The paper investigates how s-LNv clock neurons regulate sleep through neuropeptide release and cytoneme-mediated communication with l-LNv neurons.

The paper introduces PKU tags, genetically encoded shape tags for cell labeling in light and electron microscopy, enabling multi-cell-type labeling and circuit tracing without altering behavior or transcriptomes.

The paper develops a GRAB sensor to study sNPF and ACh release dynamics, finding distinct synaptotagmins involved in each process.

The paper develops a GRAB sensor to monitor octopamine release in Drosophila and reveals its role in aversive learning through a monoamine relay circuit.

The paper investigates the timing mismatch between somatic Ca2+ activity and neuropeptide release in Drosophila sLNv neurons, finding that terminal Ca2+ spiking and neuropeptide release peak midmorning, hours before their behavioral effects.

This paper develops dual-color GRAB sensors to monitor spatiotemporal serotonin release in vivo, revealing uniform and gradient release patterns and seizure-induced waves.

The paper shows that serotonin signaling modulates the coincidence time window in Drosophila associative learning by a feedback circuit involving ACh and 5-HT.

This study identifies circadian-regulated miRNA-mRNA interactions in Drosophila using CLEAR-CLIP, revealing functional roles of specific miRNAs in circadian control.
