The BrainAmp MR is a proven solution for simultaneous EEG/fMRI acquisitions.
The BrainAmp MR is a compact, modular MR compatible EEG amplifier consisting of 32 unipolar channels. Each 32 channel unit can be stacked to expand the number of channels up to 256 and 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.The BrainAmp MR system is powered by the rechargeable battery PowerPack, and can be used for many applications including the EEG lab for EEG/TMS co-registrations, EEG/ERP studies and Brain Computer Interface applications.
The BrainAmp MR can be placed directly inside the MRI chamber and placed right behind the subject’s head. The signal from the amplifier is then sent via optic cable to the USB interface located in the control room. This reduces the length of electrical connections and minimizes MR gradient artifacts and RF signal induction. The short length required for the electrical cables used to connect the electrode cap with the amplifier complies with all safety requirements for the experimental subject and reduces the chance for cable movement artifacts.
