I'm not an expert on this exact subject, but my PhD was in computational neuroscience, specifically spiking neural networks, and I became a bit interested in the area of binaural beats. On exposure to binaural beats, neural networks in the brain can to synchronize in patterns that can be observed in EEG recordings (eg, Theta or Beta oscillations). So, while the science is conflicting and not settled there is plenty of actual research into this area.
