BrainCap at a glance

• BrainCap is a fully customizable cap with up to 256 channels and high-quality Ag/AgCl sensors.
• Electrodes are fixed to the cap and extremely flat which makes BrainCap very comfortable for the subject (e.g. avoiding 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/fMRI (BrainCap MR), EEG/TMS (BrainCap TMS) and EEG/MEG (BrainCap MEG) are available.
• BrainCap is extremely handy, robust as well as easy and fast to clean after use.

BrainCap MR

Superior solution for combining EEG & fMRI

The technique of combined EEG & fMRI recordings has been evolving constantly over the last years. The electrode cap and electrodes, which are connected directly to the subject, are the items in our MRI product portfolio that more than the others require constant modifications, in order to guarantee always the highest safety and comfort of the test subject as well as to ensure an outstanding data quality both from the EEG and MRI point of view.

Guaranteed Safety

• All the electrodes in the BrainCap MR are fitted with serial current-limiting resistors.
• Safety resistors are also placed inside the cap connector, acting like an additional RF-filter.
• Electrode cables are routed on the outside of the cap and secured to it so that loops are not formed and cable movement is avoided.The drop-down electrodes (e.g. ECG, EOG, EMG) are additionally sheathed in plastic to avoid direct contact with the skin of the test subject.
• ECG electrodes do contain higher resistors than normal electrodes to compensate for the technical characteristics of longer wires.
• Wire length from electrode to the amplifier input is fixed to the minimal required length.
• Wire outlets for the cable tree at central positions avoid loops due to cable routing.
