EEG (electroencephalogram) - Mayo Clinic An electroencephalogram (EEG) is a test that measures electrical activity in the brain This test also is called an EEG The test uses small, metal discs called electrodes that attach to the scalp Brain cells communicate via electrical impulses, and this activity shows up as wavy lines on an EEG recording
EEG (Electroencephalogram): What It Is, Procedure Results An EEG (electroencephalogram) is a safe, painless test that measures brain activity Your healthcare provider may order an EEG to find out why you have certain symptoms like seizures, confusion or memory loss They may use the term EEG to describe both the test (electroencephalography) and test results (electroencephalogram)
Electroencephalography - Wikipedia Electroencephalography (EEG) [1] is a method to record an electrogram of the spontaneous electrical activity of the brain The bio signals detected by EEG have been shown to represent the postsynaptic potentials of pyramidal neurons in the neocortex and allocortex [2]
Electroencephalogram (EEG) - Johns Hopkins Medicine An EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain During an EEG, electrodes are pasted onto your scalp These are small metal disks with thin wires They detect tiny electrical charges that result from the activity of your brain cells
EEG (Electroencephalogram): Uses, Procedure, Risks An electroencephalogram (EEG) detects abnormal brain waves that cause seizures EEG uses include diagnosing epilepsy, sleep disorders, and brain tumors
