The paper shows that depolarization block silences olfactory neurons at high odor concentrations, enabling odor discrimination by creating distinct activity patterns.

The paper identifies leaky Chrimson expression as a source of false-positive signals in optogenetic functional connectivity experiments and proposes a control to mitigate this issue.

This study identifies odorant receptors in Drosophila that detect toxic mustard oils, showing that herbivorous relatives have expanded and adapted these receptors for hostplant recognition.

This study investigates how Drosophila larvae combine sensory signals through probabilistic inference, showing adaptation to signal reliability and modality-dependent mechanisms.

The paper compares chemotaxis algorithms across eight Drosophila species, finding significant inter-species variability in olfactory behavior despite shared sensorimotor routines.

PiVR is a low-cost, high-speed closed-loop system for studying sensorimotor behaviors in unrestrained animals, demonstrating applications in chemotaxis and phototaxis.
