The NEURO PRAX® EEG system is a full-band, modular DC-EEG used in neurological diagnostics. These direct current EEG systems measure many physiological signals including EMG, EEG, and EP in the 0-1200 Hz frequency range synchronously and simultaneously for all channels. Infraslow EEG activities (0-0.3 Hz) to ultrafast EEG activities (80-1200 Hz) are captured with the special amplifier technology. The full-band, high-performance DC amplifiers can be supplied with 32-256 channels. It includes software that is easy to use, flexible, and specially tailored to your hardware. The device has all the features of conventional EEG/EP devices and can also be extended to create a complete system capable of polysomnography, invasive measurement during surgery, long-term monitoring using videometry, neuro and biofeedback, measurements during MRI (Magnetic Resonance Imaging) fMR, and simultaneous transcranial stimulation (TMS).
