NEURO PRAX® EEG - 1

NEURO PRAX® EEG Measuring and Modulating Brain Activity Full-band DC-EEG biofeedback system NEURO PRAX® EEG systems measure physiological activity, such as EEG, EMG, and EP signals simultaneously and synchronously for all channels. The unique amplifier technology captures EEG activities from infraslow (0 - 0.3 Hz) to ultrafast (80 - 1,200 Hz) frequencies. Our full-band DC-EEG amplifiers are available with 32, 64 or 128 channels. The system provides a wide range of optional software-based functions, such as online correction of artifacts caused by muscle and eye movements, topographical analyses, spectral and amplitude mapping as well as online averaging. Thanks to the high-level dynamic range of the amplifiers, the NEURO PRAX® EEG system can be upgraded for use during transcranial electrical stimulation (tES) with direct current (tDCS), alternating current (tACS) and random noise current (tRNS), or during transcranial magnetic stimulation (TMS). In addition, it can also be used to take measurements during functional magnetic resonance imaging (fMRI). The NEURO PRAX® EEG supports patients to learn to self-regulate their brain activity (EEG biofeedback). It is intended to be used for EEG biofeedback with the slow cortical potentials (SCP) protocol in the treatment of children aged 7 - 9 with attention-deficit/hyperactivity disorder (ADHD).
