BrainAmp MR plus
Overview
BrainAmp MR plus extends the borders of the technically possible
Since the design of the first BrainAmp MR, the neurophysiology research world moved forward and started to look at new techniques of investigating the brain in action. In light of this it was obvious that there was a need to develop a more advanced amplifier which could cover a wider range of applications and be as flexible as required by its users.
The BrainAmp MR plus enhances the already outstanding features of the BrainAmp MR thanks to the multiple hardware signal resolution options settable via the recording software. Based on the recording needs, with just one “click” it is possible to switch from AC to DC mode acquisitions as well as to extend the hardware bandwidth.
The result is an amplifier that can be placed inside of the MRI bore for simultaneous EEG/fMRI acquisitions as well as used in the EEG lab for EEG/TMS co-registrations, EEG/ERP studies and Brain Computer Interface applications. There is no need for different amplifier types as the Brain Products’ flagship represents the state of the art solution for all of the aforementioned applications.
BrainAmp MR plus systems can be stacked on top of each other to increase the number of available channels up to 128 for recordings in the MRI environment and up to 256 channels for laboratory applications. Powered with rechargeable batteries, this amplifier can be used in any environment even for outdoor recordings. The BrainAmp MR plus system can be combined with the BrainAmp ExG MR amplifier to record EEG, EOG, EMG, ECG, GSR (Galvanic Skin Response) and many other types of bipolar and auxiliary signals.
