Disease relevance of Electroencephalography


Psychiatry related information on Electroencephalography

  • Oral glutamine challenge in cirrhotics pre- and post-liver transplantation: a psychometric and analyzed EEG study [5].
  • After the sleep deprivation, SWA was increased, but the changes in EEG power density and SWA were more prominent and lasted longer in the PrP-null mice [6].
  • These results demonstrate that noradrenaline and serotonin exert differential modulatory effects on EEG activity through the basal forebrain, the one facilitating gamma activity and eliciting waking and the other diminishing gamma activity and not significantly affecting slow wave sleep [7].
  • Posttransplantation, there were no significant changes in blood ammonia, analyzed EEG, or choice reaction time in response to oral glutamine challenge (six patients) [5].
  • Type II status involved incessant exploratory behaviors, single EEG discharges, and the additional activation of the basal amygdaloid nucleus, some of its efferent projections, and parts of the olfactory cortex [8].

High impact information on Electroencephalography


Chemical compound and disease context of Electroencephalography


Biological context of Electroencephalography

  • Measures of skin resistance, heart rate, respiration, autonomic orienting responses, resting EEG, EEG alpha and theta frequencies, sleep-scored EEG, averaged evoked responses, and subjective experience were employed [18].
  • To determine whether the increased histamine levels in the brain of rats with portacaval anastomosis (PCA) are associated with the development of sleep disturbances during the light phase, the neocortical slow-wave activity of PCA-operated rats was examined with electroencephalography (EEG) 1 month and 6 months after the surgery [19].
  • Juvenile myoclonic epilepsy and the EEG trait segregated as an autosomal dominant trait with 70% penetrance [20].
  • Domoic acid (0.6 mg/kg) was injected intravenously through the caudal vein in pregnant female mice on the 13th day of gestation and EEG was monitored in the developing progeny during postnatal days 10-30 [21].
  • The amplitude of the late positive component of the event-related potential was larger in high-ability subjects, and the frontal midline theta component of the EEG signal was also selectively enhanced in this group under conditions of sustained performance and high working memory load [22].

Anatomical context of Electroencephalography

  • In addition, the possible transducing mechanisms coupling IL-2 receptor stimulation and the electroencephalogram (EEG) spectrum power responses elicited from the locus coeruleus seem to involve stimulation of specific receptors coupled to adenylate cyclase through a Gi protein [23].
  • These findings suggest that a single pathophysiological process accounts for unitemporal and some bitemporal epilepsy, but that independent onset of seizures from each temporal lobe detected by depth EEG may also indicate extratemporal foci [24].
  • In the present study, cells were recorded in the basal forebrain in association with cortical EEG activity in urethane-anesthetized rats, and their discharge was examined during EEG irregular slow activity and during stimulation-induced cortical activation, characterized by rhythmic slow (theta) and high-frequency (gamma) activities [25].
  • Recent studies, also in halothane-anesthetized rat, demonstrated that the region of the basal forebrain encompassing the medial septum/vertical limb of the diagonal band of Broca (MS) is a site at which noradrenergic efferents act to influence EEG state via actions at beta-receptors [26].
  • We evaluated the use of the following routinely available clinical investigations--fasting intermediary metabolites (lactate, pyruvate, ketone bodies, etc.) in blood and cerebrospinal fluid, serum creatine kinase estimation, EMG, EEG, CT, MRI and histological/histochemical muscle biopsy analysis [27].

Associations of Electroencephalography with chemical compounds

  • Acetaldehyde, the proximate metabolite of ethanol, when injected intravenously in rats produced electroencephalogram (EEG) changes similar to those observed after ethanol administration; that is, low doses activated the cortical EEG and higher doses caused activation followed by synchronization [28].
  • At low infusion dosage when the EEG was unaffected, concentrations of acetaldehyde in the blood were equal to or greater than those which occur during intoxication [28].
  • The EEG was the most useful neurodiagnostic aid followed by technetium and computed axial tomographic scans [29].
  • In urethane-anesthetized rats, neocortical EEG showed a periodical alternation between two states: a slow-wave state (SWS) characterized by large and slow waves and a fast-wave state (FWS) characterized by faster waves [30].
  • In vivo experiments using brain dialysis demonstrated that kainate reversibly abolished recurrent inhibition and induced an epileptic-like electroencephalogram (EEG) activity [31].

Gene context of Electroencephalography

  • Statistical parametric mapping of 5-HT1A receptor binding in temporal lobe epilepsy with hippocampal ictal onset on intracranial EEG [32].
  • Effects of alcohol on the EEG in Asian men with genetic variations of ALDH2 [33].
  • The peptide may become more effective on sleep EEG in older than in younger subjects, because of the decline of GHRH-GH axis activity, which may contribute to sleep disturbances in aging [34].
  • The somatostatin analogue octreotide impairs sleep and decreases EEG sigma power in young male subjects [35].
  • Because the influence of peripheral SRIF administration on sleep EEG in the elderly is unknown, we administered 50 micrograms SRIF-14 every hour between 2200 and 0100 hours to controls with an age range from 60 to 73 years (mean +/- SD 67.4 +/- 5.1 years) [34].
