Characteristics of temporal fluctuations in the hyperpolarized state of the cortical slow oscillation [PDF]
, 2008 We present evidence for the hypothesis that transitions between the low- and high-firing states of the cortical slow oscillation correspond to neuronal phase transitions. By analyzing intracellular recordings of the membrane potential during the cortical

A continuum model for the dynamics of the phase transition from slow-wave sleep to REM sleep [PDF]
, 2010 Previous studies have shown that activated cortical states (awake and rapid eye-movement (REM) sleep), are associated with increased cholinergic input into the cerebral cortex.

PLoS ONE, 2014 Oscillations in electrical activity are a characteristic feature of many brain networks and display a wide variety of temporal patterns. A network may express a single oscillation frequency, alternate between two or more distinct frequencies, or ...

Oscillations Governed by the Incoherent Dynamics in Necroptotic Signaling
Frontiers in Physics, 2021 Emerging evidences have suggested that oscillation is important for the induction of cell death. However, whether and how oscillation behavior is involved and required for necroptosis remain elusive.

Dynamics of Coupled Adaptive Elements : Bursting and Intermittent Oscillations Generated by Frustration in Networks [PDF]
, 2009 Adaptation to environmental change is a common property of biological systems. Cells initially respond to external changes in the environment, but after some time, they regain their original state.

NECESSARY AND SUFFICIENT TAUBERIANCONDITIONS UNDER WHICH CONVERGENCEFOLLOWS FROM SUMMABILITY Ar,p
Проблемы анализа, 2021 In this paper, we introduce the summability method Ar,p and obtain necessary and sufficient Tauberian conditions under which the ordinary convergence of a sequence follows from itssummability Ar,p.

Reproducing Infra-Slow Oscillations with Dopaminergic Modulation [PDF]
Scientific Reports, 2017 AbstractIn the human brain, billions of neurons construct a neural network via synaptic connections. Neuronal excitation and inhibition are transmitted to other neurons through synapses via neurotransmitters. Dopamine is one of these neurotransmitters that plays a number of important roles.

Multiscale dynamics underlying neocortical slow oscillations [PDF]
, 2021 ABSTRACTSlow oscillations in the sleeping and anesthetized brain invariantly emerge as an alternation between Up (high firing) and Down (almost quiescent) states. In cortex, they occur simultaneously in cell assemblies in different layers and propagate as traveling waves, a concerted activity at multiple scales whose interplay and role is still under ...

Laminar-dependent effects of cortical state on auditory cortical spontaneous activity
Frontiers in Neural Circuits, 2012 Cortical circuits spontaneously generate coordinated activity even in the absence of external inputs. The character of this activity depends on cortical state.

Intrinsic Coupling between Gamma Oscillations, Neuronal Discharges, and Slow Cortical Oscillations during Human Slow-Wave Sleep [PDF]
The Journal of Neuroscience, 2010 In the first electrocorticograms, Richard [Caton (1877)][1] connected a mirror galvanometer to exposed rabbit brains and observed slow sleep-related fluctuations. Several decades later, [Loomis et al. (1937)][2] applied the then-fledgling technique of scalp EEG to classify sleep stages in humans,
