What if we could read our dogs’ minds tomorrow? We are not there. But researchers are still giving us today, for the first time, a glimpse into how the canine brain reconstructs what it sees. Not offending our ego, our best friends seem to be more interested in the actions we do than our little ones!
Recently, scientists have learned to decode the human brain’s processing of visual stimuli. thanks for theartificial intelligenceartificial intelligence (IA) and toMRIMRI functional (fMRIfMRI). The latter, in fact, makes it possible to visualize the brain activity of conscious people. Combined with artificial intelligence, it allows access, in a way, to what the subject is looking at without having to ask him. very scientific method “Read minds”.
This is exactly why researchers want to test the technology on a small number of animals. Primates of course. But also dogs. Let’s finally understand how animals think. Neuroscientists from Emory University (USA) today publish the first results. Results that show how our best friend’s mind interprets what it sees.
This preliminary work has so far been performed only on two dogs. But two dogs are wide attentive. Practice beforehand to get into the scanner and stay still there, without having to be tied down. The researchers recorded functional magnetic resonance imaging (NMR) neurological data while the dogs in question watched the videos. Then they applied a machine learning algorithm to analyze the said data. And so they have succeeded, at least to some extent, in reconstructing the way dogs see the world.
The basic differences between dogs and humans
I wonder what those clips showed? Quite simply pictures of the daily life of a dog. Dogs receive rewards, sniff each other, play or walk on a leash. but also carscarsOr bicycles or cats or deer. And of course, humans hug a dog, eat it, or throw a ball at them. All time stamped by workbooks based on ” Things “ – a dog, a ball, a human – on the one hand, and in actions – smelling, playing and eating – on the other.
For comparison, two people participated in the same experiment. Specifically, the results obtained by researchers from Emory University point to significant differences in the functioning of the brain of humans and dogs. “We humans are very objective oriented”Gregory Burns, professor of psychology, said in a press release. “If there are ten times more nouns than verbs in English, it is probably because of our own obsession with naming things. On the other hand, dogs seem less interested in who or what they see and more interested in the action itself.”
An unsurprising result when we know that dogs have a slightly higher density of visual receptors designed to detect movementsmovements of humans. When you are an animal, you need to worry about what is happening in your environment, to avoid unpleasant surprises. Then work seems necessary.
