BrainAmp ExG MR

Capture high-quality polygraphic, bipolar, and auxiliary physiological data directly inside the MRI environment with a compact, MR-conditional amplifier designed for safety, portability, and seamless integration with the BrainAmp MR plus.

Key system highlights

True bipolar
Recordings
Outstanding signal quality with true bipolar recording capacity
Stand Alone 
System
Available as stand-alone version for labs focusing on peripheral signal acquisition
Multimodal

The Extra - Add on

The BrainAmp ExG MR extends simultaneous EEG/fMRI research by enabling the acquisition of bipolar, polygraphic, and peripheral physiological signals directly inside the MRI environment. Designed for use alongside the BrainAmp MR product family or as a standalone solution, it provides researchers with a flexible platform for recording additional physiological measurements without compromising data quality or safety*. Like all BrainAmp MR amplifiers, the BrainAmp ExG MR is positioned close to the participant inside the MRI scanner room, minimizing cable lengths to reduce artifacts and improve signal integrity. This compact setup also supports compliance with MR safety requirements while simplifying system installation and operation.

*Safe recordings with BrainCap MR, R-Net MR, and BrainAmp MR amplifiers (MR, MR plus, ExG MR) require close adherence to Brain Prdoducts' safety instructions.
