When larval zebrafish experience whole-field visual motion, as in the random-dot task, they swim in the direction of motion - an innate behavior enabling animals to maintain position in moving water. This behavior is well-explained by the same drift-diffusion algorithm that captures human and primate behavior in analogous random-dot paradigms. We previously proposed a hypothetical circuit model that implements this algorithm via a recurrent integrator circuit in the zebrafish hindbrain that accumulates noisy visual evidence and excites downstream motor circuits after overcoming competitive inh
