g.Nautilus Multi-Purpose in combination with g.SENSOR fNIRS enables simultaneous recordings of EEG and fNIRS (functional near-infrared spectroscopy) signals. In combination with g.tec’s active EEG electrode technology, researchers get top-quality EEG recordings from 64/32/16/8 g.SCARABEO EEG channels and 8 fNIRS channels by using g.SENSOR fNIRS within a few minutes.
g.Nautilus Multi-Purpose wearable EEG headset is lightweight and highly robust to movement and challenging real-world experiments. It weights about as much as a climbing carabiner and has very small packaging. The g.Nautilus Multi-Purpose with g.SAHARA hybrid active EEG electrodes is well suited for remote locations e.g. high-altitude medicine and doesn’t require any hair washing. g.Nautilus Multi-Purpose with g.SCARABEO active EEG electrodes provide good contact between the head and the electrode, and less data artifacts which is crucial e.g. in sports science where subjects run and jump.
Wearable EEG headsets are becoming increasingly important in medical and clinical environments, since more and more studies are conducted in the field. Therefore, many different versions of g.Nautilus have been developed with a completely different design and a new standard of usability. The tiny and lightweight biosignal amplifier is attached to the g.GAMMAcap to avoid cable movements and to allow completely free motion. g.SAHARA hybrid active and g.SCARABEO active wet EEG electrodes provide users with top quality data 8/16/32/64 channels.
During alpine high-altitude expeditions, g.Nautilus Multi-Purpose wearable EEG headset can be used to record the physiological impact of high altitude on both EEG and ECG parameters. This is especially interesting for altitude medicine research.
