Binaural beats require two separate tones from two sources that are combined inside the listener’s brain to form the target tone. The lower frequency sound is called the carrier tone, and it is combined with a higher frequency sound known as the offset tone. Because of this, binaural beats must be listened to with stereo headphones or the effect is lost. Binaural beats create a hypnotic effect, but they are not the most effective tool for brainwave entrainment, and binaural beats are often ineffective for people with hearing loss.
“Mini-brains,”  or brain organoids, the latest development in stem cell technology, are organized 3D cell structures made up of different brain cells, which resemble the complexity of the human brain. Human stem cells can be  grown into brain organoids in 40 days, offering neuroscientists an  unprecedented opportunity to more accurately model human brain  development and disease. Until now, scientists had two choices: to study the brains of other mammals and extrapolate similarities with the human brain, or study the cells that make up the brain in a dish, which  although informative, can only tell us so much about how the human brain  works as a whole.
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
