An artificial intelligence could measure how much pain a lab mouse is in based on its grimaces, potentially aiding the development of pain-relieving drugs


A new artificial intelligence (AI) estimates how much pain a mouse is in by analyzing its facial expressions. Researchers hope the tool will give scientists a better understanding of how effective a pain-relieving drug is and increase the number of pain-related experiments they can analyze at once.

Many pain treatments are first tested in mice by assessing a rodent’s discomfort after administration of the drug. But this …
