Description

Technical Field

[0001] The invention relates to the technical field of measuring and positioning devices, in particular to an electroencephalograph measuring and positioning device. Background Art

[0002] The electroencephalogram (EEG) is a graph obtained by amplifying and recording the spontaneous biopotential of the brain from the scalp through precise electronic instruments. It is the spontaneous and rhythmic electrical activity of brain cell groups recorded by electrodes. Conventional EEG, dynamic EEG monitoring, video EEG monitoring, and EEG-tracing brain activity graphs can not only illustrate the limited or diffuse pathological manifestations caused by brain diseases such as epilepsy, tumors, trauma, and degenerative diseases, but also have diagnostic value for changes in the central nervous system caused by extra-brain diseases such as metabolic and endocrine disorders and poisoning. EEG examination is an effective method for examining changes in brain function. Since changes in brain function are dynamic and changeable, for some patients with clinical brain dysfunction, if no abnormalities are found in an EEG examination, the presence of brain disease cannot be completely ruled out, and EEG reexaminations should be performed regularly to accurately detect diseases.
