Olfactory learning modulates a neural circuit mediating innate odor-guided behavior in Drosophila

This study shows that olfactory learning modulates second-order olfactory neurons in Drosophila, affecting innate odor-guided behavior through bidirectional plasticity.

Experience-dependent plasticity of a highly specific olfactory circuit in Drosophila melanogaster

The paper shows that a specific olfactory circuit in Drosophila melanogaster undergoes structural changes after exposure to geosmin, leading to behavioral adaptation.

Higher-order olfactory neurons in the lateral horn supports odor valence and odor identity coding in Drosophila

This study examines how odor information is transformed and represented in higher-order neurons of the Drosophila lateral horn, finding that these neurons encode odor valence and identity through specific response patterns.

An ammonium transporter is a non-canonical olfactory receptor for ammonia

The paper identifies an ammonium transporter, Amt, as a non-canonical olfactory receptor for ammonia in insects, showing it mediates neuronal and behavioral responses.

Alcohol boosts pheromone production in male flies and makes them sexier

Alcohol exposure increases pheromone production in male flies, enhancing courtship success, but methanol is toxic, requiring a balance between benefits and risks.

Mate discrimination among subspecies through a conserved olfactory pathway

The paper identifies two male-specific pheromones in Drosophila mojavensis subspecies and shows how they contribute to sexual isolation through conserved sensory pathways and differential interpretation.
