How to Study Zebrafish? In 3-D (IMAGE) NYU Tandon School of Engineering Caption In the first experiments of their kind, NYU Tandon researchers and their colleagues found significant discrepancies in data generated when tracking the social behavior of zebrafish in two dimensions as opposed to 3-D. And although 3-D tracking is far more expensive, it could lead to a reduction in the number of fish needed for experiments.
