NeuroField Q20 EEG



The NeuroField Q20 EEG amplifier reflects the state of the art in EEG signal processing.  The NeuroField Q20 is a DC coupled, 19 channel EEG amplifier. The Q20 is a sharp, clean EEG that has can used with the X3000 device to measure EEG in between pEMF (pulsed electromagnetic field) stimulation utilizing the real time z-score procedure in the NeuroField software platform. The Q20 has also been integrated in the Neuroguide 19 channel LORETA and Surface neurofeedback z-score platform.  Also, the Q20 has been integrated into the Bioexplorer software platform and can be used for standard neurofeedback procedures.  In this way the Q20 is truely a versatile EEG amplifier that combines pEMF and z-score neurofeedback technologies. The Q20 has a built-in rechargeable lithium battery. 


The NeuroField Q20 is a 20 channel,  DC  Coupled,  EEG amplifier.
