"When Emory University neuroscientist Gregory Berns and his wife decided to venture into sustainable farming in rural Georgia, they knew that cows were a key part of a successful operation. But that was where his knowledge of cattle ended. As Berns and his small herd of three miniature zebus acclimated to each other and Berns received a crash course in being a cattleman, he turned his powers of scientific observation and innovation on his new charges. This wasn't the first time he'd studied animals through the lens of neuroscience; years earlier, Berns had applied his knowledge to man's best friend, resulting in two books and important advances in how we understand dogs' thoughts and emotions. Now it was time to see what he--and all of us--could discover about the interior worlds of cows."-- From publisher's description.
