Closed-loop externally powered electrical cortical stimulations (xcs)

The present disclosure relates dynamic closed-loop neuromodulation techniques to induce an externally powered electrical cortical stimulation (XCS) configured for various applications by leveraging real-time neural data of a subject. The neural data may be collected by one or more neuromodulation devices, placed epidurally through surgical implantation into a skull. A brain state may be estimated by processing the neural data via analytical techniques. Based on the predicted brain state, a set of stimulation parameters, associated with the XCS for a cortical region, may be determined. This determination may rely on a state transition model, configured to learn how brain transitions from one brain state to another based on the ongoing neural activity. The brain responses to applied XCS may be monitored from the neural data collected in real-time. Based on the monitoring, one or more stimulation parameters may be dynamically adjusted for each XCS in a closed loop.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B5/375, A61B5/4064, A61B5/4836, A61N1/0531, A61N1/3606). The claims define what a patent protects, and they are not read here.

Interface and electrodes

Everything downstream works with what the contacts pick up. Their number, size and distance from the neurons set the ceiling on the signal. The problem behind it: more contacts, closer to neurons, that still record after years in tissue that reacts to them.

Stimulation

Restoring sensation, sight or movement needs information going in, and a therapy that adapts needs to sense and stimulate at once. The problem behind it: evoking a precise, stable effect without damaging tissue or electrodes, and without blinding the recording.

Why the layer matters to the field, not a judgement of this filing. A patent family shows that protection was sought. It does not show that the technology was built, is used in a product, or works in people. The whole stack
