Scientists decode mouse facial expressions Researchers have used a machine-learning algorithm to decipher the seemingly inscrutable facial expressions of laboratory mice. For example, a mouse experiencing pleasure pulls its nose down towards its mouth, and pulls its ears and jaw forwards. By contrast, when in pain, it pulls back its ears and bulks out its cheeks, and sometimes squints. The work “is an important first step” in understanding some of the mysterious aspects of emotions and how they manifest in the brain, says neuroscientist David Anderson.
