summary

Most of us can't understand EEG. We often take our own EEG, but we don't know what's going on. Let me tell you how to understand EEG.

How to understand EEG

First of all, electroencephalogram (EEG) is drawn from the scalp through the electrical activity of the existing electrodes and brain cells. After amplification, it is recorded on paper to form a certain graphic curve. It reflects the functional state of the brain at any time.

Secondly, under normal circumstances, these bioelectrical activities are very small (one millionth of a volt), which can not be recorded by ordinary instruments. The waveform recorded by the electroencephalograph is amplified by one million times.

Finally, when the brain lesions, EEG will have the corresponding abnormal changes. Especially in the case of epilepsy, EEG will appear epileptic discharge, this kind of discharge not only in the seizure, but also in the intermission period, which is of great significance for the diagnosis, positioning, qualitative and curative effect observation of epilepsy.

matters needing attention

Electroencephalogram is very important. It's better for everyone to understand it. Electroencephalogram can reflect good problems. Only when they can understand it, can they timely understand their physical health and find problems and treat them early.
