Summary:

- The article discusses a study that examined the changes in brain waves when people pet dogs. The study found that petting a dog triggers the release of oxytocin, a hormone associated with social bonding and positive emotions, in both the human and the dog.

- The study used electroencephalography (EEG) to measure the brain activity of participants while they petted dogs. The results showed that petting a dog led to increased alpha and beta brain waves, which are associated with relaxation and positive emotions.

- The findings suggest that the act of petting a dog can have a calming and therapeutic effect on both the human and the animal, and could have implications for the use of animal-assisted therapy in various settings, such as healthcare and mental health treatment.
