When a routine EEG is normal and there is a high suspicion or need to confirm epilepsy, it may be repeated or performed with a longer duration in the epilepsy monitoring unit (EMU) or at home with an ambulatory EEG.
EEG electrode positions in the 10-10 system using modified combinatorial nomenclature, along with the fiducials and associated lobes of the brain. When recording a more detailed EEG with more electrodes, extra electrodes are added using the 10% division , which fills in intermediate sites halfway between those of the existing 10–20 system.
Once a lesion has been identified, ECoG may be performed to determine the location and extent of the lesion and surrounding irritative region. The scalp EEG, while a valuable diagnostic tool, lacks the precision necessary to localize the epileptogenic region.
Current research being performed using long-term video-EEG monitoring mostly focuses on the mouse model known as C57BL/6J which can be used to induce behavioral convulsive (CS) and electrographic-nonconvulsive (NCS) seizures. These seizures can then be monitored over a 4-18 week period, which is a much longer period than most humans are ...
Stereoelectroencephalography (SEEG) is the practice of recording electroencephalographic signals via depth electrodes (electrodes surgically implanted into the brain tissue).
Electroencephalography is the measurement of brain activity through the surface of the scalp. [1] 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]
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 ...
An electroencephalogram (EEG) is an electrical recording of the activity of the brain taken from the scalp. An EEG can be used to diagnose seizures , sleep disorders , and for monitoring of level of anesthesia during surgery.
