Caring for Cattle Expands the Mind of a Neuroscientist

Gregory Berns launches a book on the secret world of cows and a class on the psychology of sustainability

Talking Dogs Farm lies amid pine forests and wetlands an hour south of Atlanta. You turn onto a gravel driveway, drive through lush, green fields populated with a small herd of miniature Zebu cattle, then pass through a sun-speckled tunnel of pink-blooming crepe myrtle to reach a white, two-story farmhouse. Gregory Berns, Emory professor of psychology, moved here with his wife, Kathleen, during the COVID-19 pandemic.  

Berns emerges from the house to greet his visitor, accompanied by a canine entourage. Gus, a young Hungarian hunting dog known as a Vizsla, shoots out sleek as an arrow. Cato and Argo, mixed breeds the size of small bears, lumber behind Gus, booming like twin cannons. Callie, a compact, southern-squirrel-hunting breed, wobbles with a painstaking, arthritic gait at the back of the pack.

Callie became famous in 2012 as the first dog to enter a functional magnetic resonance imaging machine to lie awake and perfectly still while scientists recorded her brain activity.  

This unique approach to explore canine cognition led Berns to become a bestselling author with the publication of “How Dogs Love Us” in 2013. It is just one of many popular books by Berns, including, in 2022, “The Self Delusion: The New Neuroscience of How We Invent — and Reinvent — Our Identities.”  

It was his own reinvention, from city dweller to farmer, that led to Berns’ upcoming title, “Cowpuppy: An Unexpected Friendship and a Scientist’s Journey into the Secret World of Cows.” Set for publication by Harper Horizon on Aug. 20, the book describes Berns’ crash course in becoming a cattleman and his ongoing fascination with the interior world of cows.

“I originally got cows for biological help, to keep the grass down,” Berns explains. “But then my relationship with them turned into something more. I started seeing the world through a cow’s eyes. There’s a common misconception that cows are dumb animals, but that’s just because most people haven’t had the opportunity to interact with them. I decided it was time to set the record straight on cow brains.” 

His new lifestyle also inspired Berns to develop an undergraduate class to debut this fall: “Psychology of Sustainability.” 

“Living on a farm and trying to learn how to manage the environment makes you think differently,” he says. “It’s all about balancing energy cycles. Can we have an economic system that doesn’t depend on the endless growth of capitalism? I don’t know if it’s possible, but I do know that living sustainably requires a different mindset than endless consumerism.” 

Some of the class topics include economics; models of decision-making, attention and mindfulness; the social and health effects that animals have on humans; and the management of natural resources. 

“Today’s students are the generation that’s going to have to fix a lot of the environmental problems that we’ve created,” Berns says. “The class aims to help them foster solutions and refocus their attention on things that actually make them happy.” 

Berns' 85-acre farm consists of about 20 acres of pasture surrounded by woodlands and wetlands.

Before embarking on a tour of his 85-acre property, Berns advises his visitor to change into a pair of knee-high gumboots. “It’s muddy,” he says. “And there’s a lot of ticks this year.” 

Gus darts ahead as Berns sets off through the pine forest on his land, which rolls down toward a creek. The U.S. Forestry Service prepared a management plan for Berns to maintain the trees through selective logging and controlled burns of underbrush.

Berns squelches through the mud back up the hill where a workshop houses a tractor and no-till drill.

“One of the fundamental tenets of regenerative agriculture is don’t till up the soil,” he says. “Traditional seeding is a violent process that destroys the soil structure and makes the topsoil prone to erosion.” 

In contrast, metal disks on the no-till drill slice the soil and the plant residue, insert seeds and then tamp the soil and organic matter back down.  

Berns strives to provide fresh grass and other crops for his cows to graze on nearly year-round. In turn, the cows provide manure that improves the soil.

“I’ve become an expert on grass out of necessity,” Berns says, as he plucks a sprig from the ground. “This is ryegrass. It’s a cool season grass famed for its rapid growth.”

He balances the ecosystem through crop rotation. Daikon radish is known for deep taproots that penetrate the hardpan of the fields. Clover, a legume, can pull nitrogen out of the air and make it available to other plants. And nitrogen is like steroids for bermudagrass, which thrives in the warm season.

The tour continues past a small vegetable garden, then down to a barn and an open-air pen where around a dozen chickens keep nests when they are not free-ranging.

“We have two roosters right now, but they're beginning to fight, so one of them will likely go into a soup pot,” Berns says. “Living on a farm, you become really conscious of where your food comes from.”

Finally, Berns leads the way into a pasture and the main attraction: the herd of 10 miniature Zebu. The cattle breed originated in South Asia and is distinguished by droopy ears, a hump of fat on its shoulders and a dewlap — loose flesh hanging from the neck. The miniature variety reaches a maximum height of 3.5 feet at the withers.

The animals amble toward Berns, slowly enveloping him in a giant cow cuddle as he sinks to his knees in the grass.

Cows are "intelligent, emotional and loyally affectionate," Berns says.

“This is Ethel,” Berns says, as he rubs a grayish-white cow’s neck. “And this is Walker,” he adds, as he pats a calf the same color as Ethel, his mom.  

A brown calf named Cricket nuzzles Berns’ back. “Cricket here is getting jealous because I’m giving attention to Walker,” Berns explains. “I’m not feeding them anything. This is just for pets and lovin’.”

Berns kneels next to a full-grown, gray-dappled male and another of Ethel’s offspring.

“This is B.B., the number one cowpuppy. We have this little thing where he puts his head on my shoulder and gives me licks,” Berns says, grinning as B.B. slurps the side of his face. “That’s how he shows affection.”

In his book, Berns writes about how he forged a deep bond with his herd, as he learned each of their distinct personalities while helping them to give birth, grow and stay healthy. He senses a wide range of human emotions in them and finds their presence therapeutic.

He describes leaning against the hulk of a cow chewing its cud in the evenings while he marvels at the stars. “Whenever I felt the weight of life’s challenges, I sought out the cows,” Berns writes. “I often found myself drifting off into a meditative state after these sessions. I felt relaxed in a way that I hadn’t before.”

It probably goes without saying that none of Berns’ cows will ever wind up as hamburgers or steaks. And, yet, Berns is not a vegetarian. Instead, he advocates for more mindful — and minimal — consumption of meat.

“People have always eaten cows and they will continue to do so,” he says. “But cows should be managed in a more humane way to give them the best possible life, even if they are headed for the dinner table.”

Berns rubs the neck of Walker, a young member of the herd, as a calf named Cricket nudges him for attention. Both Walker and Cricket were born on the farm.

There are about 101 million cows in the United States, one for every three people, Berns notes. Ninety percent of these cows are destined for beef. Calves are separated from their mothers and raised on industrialized feedlots known as concentrated animal feeding operations, or CAFOs. The CAFOs, some of them teeming with more than 100,000 animals, are designed to fatten cows quickly so they can be slaughtered after they reach 12 months.

“Do industrialized feedlots and meat-packing plants care about the mental well-being of these animals? Probably not,” Berns says. “But I think that an increasing number of consumers are starting to care about the welfare of the animals that they eat.”

The farm life didn’t just turn Berns into a cow person. A self-described introvert, he has also become more of a people person.

“My wife won’t go to the farm store with me anymore because I end up staying there an hour or more talking to people. It’s like ‘Green Acres,’” he says, referring to the 1970s sitcom about a lawyer and his wife who leave Manhattan to become farmers in a rural area. 

“I have more friends here and know more people better than I ever did living in Atlanta,” Berns says. “I’ve been surprised at the common ground I’ve found with my neighbors. Fundamentally, what people care about is community and family and the natural resources that we have here. They want to get to know their neighbors and they look out for each other. I really like that. It’s not something that I’ve experienced anywhere else that I’ve lived.”

Berns dedicated his book to Ken Peek, a retired pastor, Vietnam War veteran and cattleman who is his closest neighbor.

“Before moving to the farm, I could not have imagined someone more different from me than Ken,” Berns writes.

After three years of Peek helping him learn the ropes of raising cattle and maintaining a healthy farm, Berns now considers Peek his best friend.

Whether human to human or human to cow, face-to-face contact is key to the quality of relationships, Berns says, an understanding that is eroding in a digital world.

“I don’t care how much texting or whatever else you do with your family and friends online. I don’t believe that it’s possible to have the depth of connection you can have from face-to-face interactions,” he says. “I’m going to ban phones in my Psychology of Sustainability class.”
