The OpenBCI Headband kit is a great starter kit for EEG measurements! Researchers, teaching labs and classrooms will find this budget-friendly option appealing. The leads included are compatible with all OpenBCI biosensing boards: Cyton, Ganglion, and CytonDaisy. Boards sold separately.
The leads are all 18" (45 cm)
The headband allows three frontal cortex measurements (F7, AF7, Fp1, Fpz, Fp2, AF8, F8) via the 3 lead wires with flat EEG electrodes. The two leads with spikey electrodes will allow measurement at the FT7/FT8, T7/T8, TP7/TP8, P7/P8, PO7/PO8, O1/O2, and Oz nodes, depending where you insert the spikey electrodes. In total, this kit comes with FIVE electrode leads, with option to add more!
