BrainAmp ExG MR
Overview
BrainAmp ExG MR: MR compatible bipolar amplifier with unparalleled design
The increasing interest in simultaneous EEG/fMRI recordings to investigate the brain’s activity very quickly led to the need to also co-register other types of physiological data such as bipolar and peripheral signals. The BrainAmp ExG MR bridges this gap and makes the recording of bipolar and polygraphic signals in the MRI environment a simple procedure.The magnetically shielded BrainAmp ExG MR system can be taken inside the magnet bore and placed right next to the experiment subject minimizing the length of the cables to meet all safety requirements.
The available MR compatible auxiliary sensors (GSR MR) are powered directly through the battery supplied amplifier which ensures patient safety and product portability.
The two existing versions with 8 or 16 channels can be purchased as extension to the BrainAmp MR and BrainAmp MR plus, but also as fully independent units.
