The principle, classification and clinical application of brain electrical topographic map

Brain electrical apparatus, which is a kind of medical electronic instruments, is a kind of medical electronic instruments. It is a kind of brain disease which can help doctors to check the pathological changes of the brain caused by the brain diseases.
Brain electrical topographic map instrument generally by the input part, the amplifying part, the adjustment part, the recording or the display part as well as the power source part. Generally can be divided into video EEG, digital EEG, dynamic EEG, etc.. Video EEG instrument 24 hours real-time monitoring of brain waves, can help doctors more direct observation of patients, a comprehensive understanding of patient information, accurate identification of false. Digital EEG instrument is set of EEG detection amplification, computer analysis, printing and other functions in one. Ambulatory EEG is a micro recording device, which can record the brain electrical activity of the patients in the normal environment.
EEG is a non-invasive diagnostic instrument, which has a certain reference value for the diagnosis of brain diseases, especially for the diagnosis of intracranial lesions and cranial trauma and the quantitative analysis of brain function.
EEG is currently the main help in the diagnosis of the following diseases, including the consciousness of the disease, intracranial space occupying lesions, epilepsy, cerebral vascular disease, brain injury, intracranial inflammation and encephalopathy. Range of diagnosis and treatment for the diagnosis of intracranial vascular occlusive disease; diagnosis of extracranial vascular occlusion lesions associated with carotid artery compression test, to understand the collateral circulation is good; influence on cerebral blood flow velocity in evaluation of extracranial vascular; diagnosis to track detection for dissecting aneurysm of internal carotid artery; venous malformations of the arteries that supply blood to the detection and identification of dynamic; other intracranial vascular disease diagnosis; intermittent monitoring to track research
