The paper uses voltage imaging to show how serotonergic neurons in the raphe encode action outcomes and modulate motor vigor during learning in larval zebrafish.

This study shows that serotonin modulates brain-wide neural dynamics during motor adaptation in zebrafish through both global and compartmentalized effects.

This study uses zebrafish behavior tracking to show psilocybin increases rapid swimming and prevents stress-induced irregular swimming, suggesting stimulatory and anxiolytic effects.

This study evaluates dimensionality reduction methods for calcium imaging data and introduces CILDS, which outperforms existing methods in recovering low-dimensional neural activity.

PyZebrascope provides an open-source platform for whole-brain neural activity imaging in zebrafish using light-sheet microscopy, enabling high-throughput and stable data acquisition.

The paper uses voltage imaging to identify spinal circuits in zebrafish that modulate locomotor adaptation by characterizing a novel sub-population of V3 neurons.

The paper introduces a new genetically encoded voltage indicator, Voltron, which improves brightness and photostability for extended in vivo voltage imaging in mice, zebrafish, and fruit flies.

This paper develops a genetically encoded fluorescent sensor, iGABASnFR, to monitor GABA in vivo and demonstrates its use in tracking GABA dynamics in various neural contexts.

This study uses orexin-Flp knock-in mice to distinguish orexin-dependent and -independent functions of orexin neurons, finding orexin is essential for sustained arousal and basic neuronal properties.
