AI-Driven Neurosurgery
Exin Therapeutics, a biotech startup focusing on next-generation neurotherapeutics, claims it has successfully conducted brain surgery on a mouse using an AI agent. Its co-founder and CEO shared the procedure on social media, showing how the AI agent chose the gene therapy vector, dosage, and targeted brain region before driving the robotic arms to inject the medication.
The experiment involved providing a mouse model of epilepsy, access to a motorized surgery rig with cameras, and a specific therapeutic goal. The system derived coordinates from research literature, drove stereotaxic arms into the brain, and delivered small nanoliter volumes while monitoring the entry site through the rig camera.
Autonomous Decision Making
According to the startup, previous surgical robots relied entirely on human operators to determine the operation parameters while the hardware executed the commands. In this setup, the agent evaluated a spreadsheet of candidate therapies and determined the appropriate treatment coordinates independently.
Safety and Supervision
The team utilized Anthropic Sonnet alongside a motorized rig and a spreadsheet of 19 gene therapy vectors. A licensed veterinarian oversaw the operation, with mandatory approval steps required before the system could proceed with irreversible actions. An emergency stop button was also integrated to cut power to the rig motors instantly.
Human intervention was limited to performing the initial craniotomy to expose the brain, as the system was restricted from executing that phase. Certain safety parameters were hardcoded to prevent overrides by the agent, requiring manual code adjustments during the procedure.
Model Limitations
The startup initially tested a more advanced model, which refused to participate after detecting that it was being used for a biological experiment. Consequently, the team utilized Sonnet to successfully run the live procedure under human supervision.
This procedure marks an initial step toward integrating autonomous software agents directly into experimental laboratory workflows.
Ethical Considerations
Despite the successful recovery of the test subject, the experiment has renewed discussions surrounding the ethics and accountability of deploying automated decision-making in medical and surgical contexts.
