Cross-approximate entropy of cortical local field potentials quantifies effects of anesthesia - a pilot study in rats

open access: yesBMC Neuroscience, 2010
Background Anesthetics dose-dependently shift electroencephalographic (EEG) activity towards high-amplitude, slow rhythms, indicative of a synchronization of neuronal activity in thalamocortical networks. Additionally, they uncouple brain areas in higher

What can a mean-field model tell us about the dynamics of the cortex? [PDF]

open access: yes, 2010
In this chapter we examine the dynamical behavior of a spatially homogeneous two-dimensional model of the cortex that incorporates membrane potential, synaptic flux rates and long- and short-range synaptic input, in two spatial dimensions, using ...

The effect of anaesthetics on the properties of a lipid membrane in the biologically relevant phase: A computer simulation study [PDF]

open access: yes, 2015
Molecular dynamics simulations of the fully hydrated neat dipalmitoylphosphatidylcholine (DPPC) membrane as well as DPPC membranes containing four different general anaesthetic molecules, namely chloroform, halothane, diethyl ether and enflurane, have ...

Comparison of regional blood flow values measured by radioactive and fluorescent microspheres [PDF]

open access: yes, 2002
Fluorescent microspheres (FM) have become an attractive alternative to radioactive microspheres (RM) for the measurement of regional blood flow (RBF). The aim of the present study was to investigate the comparability of both methods by measuring RBF with

MAC-AWAKE OF ISOFLURANE, ENFLURANE AND HALOTHANE EVALUATED BY SLOW AND FAST ALVEOLAR WASHOUT [PDF]

open access: yes, 2017
End-tidal anaesthetic concentrations at first eye opening in response to a verbal command during recovery from anaesthesia (MAC-awake), were measured for isoflurane (n = 16), enflurane (n = 16) and halothane (n = 14). MAC-awake was measured during either
