Usually, there is a need for a second person to actuate the bowl. Addressing these limitations, we built an electronic device, named eBowl, which can mimic the acoustics of Tibetan bowls, and beyond that, can produce a wide range of other sounds. 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.

  • Large Scale Sound Installation Design: Psychoacoustic Stimulation
    LARGE SCALE SOUND INSTALLATION DESIGN: PSYCHOACOUSTIC STIMULATION An Interactive Qualifying Project Report submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science by Taylor H. 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 .................................................................................................................

  • Brainwave Entrainment a Guide on All You Need to Know
    Brainwave Entrainment A guide on all you need to know 1. The Science behind Brainwave Entrainment 2. What Are Brainwaves 3. Why Are Brainwaves Important 4. What Is Brainwave Entrainment 5. 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.

The efficacy was compared in a pre- and post analysis over a treatment period of 3 month with a control group and a group of patients with an EEG- based neurofeedback therapy. The number of impulsivity errors in a stop-signal paradigm at several distinct times during and after the therapy was used as a quality marker. The main feature of this method uses real-time-EEG data derived pa- rameters for a controlled manipulation of EEG patterns with persistently strong audio-visual stimuli. It is based upon a direct feedback of changes in short-term coherences in the context of central nervous stimulus processing to control the stimulating frequency.

  • Brain.Fm's Science
    Brain.fm’s Science FAQ Compiled by Adam Hewett (co-founder of Brain.fm) and Dr. Benjamin Morillon (Aix-Marseille Université) Does Brain.fm have any peer- reviewed papers published? Brain.fm is currently in the process of scientifically validating its concepts, but no study is currently published. In collaboration with Dr. Psyche Loui from Wesleyan University (USA) and Dr. Benjamin Morillon from Aix-Marseille University (France), Brain.fm is currently investigating the impact of its music at both the behavioral and neurophysiological level – thanks to Electroencephalography (EEG) and functional MRI (fMRI). Some pilot data can be found at: www.brain.fm What is the definition of ‘Dynamic Attending Theory’ (DAT)? The dynamic attending theory was developed by Dr. Mari Riess Jones1,2. The idea is that during perception attention is modulated dynamically to optimize sensory processing at expected points in time. Crucially, this framework capitalizes on the fact that many stimuli and actions are rhythmically organized (e.g. speech, music, walking, among others). By extracting such temporal regularities, the brain is able to predict the occurrence of subsequent events of interest and optimize their processing3. In other words, attending itself is an oscillatory process that entrains to environmental rhythms, thus improving perceptual discriminative performance4. How exactly does DAT work from a neurological perspective? Neuronal (or oscillatory, brainwave) entrainment is the likely physiological substrate, ​ ​ mechanism, by which DAT operates. Neuronal oscillations correspond to regular variations of electric activity in the brain. They regulate the occurrence of action potentials, hence the communication between neurons. Neuronal oscillations have an important role in brain operations to the extent that understanding of neuronal oscillation ‘rhythms’ now seems to be 5 essential to our understanding of brain function .​ ​ When a temporal regularity is present in the environment, neuronal oscillations can synchronize (i.e.

    FEATURES The Science of Energy Therapies and Contemplative Practice A Conceptual Review and the Application of Zero Balancing ■ Sallie Stoltz Denner, MSN, CCIT, CZB, CRNA The topic of energy therapies is prompted by the increasing attention of healthcare practitioners and consumers to Eastern philosophies and ancient healing practices. This article includes a conceptual framework of quantum physics principles providing the basis of interpretation of energetic phenomena, along with the exploration of theoretical concepts involving energy as a communicational network. An overview of the contemplative tradition of meditation indicates its necessity as a requisite element of energy therapies, the practice combining a knowledge base of the core scientific precepts with the experience of restorative strategies. The relevance of energy therapies as a path to self-transcendence along with the application of a specific touch technique, Zero Balancing, is highlighted.
