and the more frequent appearance of generalized angiopathy in patients with temporal slow activity (79.4%) in comparison with the remaining patients without temporal slow activity (55%) support the view of the dependence of this electrographic element on the circulatory disturbances of the brain, whi...
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...
Spiking activity across the human brain is tightly locked to EEG slow waves Most slow waves and spindles are local and occur separately in specific region... Y Nir,R Staba,T Andrillon,... - 《Neuron》 被引量: 736发表: 2011年 Regional Slow Waves and Spindles in Human Sleep Summary The ...
Spindle waves are a prototypical example of synchronized oscillations, a common feature of neuronal activity in thalamic and cortical systems in sleeping a... MV Krosigk,T Bal,DA Mccormick - 《Science》 被引量: 1412发表: 1993年 All-night dynamics of the human sleep EEG SUMMARY The dynamic...
In such a view, the correlation dimension was calculated for the profiles of the EEG slow-wave activity during sleep obtained from 7 young normal controls and in their corresponding artificial stochastic signals. It was possible to evaluate the complexity of all the real profiles which exhibited ...
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...
Whether and how slow wave activity (SWA) and the underlying membrane potential UP and DOWN states initiate mechanisms that augment memory functions in humans are not fully understood. Here authors used multineuron patch-clamp in alive human brain tissue, resected during neurosurgeries, to show that...
- 《Human Brain Mapping》 被引量: 52发表: 2015年 Effect of sedative and hypnotic doses of propofol on the EEG activity of patients with or without a history of seizure disorders. Propofol is alleged to possess both pro- and anticonvulsant properties, leading to controversy regarding its use ...
The resting brain is associated with significant intrinsic activity fluctuations, such as the correlated low-frequency (LF) blood oxygen level-dependent (B... DL Schacter - 《Cerebral Cortex》 被引量: 301发表: 2009年 Spatiotemporal dynamics of the brain at rest — Exploring EEG microstates as ...
Therefore, it has become current practice to name this EEG activity Rhythmic Slow Activity (RSA), in order to avoid the term theta rhythm, which does not cover the entire frequency range within which the hippocampal EEG of lower animals may fall. Several reviews on RSA, particularly in ...
