OpenBCI has a 4 Channel Inputs, with a 10/20 Scheme Placement

Steady state visually evoked potential. Induced by flashing lights. Frequencies: 8, 10, 12, 15 Hz

Initial Filtering with a Bessel Bandpass Filter (5 - 30 Hz), then goes through a Fast Fourier Transform (FFT)

Predictive Machine Learning Algorithm: Linear discriminant analysis (LDA), Training through calibration
