NEURO PRAX MRI-EEG

Using unique amplifier technology, the NEURO PRAX MRI EEG captures EEG activity from infraslow (0-0.3Hz) to ultrafast (80-1,200Hz) frequencies, while the large dynamic range and high sampling rate make the system particularly suitable for MRI-EEG applications.

The NEURO PRAX MRI EEG system is well suited to recording and analysis of cortical and sub-cortical EEG activity; investigation of functional connectivity between areas of the brain; fMRI and evoked potentials, fMRI and galvanic skin response, and fMRI and facial EEG; quantitative EEG analysis and cognitive evoked potentials during fMRI; and fMRI and DC-EEG feedback investigations.

The system is compatible with the neuroConn DC-STIMULATOR MR for combined multimodal imaging with neuromodulation (tES-MRI-EEG).

NEURO PRAX MRI 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 USA as a biofeedback device.

MULTI CHANNEL OPERATION

The NEURO PRAX MRI EEG offers up to 128 unipolar channels with up to 4kHz sampling rates.

ACTIVESYNC

Passive clock frequency calculation using ActiveSync to accurately synchronise with MRI.

ARTEFACT CORRECTION

Online correction of pulse and gradient artefact during fMRI.

CE AND FDA APPROVAL

NEURO PRAX MRI 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 USA as a biofeedback device.
