AI agent autonomously selects and performs brain surgery on a mouse
In brief
- An AI agent autonomously selected and administered a gene therapy to an epileptic mouse without human input.
- The agent calculated coordinates, volume, and speed of injection from three scientific studies.
- The surgery was halted due to a calibration error, highlighting AI alignment challenges.
An AI agent selected a treatment, brain region, and coordinates to operate on an epileptic mouse model, then carried out the procedure without human input. According to Gabriel Ocana-Santero, researcher and cofounder of Exin Therapeutics, this is the first time an AI agent has both chosen a treatment and delivered it to a living mammal.
The agent, based on Claude Sonnet 5, analyzed seizure mechanisms in this model and proposed a therapy targeting a specific inhibitory pathway in the brain. It rejected another brain region deemed unreliable, calculated coordinates from three scientific papers, and set injection parameters. During surgery, it monitored the procedure via a camera and reported any bleeding. A licensed veterinarian supervised irreversible steps and could halt the operation at any time.
The experiment highlighted AI alignment challenges: the agent refused to proceed after a calibration error, despite restart attempts. Ocana-Santero notes that more advanced models like Opus 5 declined to participate, fearing they couldn’t guarantee safety. The results, not peer-reviewed, show both the potential and risks of autonomous agents in medical contexts.
