OBJECTIVE It is well known that electroencephalograms (EEGs) show electrical silence in deep anesthesia as well as brain death. This is the first report on intracranial EEG changes in deep anesthesia. METHODS We developed a new direct brain monitoring system capable of recording intracranial EEGs. This study included 13 patients with head trauma or cerebrovascular accident under deep anesthesia. RESULTS The intracranial EEGs showed different patterns of wave activity in depth compared with… Expand
Effect of Propofol on Brain Electrical Activity in Cat Motor Cortex
TLDR
Propofol can cause reversible changes in the motor cortex of cat and the recovery time of field potential was less than the time of action potential, which indicates that field potential changes over time are reversible. Expand
Permutation entropy in intraoperative ECoG of brain tumour patients in awake tumour surgery– a robust parameter to separate consciousness from unconsciousness
TLDR
ECoG and a consecutive analysis of PeEn are feasible and suitable for the continuous surveillance of patients during awake craniotomies, and the analysis is not influenced by patients’ clinical characteristics. Expand
Cerebral cortical effects of desflurane in sheep: comparison with isoflurane, sevoflurane and enflurane
TLDR
In this study, the propensity of desflurane to induce cortical spikes is investigated and made a direct objective comparison with enfluranes, isoflurane, and sevofl Lurane. Expand
Monitoring approaches in general anesthesia: a survey.
TLDR
An overview of recent developments in the field of general anesthesia monitoring is given, showing that there is no one universal monitor applicable to all general anesthesia--each has its own characteristics and might be useful in particular clinical situations. Expand

Medical Management of Brain-Dead Organ Donors
TLDR
This review discusses how to identify brain-dead donors and describes the physiological changes that occur following brain death, and proposes recommendations for a treatment protocol to be developed in the future. Expand
A review of the criteria used to assess insensibility and death in hunted whales compared to other species.
TLDR
When death in whales is solely determined on the basis of the IWC criteria, which in practice are based on immobility, a significant proportion of animals will be recorded as being sensible and alive when they are actually unconscious and the time to death (TTD) will be overestimated. Expand
The humane collection of fetal bovine serum and possibilities for serum-free cell and tissue culture.
TLDR
Recommendations, including the establishment of a public database with information on cell types and their serum-free medium composition is proposed, are proposed to prevent fetuses from breathing air or killing them by an efficient method. Expand

Generation of scalp discharges in temporal lobe epilepsy as suggested by intraoperative electrocorticographic recordings
TLDR
It seems that, in temporal lobe epilepsy, scalp discharges originate from widespread ECoG discharges and tend to produce a stereotyped pattern on the scalp with largest amplitudes at the anterior temporal electrodes. Expand
The Electroencephalogram in Man Anesthetized with Forane
TLDR
Forane-induced EEG changes can be distinguished from those seen with other anesthetics by the maintenance of high-frequency activity at any level where EEG activity is present, and depth of anesthesia can be monitored with the EEG. Expand
COMPARISON OF SUBCORTICAL, CORTICAL AND SCALP ACTIVITY USING CHRONICALLY INDWELLING ELECTRODES IN MAN.
TLDR
Intracerebral recordings show that there is little field spread in brain tissue and that cerebral models with dipoles deep within the brain are not satisfactory and model experiments indicate that cortical areas of at least 6 sq cm must be involved in synchronous or near synchronous activity before the scalp EEG is observed, using standard working gains.

A Comparison of EEG Seizure Patterns Recorded with Surface and Depth Electrodes in Patients with Temporal Lobe Epilepsy
TLDR
Electro EEG seizure activity was found to be less likely to propagate to the surface for those records that were either unaccompanied by behavior changes or accompanied only by auras than forThose records accompanied by clinical seizures. Expand
Electroencephalographic Burst Suppression in Elderly and Young Patients Anesthetized with Isoflurane
TLDR
In elderly patients the EEG had both a greater proportion of total time in electrical silence and a greater number of isoelectric periods than in younger patients, demonstrating a discrete alteration with age in the central nervous system sensitivity to isoflurane. Expand
Combined depth and subdural electrode investigation in uncontrolled epilepsy
TLDR
Variable or simultaneous unilateral neocortical versus hippocampal temporal lobe seizure onset, determined by the combined study, was significantly correlated with less favorable seizure control after anteromedial temporal lobectomy and hippocampectomy. Expand
Depth electrode recording in patients undergoing corpus callosotomy for intractable epilepsy.
TLDR
6 patients undergoing anterior corpus callosotomy for intractable epilepsy have been studied with depth electroencephalography (EEG) to confirm the ability of depth EEG to demonstrate and identify lateralized, focal and often multifocal disturbances. Expand
