I believe the original algorithms were taken from this: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0130129
After studying the “My Virtual Dream” paper, I spent a few weeks creating my own version of the mellow and concentration algorithms. However, I’m not 100% happy with the outcome and I think I understand why Interaxon withdrew their versions. If you would like to try them out, they are hidden in Muse Monitor. To enable them, go to Muse Monitor’s settings screen and at the bottom, tap on the version number 10 times.
