Despite some interesting new developments in the area of EEG Recording Caps like sponge-and-saltwater-nets or dry-electrode-headsets, the majority of EEG research is still done with electrolyte-gel-filled-electrode-caps. Easycap manufactures caps with any channel number, any layout and for connection to any amplifier. This is not only for recording EEG alone, but also for recording EEG simultaneously with other data acquisition technologies like fMRI, MEG, NIRS, or during TMS or AC/DC stimulation. The caps come with active or passive electrodes, or with electrodes optimized for specific technical requirements. We have also designed special caps and belts for mobile EEG.
The variety of applications results in a multitude of different caps. So, in everyday life one is mainly concerned with which cap for what, or which cap do I need? This overview is organized around these important questions.
