Transcriptional profiling of extraocular motor neurons reveals sim1a as a candidate strabismus-related gene

The paper identifies sim1a as a candidate gene for strabismus using transcriptomic analysis and CRISPR/Cas9 mutagenesis in zebrafish.

CaBLAM! A high-contrast bioluminescent Ca2+ indicator derived from an engineered Oplophorus gracilirostris luciferase

This paper introduces CaBLAM, a bioluminescent Ca2+ indicator with improved dynamic range and Ca2+ affinity, enabling high-resolution imaging of cellular activity in cultured neurons and in vivo.

Lighting and circadian cues shape locomotor strategies for balance and navigation in larval zebrafish

This study identifies distinct locomotor strategies in larval zebrafish under light and dark conditions, showing how light and circadian cues influence balance and navigation.

Tau load in select brainstem neurons predicts the severity and nature of balance deficits in the absence of cell death

The paper shows that tau load in specific brainstem neurons predicts balance deficits before cell death in zebrafish.

A brainstem circuit for gravity-guided vertical navigation

This study identifies a brainstem circuit in larval zebrafish that converts gravitational signals into vertical navigation by maintaining consistent heading.

Motor neurons are dispensable for the assembly of a sensorimotor circuit for gaze stabilization

The paper shows motor neurons are not required for proper connectivity in the vestibular reflex circuit for gaze stabilization.

Scalable Apparatus to Measure Posture and Locomotion (SAMPL): a high-throughput solution to study unconstrained vertical behavior in small animals

The paper introduces SAMPL, a high-throughput system for measuring posture and locomotion in small animals, demonstrating its use in zebrafish and showing genetic and developmental effects on movement.
