The NEURO PRAX DC-EEG system measures physiological signals such as EEG, EMG, and EP during non-invasive brain stimulation: specifically transcranial electrical stimulation (tES), tDCS, tACS, and tRNS.
NEURO PRAX DC-EEG
Unique amplifier technology captures activity from infraslow (0-0.3Hz) to ultrafast (80-1,200Hz) frequencies, while the large dynamic range and high sampling rate make the NEURO PRAX system particularly suitable for combined neuroimaging and neuromodulation techniques.
The combination of NEURO PRAX and the neuroConn DC stimulator with the Signal Out option now removes an artefact from the EEG during stimulation with alternating or random noise current (tACS-EEG / tRNS-EEG). NEURO PRAX uses an integrated, correction software to eliminate the stimulation-induced noise from the EEG signals.
NEURO PRAX is approved in the EU as a Class IIa Medical Device under the Medical Device Directive 93/42/ECC and has Class II FDA clearance in the US as a Biofeedback device.
