BrainAmp MR

BrainAmp MR: Superior solution for combining EEG and fMRI

Over the course of the last number of years the combination of EEG and fMRI to investigate the electrophysiological as well as the hemodynamic information of cerebral dynamics has become an extremely popular technique. The first BrainAmp MR system for EEG/fMRI simultaneous acquisition was manufactured by Brain Products almost 7 years ago and it represented a real technological breakthrough.

The extremely high data quality, ease of use, long lasting experience of our developers and the unparalleled scientific and technical support made the BrainAmp MR amplifier the first choice for researchers all over the world. Many scientific publications refer to EEG/fMRI coregistration studies performed with the BrainAmp MR systems.

Technical reasons for the great success achieved by Brain Products with this system are as follows:
The BrainAmp MR is a shielded amplifier which can be taken directly inside the MRI chamber and placed right behind the subject’s head. From the amplifier the digitized signal is sent via fiber optic cable to the USB interface located in the control room. Therefore no artifacts can be added along the way to outside of the MRI chamber. 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.

The sturdy and compact BrainAmp MR can be stacked one on one to acquire up to 128 EEG channels with ease. The MR compatible rechargeable batteries make this system a truly portable solution even for outdoor recordings.

The BrainAmp MR can be combined with the MR compatible ExG amplifi ers to add the capability to record bipolar and peripheral signals (e.g. Galvanic Skin Response) in an extremely compact setup.
