Electroencephalography data can be viewed as a qualitative wave form, or it can be further processed through analytical procedures to produce quantitative electroencephalography (qEEG). [2] If qEEG data is mapped from multiple parts of the brain then it is a topographic qEEG (also known as brain electrical activity mapping or BEAM).
Electrode locations of International 10-20 system for encephalography recording. The 10–20 system or International 10–20 system is an internationally recognized method to describe and apply the location of scalp electrodes in the context of an EEG exam, polysomnograph sleep study, or voluntary lab research.
EEG analysis is exploiting mathematical signal analysis methods and computer technology to extract information from electroencephalography (EEG) signals. The targets of EEG analysis are to help researchers gain a better understanding of the brain; assist physicians in diagnosis and treatment choices; and to boost brain-computer interface (BCI) technology.
Electroencephalography (EEG) [1] is a method to record an electrogram of the spontaneous electrical activity of the brain. The biosignals detected by EEG have been shown to represent the postsynaptic potentials of pyramidal neurons in the neocortex and allocortex . [ 2 ]
Electromagnetic Source Imaging is a functional imaging technique, which uses Electroencephalography (EEG) and/or Magnetoencephalography measurements to map functional areas of the Cerebral cortex. [ 1 ]
Stereoelectroencephalography (SEEG) is the practice of recording electroencephalographic signals via depth electrodes (electrodes surgically implanted into the brain tissue).
The American Board of Clinical Neurophysiology certifies in electroencephalography (EEG), Evoked Potentials (EP), Polysomnography (PSG), Epilepsy Monitoring, and Neurologic Intraoperative Monitoring (NIOM). [12] In the US physicians typically specialize in EEG or EDX medicine but not both. [citation needed]
SSVEPs are typically measured using electroencephalography. SSVEPs are useful in research because of the excellent signal-to-noise ratio [ 2 ] and relative immunity to artifacts. [ 3 ] SSVEPs also provide a means to characterize preferred frequencies of neocortical dynamic processes.
