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 already many 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 co-registration studies performed with the BrainAmp MR systems.

The BrainCap is a fully customizable cap with up to 256 channels and high-quality Ag/AgCl sensors. The electrodes fixed to the cap are extremely flat. This solution is very comfortable for the subjects as it avoids excessive pressure onto the scalp, even in sleep studies during which the subject lies on the electrodes.

Specially designed electrodes for the co-registration of EEG/MEG and

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, which is powered by the rechargeable battery PowerPack, can be stacked one on one to acquire up to 256 EEG channels.

The BrainAmp MR can be combined with the BrainAmp ExG MR amplifiers to add the capability to record bipolar and peripheral signals (e.g. EOG, ECG, EMG, GSR - Galvanic Skin Response, etc.) in an extremely compact setup.
