General introduction

The bioelectricity current effected by brain wave---electroencephalograph which has regularity contains mass information of brain activity. The method using EEG to describe, record and measure the brain function has been used for nearly eighty years and has been proved to be scientific and practical. It also has been used widely for scientific research of advanced brain activity and neurology diagnosis to brain disease such as epilepsy, encephaloma encephalitis, cerebral injury and cerebrovascular disease.

Equipped with original parts from America, the system adopts advanced domestic and overseas technology combining with over thirty years’

Designing and producing experience, ensuring the instrument to detect pinpoint EEG signals under normal environment with authenticity and purity. During the computer analysis and processing period, the adoption of high-precision A/D sampling, high-speed processing software, high-resolution large screen dynamic color display, high-density real time heat-ray description, and advanced color inkjet graph printing ensure the authenticity, accuracy and credibility of the examining result.
