.- The special bond between man and his best friend, the dog lies on a hormonal process that is activated when viewed and is similar to that between a mother and her son, according to a study published today in the journal “Science”.

A research team led by Miho Nagasawa, Japanese Azabu University, has seen how the look between the dog and its owner fires in both oxytocin levels in the brain , a hormone related sexual patterns and paternal and maternal behavior.

Oxytocin also acts as a neurotransmitter in the brain and is considered to have an important role in the recognition and establishment of social bonds and the formation of trust relationships between people.

To conduct this research, scientists put in a room with several dogs with their owners and documented every interaction between them for 30 minutes.

Then, measured levels of oxytocin both the urine of dogs as that of their owners and found that sustained eye contact between them elevated levels hormone in the brains of both .

In a second experiment, the researchers sprayed oxytocin in the noses of some dogs and placed in a room with their owners and some unknown.

The animals responded i ncrementando time watching their owners and, after half an hour, oxytocin levels rose by owners of dogs treated.

As the wolves do not have this same response, even when reared by humans, researchers suggest in their study that this mechanism connection between man and the dog was forged in the course of domestication of these animals .

“The same connection mechanism, based on the increase of oxytocin to look, it strengthens the emotional bonds between mothers and their children, also helps regulate the relationship between dogs and their owners” concludes the investigation. EFE
