AI reveals that mice’s faces express a range of emotions — just like humans
AI has revealed that mice have a range of facial expressions that show they feel — offering fresh clues about how emotional responses arise in human brains. Scientists at the Max Planck Institute of Neurobiology in Germany made the discovery by recording the faces of lab mice when they were exposed to different stimuli, such as sweet flavors and electric shocks. The researchers then used machine learning algorithms to analyze how the rodents’ faces changed when they experienced different feelings. The software showed that their facial muscles would subtly shift as their emotions changed. Mice feeling pain pulled their ears…
