An AI Agent Just Operated on a Live Mouse Brain. Here’s What Actually Happened.

说明与用途

Exin Therapeutics 使用自主 AI 代理在小鼠大脑中进行基因治疗注射，但未公开 IACUC 批准，引发治理和安全问题。

问题

A biotech startup performed autonomous AI‑driven brain surgery on a mouse without prior institutional ethics approval, raising questions about governance and safety.

结果

The AI agent autonomously selected a GABA‑boosting gene therapy, injected it into the mouse’s lateral entorhinal cortex, and the mouse recovered. The experiment highlighted gaps in AI‑driven animal research oversight.

工作流

• 1. Connect AI agent to Arduino‑based stereotaxic rig via Exin software interface.
• 2. Provide agent with high‑level goal and spreadsheet of candidate gene‑therapy vectors.
• 3. Agent selects therapy, target region, and coordinates based on literature.
• 4. Agent instructs rig to inject 250 nl over 5 min while mouse is anesthetized.
• 5. Licensed veterinarian performs craniotomy, monitors surgery, and closes wound.
• 6. Human approvals required for each irreversible command; emergency stop available.
• 7. Post‑procedure monitoring of behavior and brain activity planned.
• 8. Technical report to be published.
• 9. Follow‑up experiments with other AI models performed.
• 10. Discussion of ethics oversight and regulatory implications ensued.

证据

The team connected an AI agent to a custom-built, Arduino-based motorized stereotaxic rig, a device used in neuroscience to hold a small animal’s head still and guide a needle to a precise location in the brain.

The agent was given a single high-level goal: reduce tonic‑clonic seizures in a mouse model of epilepsy.

来源

The agent injected 250 nanoliters of the therapy over five minutes while the mouse was anesthetized. Ocana‑Santero reported that the mouse recovered well afterward.

来源

Exin was not running an unsupervised robot surgery. A licensed veterinarian performed the craniotomy, the initial opening in the skull, and closed the wound at the end.

As of the time of reporting, no public ethics approval record for the Exin experiment has been published.
