"Research reveals that dogs’ and humans’ brain activity can synchronize when they gaze into each other’s eyes. Known as neural coupling, this phenomenon has been seen in interactions within species, but observing it between different species highlights the unique human-dog bond.

The study found that brain regions linked to attention and focus align more closely as the familiarity between dog and owner grows. Notably, dogs with a genetic mutation linked to neural connectivity struggled with synchronization, but with an experimental treatment, this effect could be enhanced. This research offers new insights into how humans and dogs build deeper, more connected relationships."
