Cumulative evidence of potential benefits of electroencephalography (EEG) and evoked potentials in the management of patients with acute cerebral damage has been confirmed. Continuous EEG monitoring is the best method for detecting nonconvulsive seizures and is strongly recommended for the treatment of status epilepticus. Continuously displayed, validated quantitative EEG may facilitate early d...
ثبت فعالیت الکتریکی مغز (eeg) دارای استفاده های تشخیصی عمده در کاربرد های بالینی و تحقیقات پزشکی است. این ثبت توأم با آرتیفکت هایی از جمله آرتیفکت های ناشی از فعالیت الکتریکی عضلات، سیگنال (emg) و فعالیت الکتریکی چشم سیگنال (eog) است. آرتیفکت eog که به نام آرتیفکت چشمی شناخته می شود، در سیگنال eeg ثبت شده توسط الکترودهایی که به قسمت پیشانی نزدیک ترند دامنه بیشتری دارد. آرتیفکت چشمی ناشی از فعال...
Introduction: Methamphetamine consumption is associated with cognitive and neuropsychological damage. Determining the effect of this substance on the activities and characteristics of the human brain can lead to the prevention and treatment of complications caused by abuse. There are diverse chemical formulas in Iran with unknown properties. Moreover, few studies have focused on electrophysiolo...
PURPOSE The aim of this study was to evaluate the mechanism of parametric excitation of the electroencephalographic (EEG) rhythms by modulated microwave radiation. MATERIALS AND METHODS The model of parametric excitation based on polarization of water molecules was proposed and experimental results compared to the model. The experiments were carried out on 28 human volunteers. The 450 MHz mic...
The following pages represent a summary of many articles, papers, reviews and books on medications and the CNS function, and finally nearly 30 years of experience in clinical and research EEG. The difficulty in this area is the definitions of bands varies, the methods of analysis range from visual inspection of the raw EEG to quantitative measures, not all of which are clearly defined... and th...
Arousal is largely controlled by the ascending arousal system of the hypothalamus and brainstem, which projects to the corticothalamic system responsible for electroencephalographic (EEG) signatures of sleep. Quantitative physiologically based modelling of brainstem dynamics theory is described here, using realistic parameters, and links to EEG are outlined. Verification against a wide range of...
