Learning Sleep Stages from Radio Signals: A Conditional Adversarial Architecture
Mingmin Zhao (1) Shichao Yue (1) Dina Katabi (1) Tommi Jaakkola (1) Matt Bianchi (2) 1Massachusetts Institute of Technology 2Massachusetts General Hospital Overview: RF-Sleep learns to predict sleep stages from radio measurements without any attached sensors on subjects. We introduce a new predictive model that combines convolutional and recurrent neural networks to extract sleep-specific subject-invariant features from RF signals and capture the temporal progression of sleep. A key innovation underlying our approach is a modified adversarial training regime that discards extraneous information specific to individuals or measurement conditions, while retaining all information relevant to the …
Why Do I Wake Up Confused and Disorientated?
Published on August 12, 2017 | SleepReviewMag.com The Australian Broadcasting Corporation takes a look at why we sometimes wake up feeling very confused. Professor Lack said while there hadn’t been much research around the phenomenon, the body’s “rollercoaster” sleep cycle was probably to blame for feelings of confusion and disorientation. “Our sleep is like a rollercoaster going through 90 minutes of sleep cycles, starting in deep sleep and then light sleep … going across the night,” he said. “That deep sleep stage is the period where the conscious part of the brain — the upper part of the brain — …
Sleep is ‘like a rollercoaster’ which may contribute to waking up confused
BY ISABEL DAYMAN | SAT 12 AUG 2017, 2:45 PM AEST | Abc.net.au Have you ever woken up not knowing where you are? Do you wake up feeling confused or panicked, unsure of how you got there or how long you’ve been asleep for? Sleep expert Emeritus Professor Leon Lack, from Flinders University, explains what causes the strange sensations we experience when waking up. Why do I wake up confused and disorientated? Professor Lack said while there hadn’t been much research around the phenomenon, the body’s “rollercoaster” sleep cycle was probably to blame for feelings of confusion and disorientation. “Our …
What is deep sleep and how much of it should you be getting?
Oliver Wheaton for Metro.co.uk | Thursday 3 Aug 2017 2:07 pm | Metro.co.uk There are several different stages of sleeping, but the one which is most important to the body is deep sleep. In the modern age with our hectic lives and constant stimuli, people are getting less and less deep sleep, which can be having an affect on our health. What is deep sleep? Sleep researchers generally divide sleep up into five stages. Stages one and two are ‘light sleep’, stages three and four are ‘deep sleep’, while stage five is REM. Light sleep occurs when you first nod …
REM vs. Non-REM Sleep: The Stages of Sleep
By Cari Nierenberg, Live Science Contributor | July 19, 2017 11:19pm ET | LiveScience.com Scientists once thought that sleep was a passive state, a time when a person’s brain and body shut down for the night to rest and recover. But now, researchers know that sleep is a highly active time, a period during which the brain and some physiological processes may be hard at work. For example, some hormones involved in growth in children, cell repair or digestion are boosted during sleep. Brain pathways involved in learning and memory also increase, according to the National Institutes of Health (NIH). …
