For recording polysomnography in the lab, our all-in-one lab amplifier and low-profile, slim, active electrodes allow for comfortable, long-term high-density recordings with the ability to add many peripheral and auxiliary sensors. Alternatively, for sleep recordings outside of the lab, our mobile amplifier, combined with an external power source and additional sensors provides a portable setup, so your participants can sleep in the comfort of their own home. Make use of sleep-scoring tools within our analysis software for manually marking your sleep stages for further analysis. Additionally, fully synchronized video and EEG recordings are made possible with a network camera using infrared illumination.
