This study investigates spontaneous neural activity in developing ant olfactory sensory neurons and finds stage-dependent patterns similar to mammals.

This paper uses information-theoretic methods to analyze tsetse fly antenna responses to odors, finding that trichoid sensilla carry more odor identity information than basiconic sensilla.

The paper uses a connectome model of the fruit-fly nervous system to simulate motor recovery after neuronal loss, finding that targeted cell replacement based on identity and connections improves recovery.

This study identifies a male-specific role for SP-SPR signaling in regulating mating-induced Sex peptide replenishment in Drosophila, suggesting an ancestral function before its known role in female post-mating responses.

The paper investigates sex-specific regulation of CaMKII in Drosophila, showing differences in steady-state and activity-dependent levels between males and females without affecting plasticity.

This study identifies task- and leg-specific motor modules in Drosophila that enable curve walking by reconfiguring leg kinematics for arcs and turns.

This study measures the critical flicker fusion frequency of compound eyes and ocelli in blowflies to understand their temporal resolution capabilities.

The paper introduces a new assay, FLAME, to measure motivation in Drosophila by assessing willingness to overcome agarose barriers for nutrients, showing dopamine neuron activity is required for amino acid seeking.

This study investigates whether pilifers provide mechanosensory feedback during floral tracking in hawkmoths, finding that they respond to lateral motions with rapid latency and extensive neural connections.

The paper identifies serial homology between neuronal populations in the Drosophila melanogaster brain and ventral nerve cord using lineage reporters, single-cell transcriptomics, and a connectome.

The paper shows that nonlinear sensory integration in C. elegans creates configural olfactory representations, linking neural dynamics to perceptual outcomes.

This study shows that food perception alone, through olfactory signaling and serotonin receptors, stimulates oviposition in Drosophila without requiring nutrient intake.

This study shows that prior high effort in C. elegans increases subsequent food approach and aversive barrier crossing, with effects lasting up to 1 hour.

The paper identifies a male-specific neural circuit in Drosophila that mediates appetitive thirst by integrating neuropeptide signals and regulating motivated behaviors.

The paper shows that LITE-1 in C. elegans uses distinct genetic pathways for photosensation and chemosensation of diacetyl.

This study identifies Gq signaling in dopaminergic neurons as a memory suppressor in Drosophila using aversive conditioning and imaging techniques.

This study tests positive and negative cognitive biases in cockroaches to assess the presence of affective states in invertebrates.

The paper shows that optic flow-processing interneurons in butterflies increase baseline spiking activity during wing flapping and phase-lock to the wing-beat cycle, suggesting suppression of self-generated visual motion signals.

The paper shows that dendrite regrowth in Drosophila PNS neurons depends on RTKs and epidermal remodeling during metamorphosis, linking pruning and regrowth to ecdysone signaling.

This study identifies Neprilysin 1 in the mushroom bodies as a regulator of SIFamide levels, which control feeding behavior in Drosophila melanogaster by shaping SIFamidergic signaling.

The paper introduces NeuroGraphBench, a tool for interactively exploring Drosophila connectomes to model neural circuit function.

This paper shows how hunger reconfigures a reward circuit in Drosophila to support memory formation by switching dopamine neuron activity modes.

The paper annotates 6,368 neurons across 1,772 driver lines in Drosophila using electron microscopy data and manual scoring, estimating the fraction of the central nervous system labeled by the collection.

This study characterizes the chemosensory system of clonal raider ant larvae, identifying odorant and ionotropic receptor neurons and their projections in the central nervous system.

This study shows male fruit flies exhibit stronger social buffering of freezing responses to threats than females, with neuronal sex identity as the underlying cause.

This study identifies NLP-40 and AEX-2 as regulators of escape behaviors during anoxia in C. elegans, showing their role in modulating locomotor activity and survival.

This study investigates how Drosophila males decide to stay or switch behaviors in response to competing social and environmental cues using a closed-loop paradigm and neural imaging.
