OBJECTIVES The main objective was to indicate sufficient general anaesthesia (GA) inhibition for negative experience rejection in GA. PATIENTS AND METHODS We investigated the group of patients (n = 17, mean age 63.59 years, 9 male--65.78 years, 8 female - 61.13 years) during GA in open thorax surgery and analyzed EEG signal by power spectrum (pEEG) delta (DR), and gamma rhythms (GR). EEG was ...
The present research aims at examining the power spectrum and exploring functional brain connectivity/disconnectivity during concentration performance, as measured by d2 test of attention creativity CREA in typically developing children. To this end, we examined connectivity using phase synchrony (i.e., locking index (PLI) over EEG signals acquired Emotiv EPOC neuroheadset 15 children aged 9- t...
Objective: To analyze the psychophysiological response during takeoff, landing, air-air attack and air-ground maneuvers. Methods: A total of 11 expert pilots (age=33.36 (5.37)) from Spanish Air Force participated in this cross-sectional study. Participants had to complete a flight simulator following missions: 1) takeoff; 2) Air-air attack; 3) Air-Ground attack, 4) Landing. The electroencephalo...
The data represented here are in relation with the manuscript "Quantitative assessments of extracellular EEG to classify specific features of main phases of seizure acquisition based on kindling model in Rat" (Jalilifar et al., 2017) [1] which quantitatively classified different main stages of the kindling process based on their electrophysiological characteristics using EEG signal processing. ...
PRIMARY OBJECTIVE This prospective controlled non-randomized study investigated the effects of robotic gait training on electroencephalographic (EEG) brain activity in patients with impaired consciousness due to severe traumatic brain injury (TBI). METHODS Twelve TBI patients and 14 healthy controls underwent a single training session on a computer-driven gait orthosis (Lokomat®). The sensory...
The human electroencephalogram (EEG) is globally characterized by a 1=f power spectrum superimposed with certain peaks, whereby the ‘‘alpha peak’’ in a frequency range of 8–14Hz is the most prominent one for relaxed states of wakefulness. We present simulations of a minimal dynamical network model of leaky integrator neurons attached to the nodes of an evolving directed and weighted random grap...
Electroencephalography (EEG) recordings during sleep are often contaminated by muscle and ocular artefacts, which can affect the results of spectral power analyses significantly. However, the extent to which these artefacts affect EEG spectral power across different sleep states has not been quantified explicitly. Consequently, the effectiveness of automated artefact-rejection algorithms in min...
The sleep EEGs of 9 young adult males (age 20-28 years) and 8 middle-aged males (42-56 years) were analyzed by visual scoring and spectral analysis. In the middle-aged subjects power density in the delta, theta and sigma frequencies were attenuated as compared to the young subjects. In both age groups power density in the delta and theta frequencies declined from NREM period 1 to 3. In the sigm...
Blinding of modality has been influenced decision multimodal in several circumstances. Sometimes, certain electroencephalogram (EEG) signal is omitted to achieve the highest accuracy performance. Therefore, aim for this paper enhance parameters EEG signals based on music applications. The structure evaluated with performance measure ensure implementation parameter value valid apply equation. mo...
