Brainwave Entrainment - a New Way for Relaxation and Healing Has Right Or Left Hemisphere Dominance 24/07/2019 Brainwave Entrainment - A new way for relaxation and healing has right or left hemisphere dominance. Understanding Brainwaves In order to understand why brainwave entrainment is successful for achieving relaxation, reducing anxiety, and aiding in so many other ways, understanding brainwaves is essential. The brain is composed of millions of specialized cells called neurons. Neurons send signals to other neurons using electro- chemical messengers called neuro-transmitters that attach to receiving sites located on the neurons themselves. There is a space between the end of the neuron and the receptor called the synaptic gap. As neuro-transmitter chemicals move across this gap, a small electrical charge is created. These myriad chemical interactions occurring all over the brain at the same time produces electrical waves of specific frequencies that can be detected at the surface of the skull and are called neural oscillations or brainwaves. Brainwaves change and vary in frequency depending on what activities we are doing with slower waves being produced during sleep and faster waves occurring during periods of activity and mental focus. Everyone has all forms of brainwaves in different amounts and at different times. While a practical understanding of brainwaves has been around for as long as people have been singing, chanting, and drumming, a scientific view of the electrical activity inside the human brain was not published until 1924 when German psychiatrist Hans Berger developed a machine for sensing and recording activity in the brain by attaching small electrical sensors to the scalp of his patients and recording the resulting electrical activity. Berger’s inventions and discoveries were built upon the earlier work of Richard Caton who published animal studies on brainwave oscillations in 1875. With digital upgrades, Berger’s machine is still in use today, known as an electroencephalography machine, or EEG. Berger used his machine to study the brains of psychologically normal and abnormal people and discovered the first brainwave, called the alpha wave and also known as the Berger wave, along with the faster beta wave, which he observed suppressing the alpha wave when subjects opened their closed eyes. Today, EEG machines are used for diagnosing epilepsy and sleep disorders, for determining dosages for anesthesia, and measuring the brain activity of people in comas or suffering from brain trauma. EEG machines also continue to play a role in researching and understanding brainwave entrainment and developing new and better methods for delivering the benefits of this form of brainwave modification. Brainwaves are the collective electrical signal of millions of neurons working together in a living brain, producing our sense of alertness – or lack thereof - and producing our experience of reality. As brainwaves change, so does our perception of the world and our inner perception of ourselves. By learning to control our brainwaves, we can achieve specific, desirable mental states, such as feeling more relaxed, less anxious, more creative, more focused, or sleepier. Brainwave Patterns and Corresponding Mind States Brainwaves frequencies are known by the names of Greek letters of the alphabet. From the lowest frequency, they are: Delta - 0.1 to 4 hertz Theta - 4 to 7.5 hertz Alpha – 7.5 to 12 hertz Beta - 12 to 30 hertz Gamma - above 30 hertz Each of these brainwave types differs from the others in the frequency, or cycles per second of oscillation of the wave. Brainwave frequencies are measured in hertz, and one cycle per second is defined as one hertz. 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. All brainwave frequencies are useful and beneficial at certain times – there is no brainwave that is intrinsically better than another. However, by deliberately choosing to attain a particular brainwave state, a corresponding mental state can be brought about at the same time. For example, a working person who has been in an overly alert beta brainwave pattern for many hours can quickly shift their mind and body into a relaxed state by listening to a few minutes of brainwave entrainment music for inducing alpha or theta brainwaves. Here are details about each brainwave state and the states of mind associated with each: https://www.brainwave-music.com/brainwave-entrainment.html 3/12 24/07/2019 Brainwave Entrainment - A new way for relaxation and healing Delta Brainwaves Delta brainwaves have the slowest frequencies, ranging between 0.1 and 4 hertz, and these are the brainwave states associated with deep sleep, trance states, and unconsciousness. Few people can remain awake during delta brainwaves states, although this state is recorded in awake infants between ages of three months and one year and also in babies just before birth. Delta waves are also linked with increased production of HGH, DHEA, and the neuro-transmitter serotonin. When delta waves are present, our awareness of the external world decreases and shuts off. People with ADD have problems with delta waves occurring when they are trying to focus, and focus and attention become increasingly impossible with stronger delta waves. Studies show a reduction of anxiety, improvements in insomnia, and elimination of headaches when people engage in sessions of delta brainwave entrainment. Theta Brainwaves Theta brainwaves are next highest in frequency above delta and are especially important for many people using brainwave entrainment and meditation because theta waves are at a threshold, forming a link between wakefulness and the subconscious mind. Theta waves bridge between our awake self and the creative and insightful understandings from below our conscious awareness, and while they are not common in awake adults, they are normative for children under 13 years old. Theta waves have a frequency between 4 and 7.5 hertz, making them slower than more wakeful alpha but faster than the dreamless slumber of delta. Theta brainwaves are the frequencies of nighttime dreams and REM sleep when the brain goes through bursts of activity and eye movement. People also experience theta waves in a state of light sleep, deep relaxation, during meditation and prayer, and when daydreaming. Theta waves produce an experience of inward wakefulness where we become disengaged from the outside world while engaging in inner activity. At the lower frequencies of theta, sleeping states are experienced, and at the higher range of frequency, awake relaxed states are experienced. 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. Theta brainwaves in the frequency range of 6 to 9 hertz are known as thalpha waves because of their proximity to alpha waves. They are seen during states of high suggestibility, during hypnosis, and during paranormal experience and are also connected to an increase in human growth hormone (HGH) levels and higher blood flow to the brain. Theta brainwaves sit between the realms of the subconscious and conscious mind, making them an especially useful brainwave state for developing creative thinking, working through emotional problems, and integrating subconscious and conscious experience. Theta waves also have been observed in moments when a person recalls information from the past, and this may be what links them also to improvement in learning ability. We also experience theta waves when we go into automatic pilot mode, such as when doing a repetitive task like driving a familiar route where the mind become disconnected while you still drive safely toward your destination. People who suffer from anxiety or frequent periods of stress often find theta wave music an effective means for quickly relaxing and unwinding. At the slower frequencies, theta tuned sounds can induce sleep, bring on lucid dreaming, and provide a deeply relaxing and rejuvenating experience. Scientific studies of theta brainwaves find they are especially useful for reducing anxiety, inducing hypnotic states of mind, and entering the brainwave patterns associated with meditation. Alpha Brainwaves Alpha brainwaves are perhaps the most well-known brainwaves, being the first discovered and named by Berger, and also because they are commonly occurring brainwaves of a light, alert state of mind which our brains naturally rest at when awake, stress-free, and engaged with the world or our own thoughts. Oscillate at a frequency of 7.5 to 12 hertz, these are the brainwaves present when a person is relaxed and awake, occurring often at the time a person wakes up and is transitioning from asleep to awake and also present when a person is awake and engaged in creative thinking or action. Many people experienced in using alpha brainwave entrainment

Furthermore, it can be used for relaxation and sound massage without the need for a second person. The eBowl generates auditory beats that are in EEG alpha frequency range, which can cause brainwave entrainment and lead to relaxation. User tests measuring Figure 1.

Andrews, CS 2012 Mark E. Hayden, ECE 2012 Date: 16 December 2010 Professor Frederick W. Bianchi, Advisor Abstract The brain performs a vast amount of processing to translate the raw frequency content of incoming acoustic stimuli into the perceptual equivalent. Psychoacoustic processing can result in pitches and beats being “heard” that do not physically exist in the medium. These psychoac- oustic effects were researched and then applied in a large scale sound design. The constructed installations and acoustic stimuli were designed specifically to combat sensory atrophy by exer- cising and reinforcing the listeners’ perceptual skills. i Table of Contents Abstract ............................................................................................................................................ i Table of Contents ............................................................................................................................ ii Table of Figures ............................................................................................................................. iii Table of Tables .............................................................................................................................. iv Chapter 1: Introduction .................................................................................................................

    NeuroRegulation http://www.isnr.org The Effect of Infraslow Frequency Neurofeedback on Autonomic Nervous System Function in Adults with Anxiety and Related Diseases Karlien Balt1*, Peet Du Toit1, Mark Smith2, and Charl Janse van Rensburg3 1Department of Human Physiology, Faculty of Health Sciences, University of Pretoria, Pretoria, South Africa 2Neurofeedback Services of New York, New York, New York, USA 3South African Medical Research Council, Biostatistics Unit, Pretoria, South Africa Abstract Peripheral body monitoring of autonomic nervous system (ANS) response has been routinely applied during infraslow fluctuation (ISF) neurofeedback training. This study hypothesized that ISF training has a distinct physiological effect on an individual that can be revealed by measuring autonomic function with peripheral biofeedback metrics that included heart rate variability (HRV), muscle tension, skin temperature, skin conductance, heart rate, respiration rate, and blood pressure. Methods. Thirty adults between the ages of 18 and 55, primarily with anxiety, were randomized into two groups: 20 in the experimental group and 9 in the control group. The experimental group completed 10 ISF neurofeedback training sessions while continuous monitoring of ANS changes was applied. The same process was completed for a control group that received one-channel sensorimotor rhythm (SMR) neurofeedback training. Results. Significant changes were seen in the skin conductance (p < .0001), electromyography (p = .01), very low frequency (p = .004), low frequency of HRV (p = .05) and blood pressure (systolic change p = .049) in the experimental group. No significant changes were seen in the control group. Conclusion. The study demonstrated that ISF neurofeedback training impacts the ANS as measured by peripheral biofeedback indicators.

Brainwave Entrainment with Audio 6. Brainwave Entrainment History & Significant Studies 7. Practical Brainwave Entrainment 8. How to Get Started with Brainwave Entrainment 9. Research & Further Reading www.dermaspa.co.za 1. The Science behind Brainwave Entrainment can be explained quickly and easily. To begin, let's start by understanding what "brainwaves" are. We all experience different states of mind each day: states such as sleep, focus, or creativity, for example. Every state of mind has a unique electrical signature that can be detected in the brain. These signatures are known as “brainwaves.” Using specialized equipment, these waves (or frequencies) can be measured and recorded, allowing us to map what brainwaves are present during certain key states of mind. "Brainwave Entrainment" is the process of (typically) using audio and/or visual stimulation to actually change brainwave patterns. By changing your brainwave patterns, you can actually recreate certain states of mind - again, such as sleep, focus or creativity. Usually, this works by listening to a particular brainwave pattern (a specific pulsed frequency, encoded in audio). The brain then follows (entrains) to that pattern, and as a result, changes your state of mind. Quick example: Brainwave readings (with an EEG machine) have shown that brainwaves of 2Hz occur when an individual is asleep. Scientists can create special audio recordings, which contain an encoded 2Hz frequency. While listening to such audio, the brain naturally follows (entrains) toward that 2Hz frequency, lowering its brainwave patterns.

Open-Loop Neurofeedback Audiovisual Stimulation: A Pilot Study of Its Potential for Sleep Induction in Older Adults Abstract This pilot study tested the efficacy of a 30-min audio-visual stimulation (AVS) program for the treatment of chronic insomnia in older adults. Chronic insomnia has been conceptualized as entailing increased cortical high frequency EEG activity at sleep onset and during NREM sleep. We hypothesized that an AVS program gradually descending from 8 to 1 Hz would potentially reduce the excessive cortical activation that is thought to contribute to difficulties with initiating and maintaining sleep.

Forty- six adults who had sight loss significant enough to require the use of a long cane for mobility purposes participated in the study. Participants were between the ages of 18 – 70 years. The study design was a within-subjects, repeated measures design with two levels for the independent variable of the metronome (uncued versus cued) and two levels for the independent variable of tempo (normal walk versus fast walk). Dependent variables of cadence (steps per minute), velocity (meters per minute), and stride length (cadence ÷ (velocity ⁄ 2)) were recorded. Within-subjects repeated measures statistical analyses identified a main effect for the independent variable of the metronome; subsequent analysis revealed that the metronome had a significant effect on the dependent variable of cadence. iii The presence of a rhythmic cue seemed to improve observational gait parameters for many of the study participants.
