High-throughput multi-camera array microscope platform for automated 3D behavioral analysis of swimming zebrafish larvae
This paper introduces a novel high-throughput 24-camera array microscope platform with a co-designed 'mirrored well plate' for 3D behavioral analysis of swimming zebrafish larvae. It enables snapshot imaging of up to 48 wells from two orthogonal directions (top and side views). An efficient machine learning algorithm provides accurate 3D position estimation and tracking, allowing for automated 3D skeletal tracking, swim bladder morphological dynamics, and kinematics at high frame rates. This scalable solution is broadly compatible with standard lab workflows for pharmacology, toxicology, and neuroscience, offering enhanced sensitivity in detecting subtle drug-induced phenotypes.
Executive Impact & Strategic Benefits
This high-throughput 3D behavioral analysis platform for zebrafish larvae addresses a critical gap in drug discovery and neuroscience by providing unprecedented detail on locomotor and morphological dynamics. By enabling parallelized 3D tracking across 48 wells, it accelerates the identification of subtle drug-induced phenotypes, enhancing the sensitivity and interpretability of preclinical research. The standardized well plate and automated analysis streamline workflows, making it a scalable solution for complex biological studies.

Enhanced Behavioral Dimension
Ethanol Exposure Analysis
The platform revealed that 0.5% ethanol exposure in zebrafish larvae led to significantly elevated average speed, increased movement frequency, and exaggerated tail angles, which were largely underestimated or obscured in conventional 2D analysis. This demonstrates the critical importance of 3D tracking for detecting subtle drug-induced locomotor changes.
Neuroactive Compounds & Swim Bladder Dynamics
Analysis of neuroactive compounds (Nicergoline, 3-CPMT) showed distinct axial motion profiles and swim bladder morphological changes. Nicergoline restricted mobility near the water surface with larger swim bladders, while 3-CPMT caused bottom-dwelling with low volume, deflated swim bladders. These 3D insights into buoyancy regulation are inaccessible with traditional methods.
