To investigate inter- and intra-hemispheric electroencephalography (EEG) coherence at rest and during photic stimulation of patients with Alzheimer's disease (AD). Thirty-five patients (12 males, 23 females; 52 to approximately 64 y) and 33 sex- and age-matched controls (12 males, 21 females; 56 to approximately 65 y) were recruited in the present study. EEG signals from C3-C4, P3-P4, T5-T6 and...
physical balance is one of the important factors in daily sport activities.dynamic balance helps maintain the balance of those forces imposed on body insports and an increase in this balance improves motor and sport performance. theaim of this study was to determine the effects of neurofeedback training on dynamicbalance of young men. 24 male undergraduate students voluntarily participated inth...
Abstract Background Headache is one of the most common neurological symptoms reported in adolescence. The value electroencephalography (EEG) diagnostics patients with headache controversial; however, quantitative EEG (QEEG) can clarify pathophysiology headache. Aim study was to assess QEEG and daily habits adolescents or without a clinical history (according answers screening questionnaire), id...
To investigate the features of electroencephalography (EEG) power and coherence at rest and during a working memory task of patients with mild cognitive impairment (MCI). Thirty-five patients (17 males, 18 females; 52~71 years old) and 34 sexand age-matched controls (17 males, 17 females; 51~63 years old) were recruited in the present study. Mini-Mental State Examination (MMSE) of 35 patients w...
BACKGROUND In this study we analyse the behaviour, potential clinical application and optimal cortical sampling location of the spectral parameters: (i) relative alpha and beta power; (ii) spectral edge frequency 90%; and (iii) spectral entropy as monitors of moderate propofol-induced sedation. METHODS Multi-channel EEG recorded from 12 ASA 1 (American Society of Anesthesiologists physical st...
Introduction Over the last decades, considerable levels of electromagnetic fields (EMFs) have been characterized in the living environment. Recent epidemiological studies on occupational and residential exposure to EMF have shown that 50/60 Hz fields, known as extremely low frequencies (ELF), have various biological effects, such as angiogenesis. This study aimed to investigate the effect of en...
novel structure of low phase noise and high output power monolithic microwave integrated circuit (MMIC) oscillator is presented in order to use it 5G applications. The based on the ED02AH process which allows us design a keeping minimum size impossible have using other technologies since oscillators are sensitive components above 20 GHz. studied, designed, optimized GaAs substrate from OMMIC fo...
The millions of deaths from cholera during the past 200 y, coupled with the morbidity and mortality of cholera in Haiti since October 2010, are grim reminders that Vibrio cholerae, the etiologic agent of cholera, remains a scourge. We report the isolation of both V. cholerae O1 and non-O1/O139 early in the Haiti cholera epidemic from samples collected from victims in 18 towns across eight Arron...
In this study event related coherence of patients with Alzheimer type of dementia (AD) was analyzed by using a visual oddball paradigm as stimuli. A total of 21 mild probable AD subjects (10 untreated, 11 treated) were compared with a group of 19 healthy controls. The members of the groups had their EEG recorded from 12 electrodes by means of a visual oddball paradigm. The evoked coherence was ...
