Proceedings of the 9th Conference on Interdisciplinary Musicology – CIM14. Berlin, Germany 2014 first group it increases, and for the second decreases. Experimental group did not fall asleep but maintained a relaxation state after the stimulus, while control group achieved unconscious relaxation but the effects did not hold. The STAI “State” indicated that stress increased after the stimulus for control group (see graph A1.2). 14. CONCLUSIONS • Delta (20-200) and theta (20-100) brainwaves are the ones that have greater amplitude (microvolts) in both groups. Results are clearly shown in graphs A1.5 and A1.10. Graph A1.5 Theta Graph A1.10 Delta • Higher frequency EEG waves such as beta waves have less amplitude. This happens because they are not synchronized and have more phase differences in both groups. • An increased alpha parameter is higher in the experimental group, which indicates that they achieved conscious relaxation. In contrast, the control group showed higher delta waves and presented signs of deep sleep during the experiment. Control group also possibly reached REM (Rapid Eye Movement) sleep halfway throughout the stimulus due theta waves presence in the EEG. • Beta waves are higher in the control group from s = 507 to s = 624 because of unexpected sounds in the stimulus (traffic noise appeared in the original recording). • Both stimuli induced relaxation, but it is important to point out that a person can relax without falling asleep. In this way the binaural stimulus worked better. • It is likely that the control group fell asleep with the nature sounds stimuli because lack of stimulation. • Contrary to what we expected, theta binaural waves didn’t induced FFR in experimental group, although they helped to achieve conscious relaxation. • Delta waves were higher in the experimental group during post-experiment measurements. This suggests that relaxation states were maintained with the absence of stimulus. • Presence of Alpha waves was reduced during deep sleep. This evidence is supported by the control group’s Delta values. • In the absence of stimuli, Delta wave values of the control group decreased, which means that relaxation effects did not prevail. • The effectiveness of an anxiolytic may be measured through the relaxation degree during stimulus and whether its effect endured or not. • For further evaluation of coherence [17] between brainwaves in both hemispheres and the ERP, the use of a 10-20 EEG system is recommended. • Post-experimental STAI “State” tests results are lower in the experimental group. This means that Theta binaural waves were a better anxiolytic than the stimuli (nature sounds) used in the control group. REFERENCES [1] Huang, T., & Charyton, C. (2008).

my daughter had an EEG and the neurologist said the brain wave activity in the back of her brain was very slow. I want to find out what causes this. She had a brain injury (3 skull fractures that were in the right side of her head and across the front right side. The fractures were closed wound. She had a small amount of swelling which diminished on it’s own. The neurologist asked if the fractures were in the back of her head and I told her no. She had no explanation for me.
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.
This is a brainwave meditation MP3 that will stimulate the Theta state of mind, allowing you to relax DEEPLY. On the surface you will hear a gentle rain and deep string sounds… underneath the MP3 uses a complex protocol which alternates stimulation between the left and right ears, and uses several ramps to reach the target brainwave frequency. It is useful for hyperactive people who have problems relaxing or entering trance like states.

Practitioners are discovering a number of different areas in which entrainment therapy may bring positive benefits. From managing mental health more effectively through to providing increased mental focus and concentration, it is thought the technique can be adapted according to the specific issues being treated. An improved immune system, enhanced levels of pain management, and a reduction in autoimmune disorders are also thought to be achieved through the therapy, leading many individuals with chronic ill health to consider brainwave entrainment as a non-invasive yet effective therapy.

Everyone experiences stress, and not all stress is bad. Individuals who experience acute episodic or chronic stress are at increased risk for developing stress-related health problems. Research supports the idea that exercise can improve the way the body handles stress, and it can provide a time-out from stressors. Exercise programs meeting the current recommendations for health included within a stress management program can be effective in stress reduction. However, it is important to consider the client’s stressors and physical activity barriers, activities the client will enjoy, and the exercise setting. Prescribing exercise for clients seeking stress management is recommended, but fitness professionals should recognize that some clients will need additional assistance for managing stress and major life stressors.
A high quality theta meditation MP3 specifically designed for restless, unsettled individuals. This Theta meditation, ramping in steps down to 6.5 Hz. It stimulates mid-Theta, so it may be easier to remain conscious during this session than with the deeper Theta meditations. This MP3 also uses a technique called Dissociation which is particularly useful for people who are restless and have trouble relaxing.
B6 is part of the B-complex vitamins and something you probably get an adequate amount of as part of a predominantly vegetable-based diet. However, during menopause, you may need to increase it more than your dietary intake allows. In this case, a low-level B6 or pyridoxine supplement can help give you a boost. In fact, taking a general B-complex supplement that includes adequate levels of B6 will provide you with an increase of all of the B vitamins, mostly because they work together.
The main gist of brainwave entrainment audios, without getting too technical here, is that they effortlessly guide one’s brain (when listened to with stereo headphones) into a specifically targeted state, as designated by the creator of the audio. They are able to alter your brainwave states through the use of specific audio frequencies, and specific beats-the most common of which being binaural beats (though there are other types of beats being used as well).  When one frequency is played into one ear- let’s say 1115 Hz- and a slightly different frequency is played into the other-say 1125 Hz- the brain is forced to reconcile the two, and creates its own “phantom” frequency that is the difference between the two- in this case 10 Hz.  Not only does this allow the brain to be led into specific brainwave states, but it also allows the two hemispheres of the brain to synchronize with each other, stimulating and promoting whole-brain functioning.

Isochronic tones are basically just a single tone with the volume being turned on and off at regular intervals. When you apply the same effects to music or a noise, it’s usually referred to as amplitude entrainment effects (in Mind Workstation anyway). When you apply the on/off effect to music or noise it’s usually done by targeting a specific frequency range in the sound and only turning that part on/off, leaving the rest of the music/noise untouched. What that does is allow parts of the music/noise to play without being distorted/interrupted, making it sound more pleasant to listen to. It produces a kind of fluttering sound as I like to call it and you can adjust the level of intensity.
Move your focus to the sole of your right foot. Tune in to any sensations you feel in that part of your body and imagine each breath flowing from the sole of your foot. After one or two minutes, move your focus to your right ankle and repeat. Move to your calf, knee, thigh, hip, and then repeat the sequence for your left leg. From there, move up the torso, through the lower back and abdomen, the upper back and chest, and the shoulders. Pay close attention to any area of the body that causes you pain or discomfort.
Our brains follow cues from outside stimuli, and brainwaves mimic the pulse rates of the sounds we expose it to. So, by creating tracks that pulse sound waves at a desired frequency, we can effectively coax our brain into that state. In layman's terms; by listening to some strange sounding brainwave frequency audios, we can literally slip our brain into a state of feeling calm, alert, focused, energized... and the list goes on. Pretty cool, right!?
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.
Stress affects your whole body, so find a pick-me-up for each of your senses. Turning on a favorite tune uses your sense of hearing for a science-backed burst of good feeling, and using aromatherapy uses your sense of smell to relax you. “Oils like lavender and lemon reduce stress,” Dr. Serani says. “Also, don’t forget that your sense of smell is the most nostalgic of all your senses,” so if you have a scent that reminds you of comfort, keep it on hand to sniff when you’re freaking out. Your sense of touch can be employed by stroking a “talisman”—a favorite or sentimental item—or even an “intention stick,” which you can hold like a wand to feel more in control. Chew gum to use your sense of taste to curb stress (scientists think it’s the lasting flavor, not just the act of chewing itself, that makes gum such a great stress reliever). Besides using your mind’s eye to visualize a happy place, you can use your sense of sight to look at calming images—cat videos on the Internet have actually been scientifically proven to lower stress.

Did you know that Past Life Regression can help you find your path to self discovery? People may explore a past life to help them gain an understanding of some of the issues that they are facing in this life. Oftentimes, there is a connection, a pattern of behavior, that has its roots in another time and in another place. If you are having trouble dealing with your everyday situation, The New York Hypnosis Center can help you. Through past life regression therapy you can address u…


Insomnia: Perhaps one of the most promising uses of brainwave entrainment technology is for those struggling with insomnia. While the technology is unlikely to provide a “cure” it may help those who have a high level of arousal or are “keyed-up” – reduce their level of internal arousal and sleep. Specifically insomnia that is induced by excess stress (e.g. beta activity) would likely benefit from slower wave stimulation (e.g. alpha activity) to aid the brain in transitioning into sleep.
Working out is one of the most effective stress relievers. Researchers recently found that after spending 30 minutes on a treadmill, their subjects scored 25 percent lower on tests that measure anxiety and showed favorable changes in brain activity. If you only have time to do one thing for yourself, make it sticking to your workout routines. If you can't hit the gym or trails, even a brisk 30-minute walk at lunch or getting up several times a day to stretch and walk around will help relieve stress.
No list is complete without exercise. Throughout our lives, exercise is critical for helping us maintain healthy bones, a trim figure, and balanced hormones. During menopause, many women gain weight. This is attributed to fluctuating hormones causing food cravings, fatigue causing less activity, and the body not adapting to the hormones and new lifestyle patterns.
Deemed as the “the most relaxing brainwave”, delta waves are at their most active when you’re not- they appear when you’re asleep and reduce your overall sense of awareness. Associated with the sub-conscious to unconscious parts of the mind, delta brainwaves are said to be the opening to non-physical states of reality. As a result, this brain state is most often seen while one is in very deep meditation or dreamless sleep.
***NOTE: (Last one) Please do research on which brainwaves do what before just trying out the first track you find! Also read descriptions of what frequencies are being used in the track, so you know what you are training your brain to! (Example: You struggle with OCD and have some anxiety. You see a track titled “Clear, Focused Thinking” and you try it out w/o reading the description. You either do not experience anything or you end up with worse anxiety/headache than before. If you knew before starting, that your problems were caused by too much Beta wave activity in your brain and the track was all low Beta ramping up to high Beta – you would not listen to it!)
Hi Marko, that isn’t one of my videos you referred to, so I can’t really answer you properly as I don’t know how their track was created. For the best answer, you should really contact the video creator. There isn’t any research that I’ve seen to suggest that you could harm your health by looping a delta track. During a typical sleep cycle, your brainwave activity will usually go up and down between the delta and theta range. It may be that you won’t experience the same quality of sleep if you spend most of your time producing mainly delta activity. With my 8-hour sleep track, I fluctuate the frequency range to try and emulate a typical sleep cycle http://www.mindamend.com/shop/sleeping-and-dreaming/deep-sleep-8-hour-sleep-cycle/.
Hi Ulka, thanks for your compliment on my article. Unfortunately, I haven’t come across any studies or much discussion about the problem with habituation and isochronic tones and how to overcome it. The consensus among experienced users is to regularly change the frequencies and music soundtracks you listen to. Adding music to the tones does change the waveform you are stimulated with, so that’s one of the main reasons why I provide different soundtracks for my isochronic tones sessions. I have released some tracks which use amplitude modulations in the music, instead of isochronic tones. It might be worth giving them a try if you haven’t already. I have them in a playlist on YouTube https://www.youtube.com/watch?v=Lj5tHl2cuWw&list=PLveg0IEcZWN6OIRZyLkv0BJADY7Q6xFCl.
Laughter releases endorphins that improve mood and decrease levels of the stress-causing hormones cortisol and adrenaline. Laughing tricks your nervous system into making you happy. Our suggestion: watch some classic Monty Python skits like “The Ministry of Silly Walks.” Those Brits are so hilarious, you’ll soon be cracking up, rather than cracking up.

When I am using equisync I feel kind of like it is “pushing me” – I guess this is the right way to say it- to achieve better results, which I really like. I fall asleep quickly, and sleep all night and even wake up before my alarm goes off. I feel noticeably calm during the workday- which is very helpful for what I do. I really like the warm feeling (my whole body gets really warm during my equisync meditation sessions) and I feel kind of like Im floating while listening. The soothing rainfall is also very nice.

This session shifts from the 14Hz sensorimotor rhythm through beta to 40Hz gamma, and repeats the pattern over and over, constantly “revving up” the mind with each repetition. The process is stabilized with a 10Hz background alpha beat, allowing the brain a place to relax instantly, whenever a let up allows. Use this session anytime, and for as long as required to get the job done. Take in a High Energy Espresso on long-hauls for a welcome lift. Works without headphones but the best benefits can be found with them. The session finishes at a fast, revving 18Hz beta. For use mainly with eyes open, engaged in an activity – with benefit to be gained from periodically closing your eyes briefly and relaxing.
