An artificial intelligence could gauge how much pain a laboratory 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 analysing its facial grimaces. Researchers hope the tool will give scientists a better understanding of how effective a pain-relief drug is and increase the number of pain-related experiments they can analyse at one time.

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