differ from peptide loss.

Seven high-speed cameras, a hybrid 2D/3D network and body-model inverse kinematics track 50 keypoints on freely moving flies; height and speed peak together at all running speeds.

In Drosophila larvae, ventral oblique (VO) muscles drive protopodium folding, and a tri-segmental A27h–A18b3–A06c premotor excitation-inhibition motif restricts their activation to a late, forward-specific window.

Heliconius butterflies retain odour associations over eight days no better than outgroup Heliconiini, contrasting with their superior visual long-term memory, consistent with a modality-specific memory enhancement.

A FIB-SEM connectome of the male Drosophila right optic lobe sorts ∼53,000 neurons into 727 types, with neurotransmitter predictions and 577 matched split-GAL4 lines.

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.

1328 descending and 733 motor neurons of the male Drosophila nerve cord connectome were curated; direct links between them are infrequent, and intrinsic-neuron communities route control per motor system.

Roughly 23 thousand traced neurons and 10 million TBars of the male Drosophila nerve cord, reconstructed from electron microscopy, typed, and queryable in neuPrint down to motor neurons.

Aedes aegypti olfactory neurons often co-express OR, IR and sometimes GR receptors; in the maxillary palp, one neuron type responds to odorants via both OR and IR pathways.

A dense electron-microscopy reconstruction of half the fly central brain, with nearly every cell typed and queryable online, turns months of tracing partners into a database lookup.

A collection of over 18,000 Drosophila driver lines (GAL4, LexA, split-GAL4) was built, with adult male brain expression imaged for over 14,000 lines.
