Meet 10 neuroscientists bringing model diversity back with the funky animals they study.

Neuroscience can sometimes feel like an old mouse clubהbut it wasnיt always that way. In the 1960s and י70s, neuroscientists routinely put on their field boots to search for the לanimal that was expert at doing the task that you were interested in studying,ם says Eve Marder, university professor of biology at Brandeis University. לPeople studied insects and annelids and mollusks and every kind of animal imaginable. And if they could have studied elephants, they would have.ם

Many fundamentalהand Nobel-prize-winningהdiscoveries emerged from this approach. Recording from the squidיs giant axon, for example, revealed how action potentials work; experiments in sea slugs illuminated the molecular changes that drive learning and memory; work in barn owls unraveled sound localization; and studies in horseshoe crabs first exposed lateral inhibition in photoreceptors.

But by the end of the 20th century, model diversity had fallen out of vogue. A small band of neuroethologists continued to explore animals off the beaten path, but the majority of neuroscientists soon jumped over to standard animal models, Marder says.
