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, or for sending any kind of signals. 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.

Ultracortex Mark IV Product Highlights
We have very high expectations for the Ultracortex Mark IV. Improvements from the Mark III include:
Higher node count (especially above motor cortex & visual cortex). The Ultracortex Mark IV will be able to target 35 electrode locations of the 10-20 System, as depicted in the diagram below
Maximum comfort for prolonged recording
Simplified assembly and adjustability (based on feedback from our Mark III customers)
Secured electrode cabling for reduced noise and improved aesthetic
One of the great things about the Ultracortex design is how fast it is to get it up-and-running. Adjusting the headset for different head shapes and sizes is easy. All you have to do is twist the nut in the electrode holder. Once you adjusted the electrode holders at the various frame nodes, you can put the headset on and get up to 16 channels of EEG data streaming in under 30 seconds. Check out the video below!
