Gabriel Ocana-Santero says an AI agent performed brain injections on epileptic mice

AI summary

Gabriel Ocana-Santero says an AI agent performed brain surgery on an epileptic mouse model: it selected a drug from 19 gene therapy vectors, chose the brain region, and derived coordinates from three papers, then drove a stereotactic arm to inject 250 nanoliters into the brain while monitoring via the device's camera whether there was bleeding at the needle entry site. Every irreversible step was overseen by a licensed veterinarian, who also held a physical emergency stop switch capable of halting the agent. The author says a long post will follow explaining what decisions the agent made, what it saw, and the moment it refused his intervention.
