Who has had an EEG? Can i get some info?

Answer 1

I had an EEG (Normal) 2 weeks ago and will be having another one on Tuesday (sleep Deprived). From a patients perspective - they are non evasive and not painful. The person who did it - spent about 20 minutes marking little crosses on my head. I think there were about 20-25 all up (I gave up counting). Then I was asked to lay on a bed whilst she attached special wires to my head. To do this she used a special kind of glue. Once I was all wired up I had to lay very still and follow some instructions. From memory I had to just lay there with my eyes closed for a few minutes, then breathe deeply for a few minutes, then look at a flashing light for a few more minutes. I think all up the testing took about 20minutes. It was totally painless and not frightening at all. In fact it was easy to forget you were wired up. After the test was done - the nurse removed the wires with a special solvent to get rid of the glue. No pain there either. As far as medical tests go - it was fine and free from dramas. Although having to go without sleep on Monday night for Tuesday's test is going to be challenging...... :-) Hope if you have to have an EEG all goes well.

Answer 2

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.
