The EEG machine has wires that must be attached to scalp to detect the activities of different parts of the brain .for example scientist used that to record the brain activity of people who were going through REM sleep.after the brain activities are sent to the EEG machine ,it draw a diagram which shows the activity of the brain. .

Electroencephalography
From Wikipedia, the free encyclopedia
Jump to: navigation, search
For the comic character, see Brainwave (comics)
Electroencephalography is the neurophysiologic measurement of the electrical activity of the brain by recording from electrodes placed on the scalp or, in special cases, subdurally or in the cerebral cortex. The resulting traces are known as an electroencephalogram (EEG) and represent an electrical signal (postsynaptic potentials) from a large number of neurons. These are sometimes called brainwaves, though this use is discouraged [1]. The EEG is a brain function test, but in clinical use it is a "gross correlate of brain activity" [2]. Electrical currents are not measured, but rather voltage differences between different parts of the brain.
EEGs are frequently used in experimentation because the process is non-invasive to the research subject. The subject does not need to make a decision or behavioral action in order to log data, and it can detect covert responses to stimuli, such as reading. The EEG is capable of detecting changes in electrical activity in the brain on a millisecond-level. It is one of the few techniques available that has such high temporal resolution. The other common technique is MEG.
Clinical use
EEG in various forms is most useful as a tool for monitoring and diagnosis in certain clinical situations:
epilepsy and syncope (fainting)
sleep disorders
coma and brain death
It is sometimes useful in assessing dementia, when other examinations are equivocal. In some jurisdictions it has a legal significance and formal criteria are used to assess brain death. Current research is being done to determine if EEG may also be used to help monitor clinical depression treatment, but such studies are still in the clinical stages.

EEG means electroencephalograph.
It is used to record brain activity.
EEG is only a recording and does not do anything to the brain.

EEG is an Electroencephalogram , its a brain scan, it does NOT activate the brain, they are most likely looking to see if he is braindead, or has any brain activity going on.

it means an electroencephalograph...........its a machine that is used to record brain activity. i think you may have misunderstood the doctors when they said they did an EEG to activate the brain

The chicken came before the EEG, but the egg probably came before the chicken.

It stands for Electroencephalography which is used to diagnose conditions, such as epilepsy due to abnormal electrical activity within the brain.
