The dynamics of successive induction in larval zebrafish.
Abstract
Charles Sherrington identified the properties of the synapse by purely behavioral
means-the study of reflexes-more than 100 years ago. They were subsequently confirmed
neurophysiologically. Studying reflex interaction, he also showed that activating
one reflex often facilitates another, antagonistic one: successive induction, which
has since been demonstrated in a wide range of species, from aphids to locusts to
dogs and humans. We show a particularly orderly example in zebrafish (Danio rerio)
larvae; the behavior (locomotion) of larvae is low in dark and intermediate in light,
but low in light and substantially higher in dark when dark followed light. A quantitative
model of a simple dynamic process is described that readily captures the behavior
pattern and the effects of a number of manipulations of lighting conditions.

Until my retirement in 2007, my laboratory did experimental research on learning and
adaptive behavior, mostly with animals: pigeons, rats, fish, parakeets. We were particularly
interested in timing and memory, feeding regulation, habituation and the ways in which
pigeons and rats adapt to reward schedules. The aim is to arrive at simple models
for learning that can help to identify the underlying neural mechanisms. I continue
to do theoretical and historical work on the power law in
