The Brain

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.

Frogs are useful for autism research for a slew of reasons, including the fact that the animals’ initial development occurs outside of the mother’s body in plain view.

Researchers are increasingly turning to simple animals to learn about autism biology and find leads for new drugs.

Parallels between how birds learn to sing and how children learn to speak provide a window into the roots of language difficulties in autism.
