Electroencephalography (EEG) and syncope; a retrospective study

Application of Electroencephalography (EEG) in Ergonomics: A systematic review study

Background and Objectives: Electroencephalography is one of the non-invasive and relatively inexpensive methods that can be used to evaluate neurophysiology and cognitive functions. This systematic review study was performed with the aim of using electroencephalography (EEG) in ergonomics. Methods: In this review study, all articles published in Persian and English on the application of elec...

Electroencephalography (eeg)

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...

Electroencephalography ( EEG ) and Unconsciousness

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...

Syncope during EEG recording.

A 75-year-old man had several syncopes with severe skull contusions (figure 1). These events were not preceded by vegetative symptoms such as nausea, dizziness, or palpitations. Holter-EKG was normal and an EEG was performed for suspected epilepsy, during which complete atrioventricular block without ventricular escape-rhythm occurred (figure 2A). Six seconds later, the EEG showed progressive s...
