By this point, it seemed like organoids with a living blood supply looked more like a human brain in terms of structure than they had ever looked in a dish because they were able to survive long enough to develop properly. However, the question still remained as to whether the neurons and their synapses were functional. Neurons are electrically excitable cells that receive, process and transmit information through electrical  and chemical signals. Calcium plays an important role in the transmission of electrical signals from one neuron to the next. Changes  in the levels of calcium at the end of neurons can be measured using calcium-sensing proteins that light up red. When the scientists looked through the glass window in the skulls of the mice, they were able to see that neurons did have fluctuating levels of calcium, suggesting that  neurons in the brain organoids were active. To be sure, they used electrodes to directly measure the electrical activity of the implanted organoid at different places and during different times of development, and discovered that the neurons were able to electrically stimulate each  other and respond to stimuli from the external environment.The researchers had succeeded in creating fully functional brain organoids. Then things got really interesting.

It’s the one thing that you actually have the power to change. There may not be a cure or a reliable way to reduce the volume, but you can change your emotional reaction to the sound and dramatically improve your quality of life. The Tinnitus Relief Project is an album of brainwave training audio tracks created to accompany the Rewiring Tinnitus book. 


Although most experts will tell you that people can get through the day without the production of Alpha brainwaves, that doesn’t mean there won’t be any repercussions. For people who have suppressed production of these brainwaves, they can end up developing anxiety disorders and other stress-related diseases, which can lead to the weakening of their immune system.

Let’s say you’re listening to a sound in your left ear that’s at a frequency of 132 Hertz (Hz). And in your right ear, you’re listening to a sound that’s at a frequency of 121 Hz. Your brain, however, gradually falls into synchrony with the difference — or 11 Hz. Instead of hearing two different tones, you instead hear a tone at 11 Hz (in addition to the two tones given to each ear).
I personally have been experimenting with binaural beats – both in and out of the float tank – for the past year or so and they have quickly and easily become one of my favourite go-to “hacks” for helping me achieve a desired state of being. From listening to a specific track right before going to sleep which helps put my mind and body in a state of relaxation and recovery to, on the flip-side, listening to a track that helps prime my brain-state for creativity and focus right before I sit down to do some work – like writing this blog! They are also an enjoyable and effective asset to try out and experiment with while in the float tank. For the reasons mentioned above, as well as the sound frequencies can resonate a subtle but noticeable vibration in the tank, water and your body making for quite the unique floating experience!
Exercise can help you balance your emotions and hormones. Primarily, and almost instantaneously, exercise helps burn through any additional cortisol and adrenaline that linger in your system. These stress hormones cause you to gain weight and put extra stress on your heart and mind. As you burn through the stress hormones, your body can rebalance the other hormones. Without the excess cortisol, your brain can begin producing higher levels of serotonin and dopamine. This can help reduce depression and anxiety while giving you clear thoughts and more focus.

Was wondering if you could give me a little more background on the suggested 2hr usage limit. I’m in LOVE with these CDs. Spent two months 2-3 times per day with ‘Equisync II’, and earlier this week shifted over to ‘Equisync III’. Since moving into Equisync III, I’m naturally drawn in my morning sitting to about 1 1/2 hrs with the tracks looping through my iPod. Then I sit again at night. I feel great. So is the 2hrs suggested for people with little prior meditative experience, is it a precaution for those whose psyche may be more fragile and prone to getting uber spacey and not managing their lives?


Another study found slight improvements in trait anxiety as a result of entrainment. It was noted that the study with the most successful protocol started at 30 Hz beta and ramped the frequency down until the person experienced relaxation for 15 minutes. This was then followed with a session of 8 Hz to 14 Hz for 7 minutes. The results suggested that 75% of individuals improved on their measures of long-term stress.
When work deadlines begin piling up and your social calendar is booked, the last thing you want to hear is to steer clear of the vending machine. Who has time for healthy eating? But when it comes to combating stress levels, what you eat may actually help relieve your tension. Indeed, some foods may help stabilize blood sugar or, better yet, your emotional response. Here, 12 foods to reach for when you've just about had enough.
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.

Everyone experiences stress, and not all stress is bad. However, individuals who experience acute episodic and chronic stress are at increased risk for developing stress-related health problems. This article outlines the relationship between stress and health and discusses the role of exercise in managing stress. Exercise recommendations and stress management tips are provided.
The effects are strongest while you are listening to the tones because your brainwaves are synchronized and tuned into the frequency range you desire at that time.  After you've stopped listening the effects can still linger for a while afterwards.  The timescale will vary from person to person and be affected by what you do after you've stopped listening.

With each pulsed tone, the brain produces an electrical response. The effects one experiences are the creations of the brains reaction to the “tones”, what neurologists call the “cortical evoked response” (the electrical response of the top most cortical layer of the brain). The brain is a mass of neurons, each taking part in storing, retrieving and transmitting electro-chemical impulses: information, colors, images, sounds, smells and tastes. Brainwave entrainment stimulates different areas of the brain allowing for the awakening and subsequent release of various levels of stored material. It also has an effect of  quietening the mind for clearer thought and process.
It is easy to see why religion quickly spread through culture once it emerged. When humans gained the cognitive capacity to reason and plan for the future, they became aware of their own mortality. The realization that oneself and all one’s loved ones will someday die is naturally terrifying, and this existential fear perfectly set the stage for anxiety-reducing ideas, like ones that offer a never-ending afterlife. But religions are complex ideas, and the psychological effects they have on minds go beyond just relieving anxiety.

Dissociative but not present. In college I started having difficulty with reading comprehension/absorption (not dyslexia, I could read everything out loud easily but not gather the meaning). Over the past two years or so, my memory has been concerning, as I am not middle or late aged. Since it had been getting worse, I have been researching for several years now for a cure. Biofeedback led me to neurofeedback (which I can’t afford at the moment).
So using the example track above, the right ear is sent a 20Hz beat, compared to a 10Hz beat in the left ear.  As the right ear receives the higher frequency of beat, this works to increase the speed of the ‘left' brain hemisphere, which can be helpful for people with conditions like ADD, who are often found to have an abundance of slow wave activity in the left brain.
Beta stimulation: There is evidence that stimulation within the beta range can improve attention, measures of intelligence, relieve short-term stress, decrease headaches, and decrease behavioral problems. Some evidence even suggests that beta could decrease emotion-based exhaustion. Many people with slower frequency brain waves may benefit from regular beta stimulation.
To use your senses to quickly relieve stress, you first need to identify the sensory experiences that work best for you. This can require some experimentation. As you employ different senses, note how quickly your stress levels drop. And be as precise as possible. What is the specific kind of sound or type of movement that affects you the most? For example, if you’re a music lover, listen to many different artists and types of music until you find the song that instantly lifts and relaxes you.
Some research suggests that the benefits from brainwave entrainment can last a lot longer, and still be seen for some time after you've stopped using it.  Study participants have still maintained improved test scores a few weeks after the stimulation had ceased.  Research on the long-term benefits has so far been minimal though, so how long the effects last is still up for debate.

Need a quick breather? Stressed to the max but haven’t got time to meditate? Then this 10 minute brainwave entrainment is the one for you! You will hear the gentle waves of the beach and sea gulls calling out, but underneath is a short 10 Hz relaxation session, ideal for stress relief or as a quick break from daily worries. Can be used with headphones or speakers.
When stress attacks, it can feel like your whole world is crashing down. Remind yourself what’s good in your life with a quick gratitude round-up. “Studies show gratitude techniques like counting your blessings can be a significant stress reducer,” Dr. Serani says. “Gratitude research reports that those who utilize daily gratitude reflections have higher levels of positive emotions, life satisfaction, vitality, optimism, and lower levels of depression and stress.” Reminding yourself of the good things in life can put stress in perspective. “Studies show that cultivating an optimistic mindset can help you maintain a positive mood,” Whitaker says. “When you are positive and grateful, you are able to handle difficult situations better.” Just look out for these stress relievers that actually backfire.
Alpha stimulation: Stimulation of alpha waves has been shown to provide stress-relief among employees, is able to provide pain relief, and improve measures of competence and recognition. If you have significant work-related stress, entraining certain alpha frequencies may help you decrease arousal and improve relaxation. Post-surgical stress doesn’t appear to benefit from alpha stimulation.
I forgot to tell you, after using your meditation for a few weeks, I woke up one morning with the most vivid recollection of having an out of body experience […shortened…] I am hoping to experience this again and control myself the next time. Thank you for enabling me to remember this extraordinary experience. I never believed they were real until I used your program.
When you're stressed, it can ratchet up anxiety hormones, such as adrenaline and cortisol. "The omega-3 fatty acids in salmon have anti-inflammatory properties that may help counteract the negative effects of stress hormones," says Lisa Cimperman, RD, of the University Hospitals Case Medical Center and a spokesperson for the Academy of Nutrition and Dietetics. In a study funded by the National Institutes of Health, Oregon State University medical students who took omega-3 supplements had a 20% reduction in anxiety compared to the group given placebo pills. One 3-ounce serving of cooked wild salmon can have more than 2,000 milligrams of omega-3s, double the daily intake recommended by the American Heart Association for people with heart disease.
Our everyday, waking brain used for active intelligence operates at approximately 13 hertz, which is in the range of high alpha or low beta frequencies. People who have certain learning disabilities and problems with attention often have low levels of 13 hertz frequency brainwaves in crucial areas of the brain used for sequencing tasks and doing simple math calculations. This is one concrete example of how brainwaves are associated with thinking and behavior. Each identified brainwave frequency has a different effect on a person’s ability to think, act, and feel.
In addition, Western culture reinforces thought and communication styles associated with the left brain hemisphere, which controls logic, language, and linear thinking in a majority of people, as opposed to the right hemisphere which controls brain centers for emotional, intuitive, creative, and non-linear thought processes. Note that a significant minority of people has the opposite hemispheric dominance than the majority of people.
If we want to inoculate society against the harms of fundamentalist ideologies, we must start thinking differently about how they function in the brain. An ideology with a tendency to harm its host in an effort to self-replicate gives it all the properties of a parasitic virus, and defending against such a belief system requires understanding it as one. When a fundamentalist ideology inhabits a host brain, the organism’s mind is no longer fully in control. The ideology is controlling its behavior and reasoning processes to propagate itself and sustain its survival. This analogy should inform how we approach efforts that attempt to reverse brainwashing and restore cognitive function in areas like analytic reasoning and problem-solving.
