For the first time, Chinese researchers have uncovered evidence suggesting that the brains of humans and dogs may synchronize when they interact. This discovery could explain the deep connection people often feel when gazing into a dog’s big, soulful eyes, indicating a potential neurological bond between the two species.
Previous studies have shown that when humans engage with one another, key brain regions tend to sync up. However, this new study marks the first time that such brain synchronization has been observed between humans and dogs.
How the study revealed brain synchronization
To measure brain activity, researchers placed electrodes on the skulls of both humans and dogs. In the trial, 10 young beagles were paired with unfamiliar humans, and the pairs spent five days getting to know each other. During the experiments, the humans and dogs engaged in non-verbal communication, sitting in the same room without directly interacting.
The study, led by biologist Wei Ren from the Chinese Academy of Sciences, revealed that brain activity between humans and dogs, particularly in the frontal and parietal regions, increased dramatically when they gazed into each other’s eyes. The researchers also observed synchronization patterns when humans petted the dogs, with stronger synchrony occurring in the parietal brain region.
When the participants gazed into the dogs’ eyes, the inter-brain activity deepened. Using a specialized mathematical algorithm, the researchers determined that it was the human brain initiating this rhythmic neural connection. Over time, the synchronization between the human-dog pairs grew, indicating a deepening bond between them.
This study highlights the possibility of humans and dogs forming a connection at a neurological level, shedding new light on the unique bond between the two species.
