... young adults were used as controls to measure EEG and autonomic activity during craft activities in three conditions: alone, parallel, and nonparallel. EEG was analyzed using exact low-resolution electromagnetic tomography, and autonomic activity was analyzed using Lorenz plot analysis. Results...

... the baseline EEG using independent component analysis (ICA). The HEP-peak was detected in a bandwidth of 20 ms around 8 ms and 270 ms (N8, N270) after the R-peak of the electrocardiogram signal. Differences between remitters and non-remitters were statistically assessed by repeated-measures ANOVAs...

...Kristin Koller-Schlaud; Andreas Ströhle; Joachim Behr; Elisabeth Bärwolf Dreysse; Johannes Rentzsch Introduction: Asymmetrical alpha and frontal theta activity have been discussed as neurobiological markers for antidepressant treatment response. While most studies focus on resting-state EEG...

... alpha EEG asymmetry in healthy subjects during a simple emotional face processing task. Twenty-three healthy adults participated in two sessions with a test-retest interval of about 1 week. Reliability was estimated with Pearson’s correlation coefficient and paired t test. Results revealed moderate...

... effective in terms of its alerting effect for the following variables: subjective sleepiness, latency of P300 response, and absolute EEG power in higher beta (24–34 Hz) and gamma (35–50 Hz) range at each of the 19 recording electrodes. However, no differences in current power density were observed...

...Bianca Lee Thomas; Margaretha Viljoen Objective: The aim of this study was to assess baseline EEG brain wave activity in children with attention-deficit/hyperactivity disorder (ADHD) and to examine the effects of evoked attention and methylphenidate on this activity. Method: Children with ADHD (n...

...-depressive illness'). According to the vigilance regulation model, the regulation of brain arousal (referred to as ‘vigilance') when assessed via EEG is an emerging biomarker linked to the pathogenesis of manic and depressive episodes. On this basis, the present study aimed to assess whether carriers of BD...

... = 30) and healthy controls (HCs; n = 30). Method: Each 1-second segment of 15-min resting EEGs from 141 healthy subjects was classified as 1 of 7 different vigilance stages using the Vigilance Algorithm Leipzig. K-means clustering was used to distinguish different patterns of EEG vigilance regulation...

...Sandra Giménez; Sergio Romero; Miguel Angel Mañanas; Manuel-José Barbanoj Background/Aims: The correlation between theta activity during wakefulness and slow-wave activity (SWA) during sleep observed after sleep deprivation suggests such patterns can be used as electroencephalogram (EEG) biomarkers...

...Marianne Littel; Ingmar H.A. Franken; Jan W. Van Strien Aims: To investigate the changes in the electroencephalographic (EEG) spectrum in smokers during exposure to a neutral and a smoking-related cue to determine whether these EEG changes are still present in ex-smokers after prolonged abstinence...

... and electroencephalographic (EEG) indices of frontal hemispheric asymmetry, which has been shown to be sensitive to mood states, the purpose of this study was to investigate the neural basis of cue-elicited cigarette craving, its variation with experimentally induced depressed mood, and with differences in gender and smoker...

...N.E. Noldy; C.V. Santos; N. Politzer; R.D.G. Blair; P.L. Carlen Quantitative EEG changes were studied during cocaine withdrawal in 36 subjects. All subjects had used cocaine orally (n = 28) or intravenously (n = 8) within 48 h of admission to an inpatient unit. EEGs were recorded 2 and 6 days...

...M. Ziller; K. Frick; W.M. Herrmann; S. Kubicki; I. Spieweg; G. Winterer Various quantitative descriptors for EEG data will be compared taking sleep as an example. In this contribution, Hjorth’s mobility and complexity measures will be used to classify sleep stages. The results will be compared...

... studied. The EEG was recorded at rest with eyes closed (EC), during blocking reaction, fixation and mental arithmetic tasks. The computerized EEG study, performed before and after therapy, utilized spectral analysis; data underwent statistical evaluation including ANOVA and correlation analysis. Before...

...H. Depoortere; M. Decobert; P. Granger; D. Françon The sedative potential of mizolastine, a new, potent and selective antagonist of histamine H 1 -receptors, has been evaluated in the rodent with EEG techniques. In chronically implanted rabbits, sedation was observed in ECoG recordings after...

... prepared in two different formulations. Sedation was measured as sleep propensity and power increase in the low frequency delta band of the quantified EEG, based on 5-min polygraphic (EEG, EOG, EMG) recordings under resting conditions, which were performed immediately before, and 30, 60, 90, and 120 min...

...Michal Hrdlička; Miroslav Moráň; Jaromír Vachutka; Marek Blatný; Jirina Rozinková EEG records of electroconvulsions were evaluated according to a five-point semiquantitative scale grading the intensity of the paroxysmal activity. A more favorable therapeutic effect of ECT was found to be associated...

... to cyclandelate; 69 to placebo). Quantitative-topological EEG, event-related potentials (P300) and psychophysiological interview-based rating scales were used. The efficacy of cyclandelate was demonstrated in the confirmatory statistical sense using a global Hailperin-Rüger test on 10 predefined primary variables...

... was an inverted-U function, but this effect was possibly confounded by baseline differences. The following effects on EEG spectral-band magnitude were also obtained: (1) nicotine yields > 0.17 mg decreased delta; (2) nicotine yields of 0.37 and 0.48 mg decreased theta in a.m. subjects; (3) nicotine yields...

...Vladimir A. Feshchenko; Robert A. Veselis; Ruth A. Reinsel The EEG effects of 3 intravenous sedative drugs from different chemical families were studied during conscious sedation in 47 normal volunteers. The drugs studied were midazolam (a benzodiazepine), propofol (an alkylphenol) and thiopental...
