Slow wave sleep, also known as the 'orthodox phase' or non-rapid eye movement (NREM) sleep, is a phase characterized by slow brain waves on EEG, reduced muscle activity, regular breathing and heart rate, and minimal dreaming. It is considered the forebrain phase of sleep influenced by the...
Such recordings are usually made with macroelectrodes inbedded within nervous tissue, or on the surface of the skull or brain. Even though such recordings were first reported 45 years ago by Berger, contemporary understanding of their physiological basis is remarkedly undeveloped. It is generally ...

Slow-wave sleep (SWS) refers to phase 3 sleep, which is the deepest phase of non-rapid eye movement (NREM) sleep, and is characterized by delta waves (measured by EEG). Dreaming and sleepwalking can occur during SWS. SWS is thought to be important for memory consolidation. ...
humans under sleep pressure undergoing scalp EEG recordings41, stimulation of cortical regions surrounding focal brain injury24, or thermocoagulation of clinically-defined brain areas25. However, typical slow waves with an associated neuronal down-state have not previously been described in awake humans,...
delta EEG frequencysleepthalamo‐cortical loopAutism is a developmental disorder with a neurobiological aetiology. Studies of the autistic brain identified atypical developmental trajectories that may lead to an impaired capacity to modulate electroencephalogram activity during sleep. We assessed the topography...
Changes in EEG delta-activity are widely used as proxy of sleep propensity. Here the authors demonstrate in mice and humans the presence of two types of delta-waves, only one of which reports on prior sleep-wake history with dynamics denoting a wake-inertia process accompanying deepest non-rapi...
A special type of delta waves with a duration of 1–3 sec which, because of their saw-tooth or zed shape in the EEG, we have named 'zeta waves' has been described. They occur particularly in cases with rather severe brain lesions, usually with an acute or subacute onset and a space ...
Slow waves (SWs) were automatically detected on each scalp channel based on previously established criteria (Menicucci et al., 2009). After pre-filtering NREM sleep EEG data to 0.5–4 Hz, slow waves were defined as negative deflections of a duration between 200 and 1000 msec and a minimum ...
Head CT or magnetic resonance imaging revealed brain dysplasia, encephalomalacia and abnormal white matter signal, and electroencephalography displayedslow waveor epileptiform activity. The appearances of abnormal EEG were mainlyslow waveand local epileptiform discharge. ...
