  "account": "A compact forehead patch, akin to a Band-Aid, can now effectively influence brain signals to enhance deep sleep, according to a report. William Coon, a sleep scientist at the Johns Hopkins Applied Physics Laboratory, has developed this at-home wearable device that listens to brain activity and employs neurostimulation techniques to optimize sleep. Coon describes the device as tailoring sleep to be a controllable biological system, drawing parallels to AI models that analyze language signals. The researchers trained an AI model on more than 11,000 overnight recordings from a public archive, enabling it to classify sleep stages automatically with accuracy comparable to human experts. The patch delivers interventions, referred to as \"levers,\" throughout a single night. One lever involves auditory clicks timed to encourage the production of slow-wave sleep waves, while another lever lowers body temperature using a cooling mattress system. Early pilot data indicate that combining these levers yields a greater boost in slow-wave sleep than using either individually. Coon emphasizes the potential of this technology to meaningfully alter brain function during sleep, highlighting the link between deep sleep and cognitive health. The researchers are collaborating with clinical experts to further develop the technology and conduct a multiyear clinical study.",
  "summary": "A patch the size of a Band-Aid, stuck to your forehead, can now do something no traditional sleep study or fitness tracker can: nudge your brain toward a better night's sleep. William Coon, a sleep scientist at the Johns Hopkins Applied Physics Laboratory, has built a wearable device, meant to be used at home, that listens to brain activity and uses neurostimulation and other techniques to…",
