Dog
The latest research results show that the caudate nucleus of the dog's brain that controls emotions is similar to the caudate nucleus of humans, so dogs are indeed Have emotions for people.
But before this, many people did not think that the interaction between dogs and their owners was a true expression of affection. Scientists currently agree that dogs have feelings for people because people raise and protect them.
Emory University researchers used MRI technology to observe changes in dog brains. It was found that when the dog owner feeds the dog something to eat, the dog's tail nucleus will undergo changes similar to those of humans.
The researchers said that their next step will be to observe changes in the tail nucleus of the dog's brain when strangers or robots feed the dog. If the dog responds when a stranger or robot feeds it, it means that the dog really shows emotions for food.
