Dogs are known to be a man's best friend. They are known to be loyal and most importantly obey most of the order their master has to offer. The people usually train their dogs to perform various tricks on their command like sit-down, shake hand and roll over. But some researchers at Emory University have gone an extra length by teaching two dogs to jump inside an MRI machine and lay still.

The main motive of this training is to scan their brains in order to get some insights into the brain patterns while the dogs were awake and responsive. This would help decode the mental processes of the dogs. Although most dogs responds to human contact and expression, there is little information that is known of what goes in that mind of theirs. There are a lot of questions like what the dog is thinking, when his tail is wagging, or when his tongue is out the side of his mouth. So far the researchers has been able to deduce that a part of dog's brain lights up when they expects a treat.

The biggest hurdle in front of them was to make the dogs sit inside the MRI scanner while they are conscious, as the researchers wanted to find the patterns while they were responsive.
