NEURO PRAX MR*

The NEURO PRAX® MR* is a full-band DC-EEG system, which is primarily intended for use in neuroscientific applications. The system measures physiological signals such as EEG, EMG and EP in the frequency range of 0 to 1,200 Hz 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.

The high amplifier dynamics and the integrated real-time correction of gradient artifacts and pulse artifacts make the NEURO PRAX® MR* system particularly suitable for measurement during magnetic resonance imaging (fMRI).

We can supply our high-performance full-band DC amplifiers with 8, 32 or 64 channels. The neuroConn software, specially tailored to the hardware, is intuitive, flexible and easy to use. There are a large number of software and hardware modules available, such as online correction of artifacts caused by muscle and eye movements, topographical analyses, spectral and amplitude mapping as well as online averaging.
