EEG can detect the onset and spatio-temporal (location and time) evolution of seizures and the presence of status epilepticus. It is also used to help diagnose sleep disorders, depth of anesthesia, coma, encephalopathies, cerebral hypoxia after cardiac arrest, and brain death.
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.
If EEGs are recorded after intentionally stimulating the brain, then the resulting data is called an event related potential. The firing of neurons throughout the brain has been known to have localized relationships to certain functions, processes and reactions to stimuli. With proper equipment it is possible to locate where in the brain ...
If, after eating raw fish, you experience signs of food poisoning such as nausea, vomiting, diarrhea or stomach cramps, contact your health care provider immediately.
Recording of the Electrogastrogram can be made from either the gastrointestinal surface mucosa, serosa, or the external skin surface.The cutaneous electrogastrography provides an indirect representation of the electrical activity, that has been demonstrated in numerous studies to exactly correspond to simultaneous recordings of the mucosa or serosa.
Using their broader training, physicians in electrodiagnostic medicine, often perform more detailed evaluations which may include laboratory tests, CT or MRI scans, genetic evaluation, biopsy of nerve, skin, or muscle, or perform neuromuscular ultrasound. A more complete listing of disorders and testing can be found under neuromuscular medicine.
The biomarker test is a spinal tap test (also called a lumbar puncture) that uses a needle to remove cerebrospinal fluid (i.e. the fluid inside your spine) to look for these specific clumping ...
The C1 and P1 (also called the P100) are two human scalp-recorded event-related brain potential (event-related potential (ERP)) components, collected by means of a technique called electroencephalography (EEG). The C1 is named so because it was the first component in a series of components found to respond to visual stimuli when it was first ...
