The paper studies how duplicated odorant receptor genes in Drosophila gain new expression in olfactory sensory neurons, showing evolutionary recoding without new neuron lineages.

The paper shows that Drosophila species prefer odour components most distinctive in their natural host blends, revealing that olfactory behaviours exploit the statistical structure of odour environments.

The paper investigates temperature preference behavior evolution in Drosophila species by analyzing over 2400 larvae and using agent-based modeling to show that behavior differences arise from circuit balance, not sensitivity changes.

The paper shows that expanded sensory neuron populations in Drosophila enhance odor tracking without increasing projection neuron sensitivity.

The paper uses Targeted DamID to profile rare Drosophila sensory neurons, identifying transcription factors and guidance molecules involved in neuron fate and wiring.

This study identifies molecular and neuronal changes underlying behavioural divergence in Drosophila sechellia through mutational analysis and calcium imaging.
