Electroencephalography (EEG) is an established measure in the field of brain resting state with a range of quantitative methods (qEEG) that yield unique information about neuronal activation and synchronization. Meanwhile, in the last decade, functional magnetic resonance imaging (fMRI) studies have revealed the existence of more than a dozen resting state networks (RSNs), and combined qEEG and...

Autism-Spectrum Disorders (ASD) are thought to be associated with abnormalities in neural connectivity at both the global and local levels. Quantitative electroencephalography (QEEG) is a non-invasive technique that allows a highly precise measurement of brain function and connectivity. This review encompasses the key findings of QEEG application in subjects with ASD, in order to assess the rel...

Background: We aim to assess the role of quantitative electroencephalography (QEEG) derived indices predict post-stroke disability. Methods: included observational studies (sample-size≥10) patients with stroke who underwent EEG and a follow-up outcome assessment was available either in form modified Rankin scale (mRS) or National Institute (NIHSS) Fugl-Meyer (FMA). QEEG analyzed were delta-alph...

In the last decade, many studies have tried to define the neural correlates of attention deficit hyperactivity disorder (ADHD). The main aim of this study is the comparison of the ERPs independent components in the four QEEG subtypes in a group of ADHD adults as a basis for defining the corresponding endophenotypes among ADHD population. Sixty-seven adults diagnosed as ADHD according to the DSM...

Background: Transcranial Photobiomodulation (t-PBM) is a current, innovative method that used in the therapy of many neurological and psychological diseases. Its mechanisms action have been investigated most well described ways are its effects on mitochondrial function heat/light-activated ion channels neurons membrane. It has suggested increase cerebral blood flow alterations membrane dominant...

Background. Quantitative electroencephalography (QEEG) databases have been developed for the eyes closed (EC) condition. The development of a cognitive activation database is a logical and necessary development for the field. Method. Brain activation was examined by QEEG during several tasks including EC rest, visual attention (VA). auditory attention (AA), listening to paragraphs presented aud...

Posterior circulation cerebral infarction (PCCI) can lead to deceased infratentorial blood flow (CBF) and metabolism. Neural activity is closely related regional both spatially temporally. Transcranial Doppler (TCD) combined with quantitative electroencephalography (QEEG) a technique that evaluates neurovascular coupling involves synergy between the metabolic vascular systems. This study aimed ...

OBJECTIVE It has been proposed that 50%-75% of the efficacy of antidepressant medication represents the placebo effect, since many depressed patients improve when treated with either medication or placebo. This study examined brain function in depressed subjects receiving either active medication or placebo and sought to determine whether quantitative electroencephalography (QEEG) could detect ...
