What Does An Electroencephalography Actually Do?

As mentioned before, it has the capability of measuring electrical impulses within the brain that are going between your neurons. Fluctuations in the voltage can give doctors a Birdseye view of what is going on inside. This type of test is often done to diagnose sleeping disorders, why someone has gone into a coma, and also for helping people that suffer from epilepsy and seizures. In each of those cases, brain activity has been changed to such a dramatic degree that these conditions can occur. That's why using an EEG is so important in the medical industry today.
