?? What is EEG

Electroencephalography (EEG) is the recording of electrical activity
along the scalp produced by the firing of neurons within the brain

In clinical contexts, EEG refers to the recording
of the brain's spontaneous electrical activity over a short period of time,
usually 20–40 minutes, as recorded from multiple electrodes placed on the scalp


In neurology, the main diagnostic application of EEG is in the case of epilepsy
as epileptic activity can create clear abnormalities on a standard EEG study

A secondary clinical use of EEG is in the diagnosis of coma
encephalopathies, and brain death

EEG used to be a first-line method for the diagnosis of tumors
stroke and other focal brain disorders, but this use has decreased with the advent
of anatomical imaging techniques such as MRI and CT
