The Ultracortex is an open-source, 3D-printable headset intended to work with any OpenBCI Board. It is capable of recording research-grade brain activity (EEG), muscle activity (EMG), and heart activity (ECG). It is not designed for transcranial stimulation. This headset is designed to receive EEG signals only. The Ultracortex Mark IV is capable of sampling up to 16 channels of EEG from up to 35 different 10-20 locations.
The Ultracortex Mark IV is the latest edition of the Ultracortex—a comfortable, adjustable, and 3D-printable EEG headset, compatible with all of the OpenBCI boards. The Ultracortex’s revolutionary design uses dry EEG sensors and takes less than 30 seconds to put on and get up-and-running (check out the video demo below). Included is the free GUI application for streaming live data.
