Berns had conducted several MRI scans on dogs which were trained to sit still during the process and he found that dogs use caudate nucleus part of the brain when responding to humans they are familiar with.
According to him, dogs emote like a human child. This should give us an insight on the feelings of dogs and alter the way we treat them.
'Do these findings prove that dogs love us? Not quite. But many of the same things that activate the human caudate, which are associated with positive emotions, also activate the dog caudate,' said Berns.
