Cool meta-analysis study about the proven benefits of Frequencies and Binaural Beats in meditation... on memory, creativity, attention, anxiety, mood, and vigilance...

I wish they had included a bit more data about the sample and effect sizes in the article. I'm still puzzled whether any of the stimulation methods had a robust effect that had consistent effect over several studies.

Thanks for sharing!
