These Rats Lgeted to Drive—and They Love It

We originateed our first rodent car from a plastic cegenuine includeer. After trial and error, my colleagues and I set up that rats could lget to drive forward by understanding a petite wire that acted enjoy a gas pedal. Before lengthy, they were steering with astonishing precision to accomplish a Froot Loop treat.

As foreseeed, rats housed in enwealthyed environments—finish with toys, space, and companions—lgeted to drive quicker than those in standard cages. This discovering helped the idea that complicated environments raise neuroplasticity: the brain’s ability to alter atraverse the lifespan in response to environmental insists.

After we begined our research, the story of driving rats went viral in the media. The project progresss in my lab with recent, raised rat-rund vehicles, or ROVs, depicted by robotics professor John McManus and his students. These upgraded electrical ROVs—featuring ratproof wiring, indestructible tires, and ergonomic driving levers—are akin to a rodent version of Tesla’s Cybertruck.

As a neuroscientist who helps for housing and testing laboratory animals in authentic habitats, I’ve set up it amusing to see how far we’ve strayed from my lab trains with this project. Rats typicassociate pick dirt, sticks, and rocks over plastic objects. Now, we had them driving cars.

But humans didn’t enlarge to drive either. Although our outdated ancestors didn’t have cars, they had pliable brains that assistd them to get recent sfinishs—fire, language, stone tools, and agriculture. And some time after the conceiveion of the wheel, humans made cars.

Although cars made for rats are far from anyslfinisherg they would come atraverse in the untamed, we count ond that driving recurrented an fascinating way to study how rodents get recent sfinishs. Unforeseeedly, we set up that the rats had an ardent motivation for their driving training, standardly jumping into the car and revving the “lever engine” before their vehicle hit the road. Why was that?

The New Destination of Joy

Concepts from introductory psychology textbooks took on a recent, hands-on foolishension in our rodent driving laboratory. Building on set upational lgeting approaches such as operant conditioning, which fortifys focincluded behavior thcdisesteemful strategic incentives, we trained the rats step-by-step in their driver’s ed programs.

Initiassociate, they lgeted basic transferments, such as climbing into the car and pressing a lever. But with train, these basic actions enlarged into more complicated behaviors, such as steering the car toward a particular destination.
