Scientists from Konkuk University in South Korea found that interacting with dogs can increase brain waves in areas related to regulating stress and improving concentration. Research results published In the journal PLOS ONE.
To better understand how interaction with animals affects mood and cognitive skills, scientists asked 30 adult participants to do eight different activities with a well-trained dog. Volunteers took photos with the animal, played with it and offered various treats for a while.
It was noted that during the experiment, all participants wore special devices for electroencephalography (EEG), which examines the electrical activity of the brain during interaction with a dog.
The results showed that the relative strength of alpha band oscillations in the brain increased when participants played with the dog and walked with the dog, reflecting a state of relaxation and calm. In a healthy person, the alpha rhythm predominates in amplitude in the parietal, occipital, and sensorimotor cortex of the brain.
When brushing the dog’s fur, stroking it, or playing with the animal, the relative strength of beta interval oscillations increased, indicating an improvement in concentration. This rhythm is most strongly expressed in the frontal regions, but with various types of intense activity it sharply intensifies and spreads to other parts of the brain.
The study authors noted that their discovery provides valuable information about the therapeutic effects of human-animal interactions. The data obtained can be used in the future to develop new methods to combat anxiety and stress.
