The study uses functional Magnetic Resonance Imaging (fMRI) to scan the dogs' brains while they're shown different stimuli. Results from the first study will be published by the Public Library of Science, where the dogs were shown hand signals from their owners. 'We hope this opens up a whole new door for understanding canine cognition and inter-species communication. We want to understand the dog-human relationship, from the dog's perspective,' said Gregory Berns, director of the Emory Center for Neuropolicy and lead researcher of the dog project."
