In a 2016 interview, organoid pioneer Madeline Lancaster at the Medical Research Council Laboratory of Molecular Biology in Cambridge, England said of her 3D brain tissue structures, “Just to be clear, they are not really human brains.” At the time, she was able to recall 16 labs around the world who had adopted her technique. But did she foresee that a year later, other labs would be injecting them into mouse brains? If neural networks are at the root of consciousness and if we don’t fully understand how consciousness arises because of them, do we need to consider the ethical implications of producing brain organoids, which are becoming better and better at forming functional connections? The president of the Allen Institute for Brain Science in Seattle, Christof Koch, has concerns, saying in an interview last year “We are entering totally new ground here. . . the science is advancing so rapidly, the ethics can’t keep up.”
I can offer a hypothetical--however do not know know practical it will turn out to be. There is a fair amonut of bad science on this topic on you tube. The gamma wave frequency is associated with attentional focus and arguably a unified sense of self. If it could be entrained it should lead to a meditative focus-like exceptionally well-trained meditators. Some but not all studies on meditating Buddhist monks suggest this is so. Does this really and more generally occur--I will say there is nothing lost in trying--we all go into a 40Hz range on occasion without ill effect-- but I would not put confidence in the purported methods out there at present. Good luck.
Progressive muscle relaxation is a two-step process in which you systematically tense and relax different muscle groups in the body. With regular practice, it gives you an intimate familiarity with what tension as well as complete relaxation feels like in different parts of the body. This can help you react to the first signs of the muscular tension that accompanies stress. And as your body relaxes, so will your mind.
Listen to the gentle rain fall as this brainwave MP3 ramps slowly down to the deepest Delta levels. This is one of the deepest brainwave entrainment meditations you will find. Many people using this session will fall asleep, since it resembles the sleep induction sessions. It differs from sleep induction in that there is an upward ramp at the end to help bring you out of the Delta state before the MP3 is completed. Delta Meditation with rain can be listened to with speakers or headphones.
There's a reason this place has been voted the best salon in the Capital Region for a number of years. Christopher and his team are THE BEST. It took me years to find a place I trusted with my hair in the Albany area, but after finding CBS I am a customer for life. I usually get my hair done by Stacy and she is excellent at listening to my ideas and 1) telling me why some of them are not the best for my hair and 2) giving me a cut and color that I LOVE every single time. On top of that, she is extremely pleasant and makes the time you spend in her chair fun and engaging.
“Brainwave entrainment has powerful benefits, that's clear. But most brainwave entrainment CDs tend to be non-specific, across the board. What if you want to achieve one particular state, 'cos that's what you need right now? That's possible with these Brain Salon sessions! You want to chill out, get ideas, go to sleep, feel energized or happy, or get 100% mentally switched-on - just listen to the session and you've got it! You 'get the hang' of these states too, so after enough practice you don't even need the brainwave entrainment CDs to control your own mind. It's worked for me, and I'm sure will do the same for you too.”
The studies included in the recent reviews of Tai Chi and yoga indicate that sessions between 60 and 90 minutes performed 2 to 3 days per week were effective in reducing stress and improving feelings of well-being (7,14,17). A study conducted in a worksite environment showed that 15 minutes of chair-based yoga postures was effective in reducing acute stress when assessed by self-report and with physiological measures (e.g., respiration rate and heart rate variability parameters). This finding indicates that shorter duration sessions can be effective in reducing acute stress with this type of exercise (15).
Really great stuff here, man. Well done! Without taking anything away from the article it would have been great to have under one “roof” similar information about hypnotherapy and subliminals. I invested quite a lot in buying binaural cd’s but after reading your material I think that for short term effects isochronic tones rather than binaurals are the technology to go for now. For longer lasting and possibly permanent effects I’m not sure whether I should go for hypnosis or subliminals (or both). An article as well written and comprehensive as yours but focusing on hypnosis vs subliminals would have completed the circle for me. The stuff I’ve read so far on binaurals vs isochronics hasn’t really done it for me. Any chance you could give it a shot?
Theta waves have another interesting characteristic. The Earth has a measurable resonance of 7.83 hertz known as the Schumann resonance. Because the Schumann resonance is a constant background frequency surrounding all life, it may play a special role in biological activity. The Schumann resonance frequency falls within the range of theta brainwaves and may have something to do with why these brainwave frequencies are so powerful.
The most common way to use a brainwave entrainment is for a short-term benefit, to help guide your brain into a particular mental state at the time you need it. In a similar way to how you might take a sleeping pill before bed to help you get to sleep, or maybe drink some coffee or an energy drink to help wake you up and give you a boost of energy.
Physical activity can pump up your feel-good endorphins and other natural neural chemicals that enhance your sense of well-being. Exercise can also refocus your mind on your body's movements, which can improve your mood and help the day's irritations fade away. Consider walking, jogging, gardening, housecleaning, biking, swimming, weightlifting or anything else that gets you active.
Attention and learning ability has been suggested to improve as a result of beta stimulation protocols. Research has shown that beta waves tend to be deficient among those who have learning disabilities and/or attention deficits. Other research with photic stimulation determined that stimulating 14 Hz and alternating it with 22 Hz over several sessions produced significant GPA improvements.
Deep relaxation is another major benefit resulting from the brains cortical frequency following response while using brainwave entrainment. As the brain tends to mimic the rate of frequency it is exposed to, thus allowing it to enter into that brainwave state, this helps explain why this technology can produce benefits commonly found with meditation.
An invigorating, brain-sharpening session, this audio starts at 14Hz, a beta feel-good frequency, and SR harmonic. It then steps up in six-minute harmonic increments, gradually up to gamma 39Hz, leaving you feeling mentally stimulated and full of energy. A binaural beat track supports the main frequencies for those wearing headphones. Uplifting background music with embedded amplitude modulation provides a further layer of entrainment. Excellent for use as a morning alarm clock, ahead of a big night out, or to inspire those tired trips to the gym.
