EEG/ERP is used in clinics or research labs by emitting 2 different stimulation signals (one Target signal and a non-Target signal) to the person wearing the equipment. The doctor/researcher then analyzes the reaction of the person towards the signals emitted based on the change in the person's EEG waveforms and compare them to EEG waveforms of patients with neuropsychopathic disorders such as schizophrenia, ADHD and mental retardation, to determine if the person has the said symptoms. In addition, the EEG/ERP system is used to test the degree of concentration amongst teenagers.
Key Features & Advantages
1. Professional EEG amplifier suitable for all standard applications of routine EEG and long term EEG monitoring in the research and clinical areas.
2. Configurable in a number of setups according to user's needs:
24/36/48/60 channels monopolar EEG;
24/36/48 channels monopolar EEG + 12 channels bipolar EEG;
24/36/48 channels monopolar EEG + 12 channels bipolar EEG + ERP examination with Acoustic & Visual stimulator, consisting of three stimulation functions (sound, light and electricity) which can be configured with special earphones and VEP monitor.
3.24 bits A/D conversion rate, with high sampling rate of up to 8 kHz.
4. High quality real-time EEG signal acquisition is transmitted via fiber optical isolation, which shields away interference from power line and other signals, transmitting stable and reliable measurement data at high-speed while greatly ensuring patient's safety.
5. Amplifier can be operated either by DC power without affecting signal quality.
6. Head-box design to access single shielded cup/clip electrodes with touch proof connectors (1.5mm).
7. Built-in impedance testing function and automatic calibration (for both sine wave and square wave signals).
8. Optional video system for recording, editing and displaying video images synchronously with EEG signals.
