Transparent Corp's Research Area is arguably the most comprehensive resource for collated brainwave entrainment research. Update: the main research area on Transparent Corp's website is currently being updated, so it is offline. However, you can still access their peer-reviewed research paper as a PDF here: “A Comprehensive Review of the Psychological Effects of Brainwave Entrainment“.
I also believe that the dangers of brainwave entrainment should be further explored as well. There are relatively vague benefits, but it remains unclear as to whether entraining certain frequencies may be detrimental to performance or induce harm. Despite the fact that brainwave entrainment has existed for a long term, it remains an understudied niche in neuroscience.
The next day, Anabel watches the tournament being hosted at the Battle Dome, where Emerald is challenging to obtain his fifth Symbol. As Emerald battles Tucker in the finals, Scott asks Anabel to talk with him somewhere else. This Scott is revealed to be a disguised Guile, who puts Anabel under mind control. After this, Guile returns to the Battle Dome, where he manages to find and capture Jirachi. Guile uses the rental Pokémon to attack innocent bystanders and heads to the Battle Tower to make his wish. Emerald, Noland, Ruby, and Sapphire all head to the Battle Tower to stop Guile, but are forced to traverse the Battle Tower's seventy floors and challenge Anabel on the final floor. Emerald manages to get to Anabel first, but is defeated by the time everyone else arrives.
As you close your eyes, this session quickly lulls you down into deep delta sleep, where the body recovers and grows. The session starts at a waking frequency, soon taking you down deep into delta, with stops at sigificant beneficial frequencies such as the de-stressing 10Hz, the grounding 7.83Hz Schumann resonance (SR), and the deeply relaxing 5.5Hz. You’ll soon find yourself in a deep, healing sleep. If you’re particularly stressed, try listening to Power Chill before starting
