Ethan Scott packs his lab with math, physics and computer science experts to decode sensory brain networks in zebrafish models of autism.

Over the past century, scientists have used a variety of animal models to advance their understanding of the developing brain and autism.
In the past two decades, some autism researchers have turned to simple animals, such as roundworms, fruit flies and zebrafish, for their investigations. Others have sought answers from experiments with frogs, birds and even octopuses.
Researchers are increasingly turning to simple animals to learn about autism biology and find leads for new drugs.
Worms and zebrafish missing both copies of the gene CHD7 have disrupted cellular signaling, a dearth of inhibitory neurons and behavior changes — all of which are reversed by the stimulant drug ephedrine.
Mutations in autism-linked genes lead to a variety of changes in brain activity, sensory perception and sleep-wake cycles in zebrafish.
Spectrum is covering the 2020 International SYNGAP1 Scientific Conference, which took place virtually because of the coronavirus pandemic. Here we’re highlighting researchers’ reactions to noteworthy presentations.
Mutations in a top autism gene called SYNGAP1 slow the rate at which zebrafish digest food and pass waste, and may also disrupt gut function in people.
A new method that suppresses gene expression in the embryos of fish and mice may help researchers study autism genes in early development.
