Hidden Markov Model Links Zebrafish Brain Behavior
Dommanget-Kott et al. (published January 5, 2026) apply three-state Hidden Markov Models to zebrafish larvae behavior and ARTR calcium imaging, identifying leftward, rightward, and forward states. The HMMs accurately capture bout-type persistence, temperature dependence, and inter-individual variability, and neural-state sequences generate synthetic swim trajectories mirroring behavioral statistics. The study provides open-source code and data for cross-modal modeling of brain–behavior relationships.
Scoring Rationale
Solid cross-modal, peer-reviewed study with usable code, but applies established HMM methods within a niche experimental system.
