Analyzing and Processing EEG-based Multichannel Signals Acquired during Sleeping

Processing of signals acquired from sensor systems needs accurate algorithms to extract information of interest concerning the problem under study. In this work Empirical Mode Decomposition method is used on EEG signals obtained during polysomnography examination, when electromyographic (EMG) signals are acquired too. EMD method decomposes a signal into components named Intrinsic Mode Functions (IMF) which can exhibit important time-frequency information related to signals under observation

EEG correlates of cognitive load in a multiple choice reaction task

tasks were relatively easy due to small amount of S-R mappings which should be maintained in WM during task performance. In contrast, little is known about inhibition processes in choice reaction tasks with multiple S-R mappings, which maintenance would widely exceed the WM capacity (i.e. three chunks of associative information, see Cowan et al., 2012). The electroencephalogram (EEG) is a widely acknowledged and valid method for assessing cognitive load. The majority of EEG studies have reported

A face-machine interface utilizing EEG artifacts from a neuroheadset for simulated wheelchair control

Introduction Brain-computer interfaces (BCIs) have been markedly developed to serve paralysis patients via assistive technology (Brunner et al., 2014). BCIs can be categorized as invasive or noninvasive. Most BCIs are noninvasive systems. Electroencephalography (EEG) measures the field potentials produced by neurons from the scalp, and it has been widely used in clinical applications and BCI systems (Abdulkader et al., 2015; Nicolas-Alonso and GomezGil, 2012). Currently, brain acquisition

Methods for investigating complex interplay between brain regions using EEG have been carefully developed and have already begun to gain significant recognition in the field (Gómez et al., 2009; Leung et al., 2014; Li et al., 2017; Koelewijn et al., 2017). This progress may be related to several advantages of the technique. Firstly, EEG offers a noninvasive and easy-to-use method for measuring connectivity. For this reason

The diagnostic dilemma of non-convulsive status epilepticus in sporadic Creutzfeldt-Jakob disease

The differentiation between the clinical and electroencephalographic changes in nonconvulsive status epilepticus (NCSE) and those in sporadic Creutzfeldt-Jakob disease (sCJD) is a crucial question. Case report. A 77-year old woman was admitted because of fluctuating behavioural chancaseges, adynamia and apraxia since several months for diagnostic. The diagnosis of sCJD was suggested. Subsequently, she had a generalized tonic clonic seizure (GTCS) and the EEG revealed periodic

Handedness of the person can be determined from the EEG data captured and further confirmed using a simple game as testing module. EEG signals were obtained from three locations namely A1, O1 and O2. The signals were then classified into four different frequency bands: Alpha, Beta, Delta and Theta before they were used to determine the Mean EEG Coherence. Generally the

The relationship between alpha burst activity and the default mode network

Alpha rhythm, described by Hans Berger, is mainly recorded from the occipital cortex (OCC) of relaxed subjects with their eyes closed. Early studies indicated the thalamo-cortical circuit as the origin of alpha rhythm. Recent works suggest an additional relationship between alpha rhythm and the Default Mode Network (DMN). We simultaneously recorded electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) signals in 36 young males asked to alternately close and open their

EEG source activity during processing of neutral stimuli in subjects with anxiety disorders

Anxiety disorders are a social problem due to their prevalence and consequences. It is crucial to explore the influence of anxiety on cognitive processes. In this study we recorded EEG activity from 73 subjects (35 patients, 38 controls, matched for age and education)during performance of the Continuous Attention Task. We used low resolution electromagnetic tomography (LORETA) for evaluation of mechanisms of impaired cognitive performance in anxiety disorders. Analysis showed that

Most PNES are thought to be non-volitional responses to internal or external triggers perceived as threatening or challenging (Asadi-Pooya and Sperling, 2015; Brown and Reuber, 2016). The incidence of PNES has been found to be 1.4–4.9/100,000/year
