We finally figured out how to switch off brain seizures by treating the brain like a glitchy electrical circuit.

The Takeaway
Current brain implants fail to stop seizures in 82% of patients because they don't account for the complex physics of how neural storms spread. This new approach uses 'passivity theory' to prove that specific electrical feedback can force chaotic brain activity back into a stable state, potentially offering a path to total seizure control.
From the abstract
Recent advances in neurotechnologies and decades of scientific and clinical research have made closed-loop electrical neuromodulation one of the most promising avenues for the treatment of drug-resistant epilepsy (DRE), a condition that affects over 15 million individuals globally. Yet, with the existing clinical state of the art, only 18% of patients with DRE who undergo closed-loop neuromodulation become seizure-free. In a recent study, we demonstrated that a simple proportional feedback polic
