Fifteen male users of oral snuff participated in an experiment where we used an auditory-visual vigilance task to study nicotine effects on P300 and response parameters. Quantitative EEG was also studied. Fifteen male nonusers served as controls. We found some decrease of response times and a tendency towards improved signal detection. P300 parameters were not affected in this study. Quantitati...
M ajor depressive disorders (MDD) are associated with a variety of sleep macroarchitectural disturbances, based on visual stage scoring of the sleep electroencephalogram (EEG). These include insomnia, impaired sleep continuity, abnormalities in the amount and timing of rapid eye movement (REM) sleep, reductions in deep non-REM (NREM) sleep, increased awakenings during the night and increased li...
The quantitative analysis of electroencephalographic activity (EEG) is a useful tool for the study of changes in brain electrical activity during cognitive and behavioral functions in several experimental conditions. Their recording and analysis are currently carried out primarily through the use of computer programs. This paper presents a computerized program (EEGbands) created for Windows ope...
We read with interest the findings of the retrospective investigation of the role of electroencephalography (EEG) in the treatment of hospitalized patients by Harmon and colleagues in the December 2013 issue of The Journal of the American Osteopathic Association.1 In their cohort of 200 inpatients, EEG was found to rarely contribute to clinical decision making and in no case resulted in a chang...
INTRODUCTION The aim of this study was to build a random forest classifier to improve the diagnostic accuracy in differentiating dementia with Lewy bodies (DLB) from Alzheimer's disease (AD) and to quantify the relevance of multimodal diagnostic measures, with a focus on electroencephalography (EEG). METHODS A total of 66 DLB, 66 AD patients, and 66 controls were selected from the Amsterdam D...
Background : For newborn infants in critical care, continuous monitoring of brain function can help identify infants at-risk of brain injury. Quantitative features allow a consistent and reproducible approach to EEG analysis, but only when all implementation aspects are clearly defined. Methods: We detail quantitative features frequently used in neonatal EEG analysis and present a Matlab softwa...
PURPOSE To describe the development and implementation of video EEG telemetry (VT) in the patient's home (home video telemetry, HVT) in a single centre. METHODS HVT met the UK Medical Research Council definition of a complex intervention, and we used its guidance to evaluate the process of piloting, evaluating, developing and implementing this new clinical service. The first phase was a feasi...
In this paper a new approach to the electroencephalogram (EEG) signal simulation based on the artificial neural networks (ANN) is proposed. The aim was to simulate the spontaneous human EEG background activity based solely on the experimentally acquired EEG data. Therefore, an EEG measurement campaign was conducted on a healthy awake adult in order to obtain an adequate ANN training data set. A...
Despite the widespread use of caffeine as a central nervous stimulant, the central pharmacodynamic properties of the drug have not yet been conclusively evaluated in humans. The present study was undertaken to assess the acute effects of caffeine on measures of topographical quantitative electroencephalogram (EEG) in normal subjects. Ten healthy male volunteers (mean age +/- SD 25 +/- 4 years) ...
OBJECTIVES Diagnosis of the psychiatric diseases is a bit challenging at the first interview due to this fact that qualitative criteria are not as accurate as quantitative ones. Here, the objective is to classify schizophrenic patients from the healthy subject using a quantitative index elicited from their electroencephalogram (EEG) signals. METHODS Ten right handed male patients with schizop...
