In humans, sleep occurs in cyclical patterns; in each cycle of 11-2 to 2 hr, the sleeper moves through four stages of sleep, from Stage 1 to Stage 4, and back again to Stage 1. In the first stage, low-frequency, low-amplitude theta waves characterize brain activity. The stage usually...
The stimulating part 28 gives stimuli to the human body at the wake-up timing. The wake-up assisting apparatus 1 can obtain brain waves using the electrode part 22 and precisely determines the sleep stage that indicates the degree of the user's sleep. Thus, the wake-up assisting apparatus ...
To look for changes in the slope and amplitude of LoWS leading up to IEDs, we first identified the minimum of the 0.5–4 Hz filtered signal in a 1 s window following LoWS onset (which was defined as the amplitude) and defined LoWS slope as the ratio between that amplitude and the...
Third stage also known as "deep sleep" – in this stage it's difficult to awaken, and if you forcibly wake up, you do not adjust immediately and often feel groggy and disoriented for several minutes. In this deepest stage of sleep, your brain waves are extremely slow. Blood flow is dir...

The team usedfunctional neuroimagingto scan the brains of three people as they slept. The participants'brain waveswere recorded withelectroencephalography(EEG). The team monitored electrical patterns in the brain waves, so that they could wake them up whenever the signals indicated that they had be...
AN INTEGRATIVE MODEL FOR SLEEP/WAKE REGULATION In recent years, various theoretical models have been proposed to explain how and where the brain integrates information and computes a decision whether to wake up or stay asleep. The flip/flop model (Saper et al, 2010), posits that mutually ...
