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  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  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.
This has been a very inclusive and helpful blog. You have covered all the different means we have to help us get through the whole menopause process. It takes a combination of all the means suggested in your article, not just one. Eating of fresh fruits and vegetables is so important. Taking of the Magnesium supplement has been most helpful, to me, along with time for meditation/prayer. We have soooo many things available to us to help us through this short sometimes difficult period in our lives. Take advantage of the suggestions in this great article.
Much of what is currently written about brainwave entrainment, especially on the internet, is simply … incorrect. It seems par for the course that when something of huge value is discovered as a potential ‘internet product’ that it is going to be marketed within an inch of it’s life. And often with less than stellar regard for actual science, research, or factual knowledge.
- Added the ability to create a playlist of your own iTunes library music and use it as the background. The behavior of the app when iTunes music is used instead of the included ambience is slightly different so please review the help. Notably, unlike our included ambience which can be played at a volume below the device volume, iTunes music can only be played at the device volume. So when playing iTunes music the Ambience volume slider disappears.
Since the beginning of the 21 st century, there has been a great development in different studies related to encephalography and the psychological consequences of binaural audio. The objective of this paper is to analyze the effects of binaural audio as a relaxation method for people that suffer anxiety and stress. The study took place at ITESM, Santa Fe Campus, where twenty participants around 21 years old took part of the study. They were divided into two groups, Experimental and Control. The first one listened to the Theta binaural stimuli and the second one listened to a stimulus with nature sounds (birds and wind). The results show that the experimental group got to conscious relaxation. The control group had an unconscious relaxation (sleep), but when the stimuli stopped they recovered their stress level, for some participants it increased.
