It's a scenario played out every evening all over the country: Come home from work and start venting to your spouse or roommate about your day. Instead of creating a negative atmosphere the minute you walk in the door, try starting off the evening with your family or friends by exchanging good news. Something good every day, you just need to recognize it.
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.
Isochronic tones work just the same in delta as they do in alpha, theta and beta and they are widely used in the brainwave entrainment community to help people sleep. Like you, I’ve also seen some websites saying they don’t work in delta, but it’s a bit like the game of Chinese Whispers, where someone makes a comment and then after it gets passed around and shared a lot the message gets distorted and appears to be a fact. I don’t know of any scientific reason why they wouldn’t work in delta. I remember some people talking about this on a brainwave entrainment forum many years ago. They were saying they found isochronic tones a bit too abrupt for using to help them sleep and they preferred binaural beats, as they thought they were a more soothing sound. That was just a personal preference shared by a couple of prominent forum members at the time and some people then took that as a fact for everyone. That’s where I think that belief originated from.
Magic happens with this amazingly deep meditation MP3. Delta stimulation can be very hypnotic, and Sub-Delta (0 – 1 Hz) in particular is theorized to have soothing effects on the limbic system, such as the amygdala and hypothalamus which themselves operate at delta frequencies. These neural structures are associated with emotions, fear, the fight-or-flight response, blood pressure, tension and more. Many people have found success using Delta as an aid in meditation. Using sub-delta to sooth these structures has resulted in amazing success helping health conditions such as fibromyalgia, chronic pain and hypertension (high blood pressure). Its soothing effects on the limbic system may shed some light on this.
Under the hands of the skilled massage therapist, massage can balance your hormones and reduce your stress. Many studies show massage therapy can reduce pain, reduce heart disease, reduce blood pressure, quiet the mind, and help repair muscular and tissue damage. During menopause, massage can help balance your hormones, reduce stress, and give you a little bit of alone-time to get your mind back under your control.
So if you are interested in using brainwave entrainment music in your own recording, do so with the knowledge that it can only help to improve the quality of your work. But please don’t feel as though your recordings will be insufficient without it (some people do worry about this - unnecessarily). My advice is that if you ever find yourself in a situation where the music you love the most is not available with brainwave entrainment frequencies, don’t ignore your intuition and discard that music. When you find that piece of music that brings your recording to life, go with it whether it has brainwave entrainment frequencies or not. The quality and feel of the music itself are the most important factors.
