Spontaneous neural activity in the developing ant olfactory system

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

The chemosensory system of the clonal raider ant larva

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.

Rare sex punctuates strict asexual reproduction in the clonal raider ant, Ooceraea biroi

The paper shows that the clonal raider ant, Ooceraea biroi, occasionally reproduces sexually, generating new genetic combinations and potentially overcoming asexuality costs.

Tolerance toward foreigners in ants requires chronic exposure for establishment but only sporadic exposure for maintenance

The paper shows that ants can develop tolerance toward foreigners through chronic exposure but maintain it with sporadic exposure.

A reference brain for the clonal raider ant

The paper generates a reference brain for the clonal raider ant using confocal microscopy and 3D registration, revealing interindividual brain variability despite genetic and age homogeneity.

FERAL: A Supervised Video-Understanding System for Direct Video-to-Behavior Mapping

FERAL is a video-understanding system that maps raw video directly to behavioral labels, outperforming existing methods across species and conditions with less training data.

Heterozygosity at a conserved candidate sex determination locus is associated with female development in the clonal raider ant (Ooceraea biroi)

The paper identifies a conserved CSD locus in Ooceraea biroi where heterozygosity triggers female development, showing evolutionary conservation across ant species.

Transcriptional Interference Gates Monogenic Odorant Receptor Expression in Ants

The paper shows that transcriptional interference, including non-canonical readthrough and bidirectional promoters, suppresses upstream OR genes while allowing single OR expression in ants.

Pheromone representation in the ant antennal lobe changes with age

This study examines how odor coding in the antennal lobe of ants changes with age, finding that alarm pheromone responses in specific glomeruli increase while general odorant responses decrease.

Sparse and stereotyped encoding implicates a core glomerulus for ant alarm behavior

The paper shows that ants use a single glomerulus to encode alarm pheromones, indicating stereotyped and narrow tuning for these signals.

anTraX: high throughput video tracking of color-tagged insects

anTraX tracks color-tagged insects in videos using neural networks and graph representation, enabling high-throughput analysis of group behavior with minimal human involvement.
