Neuronal silencing through depolarization block underlies odor discrimination

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

An essential experimental control for functional connectivity mapping with optogenetics

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.

Odorant receptors mediating avoidance of toxic mustard oils in Drosophila melanogaster are expanded in herbivorous relatives

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.

Computational principles of adaptive multisensory combination in the Drosophila larva

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

Inter-species comparison of the orientation algorithm directing larval chemotaxis in the genus Drosophila

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

PiVR: an affordable and versatile closed-loop platform to study unrestrained sensorimotor behavior

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