However, unlike our own brains, which last a lifetime, these mini-brains are relatively short-lived. The human brain has the advantage of a circulatory system, allowing it  to  survive and function. By supplying brain organoids with a special cocktail of factors, they can grow in a dish, develop and survive, but  only to a limited degree. But, by transplanting brain organoids into the brains of living mice, one group of scientists has shown that artificially grown organoids have the potential to resemble a real human brain even more closely when they  are sustained by a living blood supply.
This session uses a proven technique for inducing deep relaxation, playing one frequency for two minutes, then alternating to a second after a 30-second ramp, then reversing the process. The first half of the session switches between a serotonin-boosting 10Hz and the grounding and rejuvenating 7.83Hz Schumann resonance. The second half of the session goes even deeper, alternating between the relaxing 7.83Hz and 6.3Hz, a frequency associated with releasing anger and irritability. The session ends on a chilled out 10Hz.
