Signatures of Thalamocortical Alpha Oscillations and Synchronization With Increased Anesthetic Depths Under Isoflurane

open access: yesFrontiers in Pharmacology, 2022
Background: Electroencephalography (EEG) recordings under propofol exhibit an increase in slow and alpha oscillation power and dose-dependent phase–amplitude coupling (PAC), which underlie GABAA potentiation and the central role of thalamocortical ...

A novel slow (< 1 Hz) oscillation of neocortical neurons in vivo: depolarizing and hyperpolarizing components

open access: yesJournal of Neuroscience, 1993
We describe a novel slow oscillation in intracellular recordings from cortical association areas 5 and 7, motor areas 4 and 6, and visual areas 17 and 18 of cats under various anesthetics.

Nitrous oxide-induced slow and delta oscillations

open access: yesClinical Neurophysiology, 2016
Switching from maintenance of general anesthesia with an ether anesthetic to maintenance with high-dose (concentration >50% and total gas flow rate >4 liters per minute) nitrous oxide is a common practice used to facilitate emergence from general anesthesia.

Synchronization Properties of Slow Cortical Oscillations [PDF]

open access: yesProgress of Theoretical Physics Supplement, 2006
During slow-wave sleep, the brain shows slow oscillatory activity with remarkable long-range synchrony. Intracellular recordings show that the slow oscillation consists of two phases: an up state and a down state. Deriving the phase-response function of simplified neuronal systems, we examine the synchronization properties on slow oscillations between ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

The effectiveness of auditory stimulation in sleep varies with thalamocortical spindle phase

open access: yesNeuroImage
Slow oscillations and sleep spindles are neural events that both occur during non-rapid eye movement sleep and are implicated in sleep-dependent memory consolidation.

On slow oscillation and nonoscillation in retarded equations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1979
Sufficient conditions have been found to ensure that all oscillatory solutions of (r(t)y′(t))′+a(t)y(t−ξ(t))=f(t) are slowly oscillating. This behaviour is further linked to nonoscillation.

Attribution and Causality Analyses of Regional Climate Variability

open access: yesLand, 2023
A two-step attribution and causality diagnostic is designed by employing singular spectrum analysis to unfold the attributed climate time series into a trajectory matrix and then subjected to an empirical orthogonal function analysis to identify the ...

Tunable Oscillations in the Purkinje Neuron

open access: yes, 2011
In this paper, we study the dynamics of slow oscillations in Purkinje neurons in vitro, and derive a strong association with a forced parametric oscillator model.

Observations of apparent superslow wave propagation in solar prominences [PDF]

open access: yes, 2017
Phase mixing of standing continuum Alfv\'en waves and/or continuum slow waves in atmospheric magnetic structures such as coronal arcades can create the apparent effect of a wave propagating across the magnetic field.
