Successive Induction in Larval Zebrafish

Abstract

Activating one reflex often facilitates another, antagonistic one. Since Charles Sherrington first identified successive induction more than 100 years ago, it has been demonstrated in a wide range of species, from aphids to grasshoppers to dogs and humans. We show a particularly orderly example in zebrafish (Danio rerio) larvae and identify the simple dynamic process that seems to underlie it.
