Atlanta: Dogs have been domesticated as far back as 32,000 years ago. According to Euromonitor International, India is the fastest growing global pet market. If we talk about the US dogs are a fixture in almost 50% American household. Have you ever observed keenly the activities of your pet, from the way they thump their tails, invade our laps and steal our pillows, it certainly seems like they love us back. Since these pets can’t communicate with us, what’s going on inside their furry heads, is still a matter of curiosity?
Scientist studied the dog’s brain
The relationship between dogs and humans is so deep that they easily adapt to our houses. Obey our orders, but at times bypassing those order, they start lickings with their tongue. Researchers at Emory University in Atlanta, USA, scanned their brains to know about this behaviour of dogs. The information that came out from research reveals the behaviour of dogs.
Dog brain-based evidence
The most direct dog brain-based evidence that they are hopelessly devoted to humans comes from a recent neuroimaging study about odour processing in the dog brain.
Scientists found a cordate nucleus found in the dog’s brain, this helps the dogs recognize the smell of their owner’s body and decide who is close to them and who is not.
- Scientists trained dogs to lie still in an MRI machine and used MRI (functional magnetic resonance imaging) to measure their neural responses to the smell of people and dogs, familiar and unknown.
- Dogs navigate the world through their noses, the way they process smell offers a lot of potential insight into social behaviour.
- Dog owners’ aroma actually sparked activation in the “reward centre” of their brains, called the caudate nucleus.
- Of all the smells to take in, dogs actually prioritized the hint of humans over anything or anyone else
