Do Binaural Beats Really Affect Brainwaves?

Can the equipment detect differences between brainwaves, outside of binaural beats?

Have they run the same tests where they're trying to find the difference between someone resting (i.e. watching television) and someone being very mentally active (i.e. deep programming or whatnot)?

That would give an idea of how large the effect should be.

Yes, it can. We have used the same OpenBCI board and software in other experiments, and it does show changes — for example, I ran OpenViBE’s demo SSVEP scenario on the same subject, and the spectrogram showed a pattern of increased amplitude that correlated with the target frequencies.

Even if the effect was too small to see in the spectrogram, we should have seen some affect in the FFT plot at the target frequency; instead, the amplitude of the trials at the target frequency were very slightly below the amplitude of the control segments.
