How does electroencephalogram see a result

summary

Sometimes got mental illness, generally need to do multiple EEG, to check, many people may not know how to see EEG in the end? It seems that I can't see any way. Now let's popularize the science of EEG.

How does electroencephalogram see a result

First, electroencephalogram (EEG) is a graph obtained by amplifying and recording the spontaneous biological potential of the brain from the scalp with precise electronic instruments. It is the spontaneous and rhythmic electrical activity of brain cell groups recorded by electrodes. Routine EEG, dynamic EEG and video EEG were monitored.

Second: electroencephalogram examination is an effective method to check the changes of brain function. Because the changes of brain function are dynamic and changeable, we can't completely rule out the existence of brain diseases when we do an electroencephalogram examination for some patients with clinical brain dysfunction and find no abnormality. We should regularly review the electroencephalogram to find out the disease accurately I'm sick.

Third: brain tissue itself can spontaneously generate bioelectrical activities. Electroencephalogram (EEG) is the result of the electric activity of brain cells and electrodes on the scalp, which is amplified and recorded on paper to form a certain graphic curve. It reflects the functional state of the brain at any time. Under normal circumstances, these bioelectrical activities are very small (one millionth of a volt) and cannot be recorded by ordinary instruments. The waveform recorded by the electroencephalograph is amplified by one million times.

matters needing attention

Electroencephalogram is to record the changes of our condition, so understanding how to see the results of electroencephalogram will be more convenient in our daily life. For example, epilepsy, a kind of disease, long-term illness, you can see EEG also can have some understanding.
