The system learned to suppress pathological alpha-beta oscillations by 45.2% compared to continuous stimulation, while reducing the electrical charge delivered by 80%. The trained policy was then compressed onto the SynSense XyloAudio 3 neuromorphic processor, which runs inference at 0.52 mW — 28.1 times more efficient than an equivalent neural network on standard edge hardware.\n\nBattery life is the central constraint of any implantable medical device; a dead stimulator means a surgery to replace it. Most neuromorphic computing research stops at making the controller efficient, but this work points out that once inference is cheap enough, the stimulation pulses themselves become the dominant energy draw. Folding actuator energy directly into the reinforcement learning reward is a straightforward idea that the field has largely ignored.\n\nDeep brain stimulation is already a mature therapy, but its hardware is notoriously power-hungry. If this approach holds up outside a simulation, it could meaningfully extend device lifetimes — which would matter a great deal to the people who have these things implanted in their skulls.","[\"neuroscience\",\"ai\",\"hardware\",\"medical-devices\"]","2026-06-30T04:00:00.000Z","2026-06-30T09:00:24.868Z","2026-06-30T09:00:28.609Z","published",null,[],"ai",[26,24,27,28],"neuroscience","hardware","medical-devices",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2606.28600",0,{"sections":35},[36,40,45,50,55,59,64,69,74,79,84,88,93,98],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":56,"slug":27,"count":57,"latest_published_at":58},"Hardware",122,"2026-07-14T19:46:26.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":63},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":65,"slug":66,"count":67,"latest_published_at":68},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":70,"slug":71,"count":72,"latest_published_at":73},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":75,"slug":76,"count":77,"latest_published_at":78},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":80,"slug":81,"count":82,"latest_published_at":83},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":85,"slug":86,"count":82,"latest_published_at":87},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
