The NeuroField technology incorporates very low intensity, pulsed electromagnetic field (pEMF) stimulation, heart rate variability (HRV) and electroencephalography (EEG) all in one biofeedback system. The NeuroField X3000 is a four channel frequency generator that can generate pEMF frequencies from 0.31-300,000 Hz. The pEMF output ranges from 1-40 microtesla.. NeuroField low intensity pEMF is 10,000,000 times weaker than traditional rTMS (transcranial magnetic stimulation) which was approved by the FDA in 2008 for the treatment of depression. The NeuroField Q20 is a DC coupled, 19 channel EEG amplifier. The Q20 is sharp, clean EEG that has can used with the X3000 device to measure EEG in between pEMF 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. In this way the Q20 is truely a versatile EEG amplifier that combines pEMF and z-score neurofeedback technologies. NeuroField was founded and invented by Nicholas Dogris, Ph.D. and Brad Wiitala, EE. NeuroField has evolved into the first pEMF device that measures physiological responses through EEG and HRV. Furthermore, NeuroField pEMF uses norm referenced, z-score, data to guide the brain to a regulated, normative state. As a result of these innovations, NeuroField brings the science of low intensity pEMF into the clinical setting.
