AI Agent Guides Needle in Mouse Brain Surgery Experiment

Artificial intelligence has taken a step into medical research following a reported experiment where an AI agent selected a treatment, identified a brain region, and operated a robotic machine to inject a gene therapy vector into a mouse with epilepsy.

According to a social media post by Gabriel Ocana-Santero, co-founder of biotechnology startup Exin Therapeutics, researchers provided the AI agent with 19 gene therapy options and a single objective: to reduce seizures in a mouse model of epilepsy.

How the Procedure Unfolded

The reported experiment involved several distinct stages combining artificial intelligence and human supervision:

• Treatment Selection: The AI analyzed the provided data and selected a gene therapy treatment intended to increase a chemical signal that calms excessive brain activity.
• Location Determination: Drawing information from three scientific research papers, the AI identified the target brain region for the injection.
• Robotic Operation: The AI drove a motorized stereotaxic rig, guiding a needle into the brain to inject 250 nanolitres of the treatment while monitoring the site through a camera.

Safety Controls and Human Oversight

The procedure was not fully autonomous. A human surgeon handled the initial skull opening and final wound closure. Additionally, a licensed veterinarian approved critical irreversible steps and held a physical emergency kill switch to stop the AI agent if necessary.

During the procedure, the AI reportedly refused to move the needle when it detected incorrect equipment positioning, declining a researcher's request to try again. The team later identified a machine calibration issue, indicating the AI may have flagged a genuine safety risk.

Practical Implications and Verification

While the researcher reported that the mouse recovered well, it remains unconfirmed whether the treatment actually reduced epileptic seizures. This experiment serves as an early-stage demonstration rather than an approved medical procedure.

Readers should note that this account is based on a public post by the researcher and requires independent scientific peer review and verification. Future developments can be tracked by looking for peer-reviewed studies from the researchers or independent laboratories working on automated laboratory procedures.
