Using MRI
technology, scientists at Emory University ( Atlanta ,
USA ) set out
to determine how dogs' brains work, and they discovered that dogs experience
emotions in a way comparable to humans.
For two years researcher
Berns and his colleagues have trained dogs to enter an MRI scanner while awake
and unrestrained. Typically, animals are anesthetized so they won't move during
a scan, but you can't study brain functions like perception and emotion when an
animal is asleep.
Another reason
Berns chose not to anesthetize his canine participants is because he says
wanted to treat the dogs like people.
All the dogs in
the study have consent forms signed by their owners, and only positive training
methods are used to prepare the animals for the MRI.
Berns' own dog,
Callie, was the first dog to have her brain scanned. With the help of a dog
trainer, Berns taught Callie to enter an MRI simulator.
Callie learned to
enter the tube, place her head in a chin rest and sit still while wearing
earmuffs to protect her ears from the machine's noise.
After a few
months of training, Callie was ready for her first MRI, and Berns and his
colleagues got their first maps of canine brain activity.
Other owners soon
volunteered their dogs for research, and Berns has now scanned more than a
dozen of their brains. The more data he gathers, the more he's convinced that
dogs aren't that different from us.
The canine brain
maps showed Berns that dogs use a region of the brain known as the caudate
nucleus in a similar way to humans.
These findings
don’t necessarily mean that our dogs love us, but because many of the same
things activate both the human caudate and the dog caudate, neuroscientists say
this could be an indication of canine emotions.

What's their emotional IQ?
This is open to interpretation by the owners.
