Electroencephalography is a domain concerning recording and interpretation of the electroencephalogram. Electroencephalogram (EEG) is a record of the electric signal generated by the cooperative action of brain cells, or more precisely, the time course of extracellular field potentials generated by their synchronous action. Electroencephalogram derives from the Greek words enkephalo (brain) and...

epilepsy is an important disease with a cumulative incidence of 3% all over the life and more than half of them are started from childhood. in this study we surveyed magnetic resonance imaging (mri) findings in epileptic children and its relation with clinical and demographic findings in order to find better diagnostic and treatment modalities for these children in the future. in this cross sec...

background: we evaluated the diagnostic value of electroencephalography (eeg), video-eeg monitoring (vem) and magnetic resonance imaging (mri) of the brain with epilepsy protocol in patients with complex partial epilepsy. methods: forty-two consecutive patients underwent complete neurological examination, eeg, and mri with a modified epilepsy protocol. a subset of these patients (n = 29) also u...

PURPOSE To describe the development and implementation of video EEG telemetry (VT) in the patient's home (home video telemetry, HVT) in a single centre. METHODS HVT met the UK Medical Research Council definition of a complex intervention, and we used its guidance to evaluate the process of piloting, evaluating, developing and implementing this new clinical service. The first phase was a feasi...

In this paper, unique approach is presented for the electroencephalography (EEG) signals analysis. This is based on Eigen values distribution of a matrix which is called as scaled Hankel matrix. This gives us a way to find out the number of Eigen values essential for noise reduction and extraction of signal in singular spectrum analysis. This paper gives us an approach to classify the EEG signa...

The commonest and simplest operational definition of consciousness is, the state of the patient’s awareness of self and environment and his responsiveness to external stimulation and inner need. Therefore, unconsciousness has the opposite meaning, that is, a state of unawareness of self and environment or a suspension of those mental activities by which people are made aware of themselves and t...

In recent years, neural networks showed unprecedented growth that ultimately influenced dozens of different industries, including signal processing for the electroencephalography (EEG) process. Electroencephalography, although it appeared in first half 20th century, was not changed physical principles work to this day. But technology made significant progress area through use networks. many mod...
