Abbas F, Meyer MP (2014) Fish vision: size selectivity in the zebrafish retinotectal pathway. Curr Biol 24: R1048-50

A recent study has shown that the zebrafish tectum processes inputs from the retina tuned to ethologically relevant size classes, suggesting a role for the tectum in selecting approach or avoidance behaviours based on size-based categorization of visual targets.
