Human gamma oscillations during slow wave sleep. [PDF]
PLoS ONE, 2012 Neocortical local field potentials have shown that gamma oscillations occur spontaneously during slow-wave sleep (SWS). At the macroscopic EEG level in the human brain, no evidences were reported so far.

Slow oscillations persist in pancreatic beta cells lacking phosphofructokinase M. [PDF]
Biophys J, 2022 Pulsatile insulin secretion by pancreatic beta cells is necessary for tight glucose control in the body. Glycolytic oscillations have been proposed as the mechanism for generating the electrical oscillations underlying pulsatile insulin secretion.

Respiration modulates sleep oscillations and memory reactivation in humans
Nature Communications, 2023 The beneficial effect of sleep on memory consolidation relies on the precise interplay of slow oscillations and spindles. However, whether these rhythms are orchestrated by an underlying pacemaker has remained elusive.

The human thalamus orchestrates neocortical oscillations during NREM sleep
Nature Communications, 2022 Slow oscillations, which are instrumental to memory consolidation, have been assumed to be solely generated in neocortex. Here, the authors show that the anterior thalamus might play a fundamental role in organizing slow oscillations in human sleep.

Effect of structuring on coronal loop oscillations [PDF]
, 2007 In this Thesis the theoretical understanding of oscillations in coronal structures is developed. In particular, coronal loops are modelled as magnetic slabs of plasma.

PLoS ONE, 2013 Slow oscillations are a hallmark of slow wave sleep. They provide a temporal framework for a variety of phasic events to occur and interact during sleep, including the expression of high-frequency oscillations and the discharge of neurons across the ...

Numerical continuation of canard orbits in slow-fast dynamical systems [PDF]
, 2009 A trajectory of a system with two clearly separated time scales generally consists of fast segments (or jumps) followed by slow segments where the trajectory follows an attracting part of a slow manifold. The switch back to fast dynamics typically occurs

Physiological Mechanisms and Significance of Intracranial B Waves
Frontiers in Neurology, 2022 ObjectiveRecently published studies have described slow spontaneous cerebral blood flow (CBF) and cerebrospinal fluid (CSF) oscillations measured by magnetic resonance imaging (MRI) as potential drivers of brain glymphatic flow, with a similar frequency ...

Coexistence of fast and slow gamma oscillations in one population of inhibitory spiking neurons
Physical Review Research, 2020 Oscillations are a hallmark of neural population activity in various brain regions with a spectrum covering a wide range of frequencies. Within this spectrum γ oscillations have received particular attention due to their ubiquitous nature and their ...
