A Better Mouse Pain Picture

Loyal readers will recall Friday’s post in which Stephen Greene, professor in anesthesiology at WSU’s College of Veterinary Medicine, commented on the first study of how a non-human animal’s face can express pain. Its publisher, Nature Methods, has kindly granted us permission to show a great set of pictures showing the “mouse grimace scale” that may some day be put to use in drug testing and veterinary care.

The "mouse grimace scale," according to the authors, "may provide insight into the subjective pain experience of mice."
