Dogs aren't hardwired to care about human faces, a new study has found, and there's no area in their brain designed to distinguish between the back or front of someone's head. Researchers measured brain activity in dogs and humans as they showed them videos of faces and backs of heads, a press release from Eötvös Loránd University, in Hungary, said. While faces are hugely important for visual communication in humans, the same can't be said for our canine companions. Experiments involving functional magnetic resonance imaging on 20 dogs were carried out at Eötvös Loránd University and the National Autonomous University of México, Querétaro, Mexico, two of very few facilities that can scan dogs' brains when they are awake and unrestrained. Results revealed large dedicated neural networks in human brains are used to differentiate faces from non-faces.
There are more than 7,000 languages in the world, a third of which have fewer than 1,000 people who continue to speak them. In southwestern Mexico, Microsoft is engaged as one of the community partners in efforts to preserve languages spoken in the region, specifically Yucatec Maya and Queretaro Otomi. By using AI, Microsoft has helped to protect endangered languages.
