Biofeedback enhancement: In 1981, researcher Arturo Manns discovered that 15 minutes of stimulation with isochronic tones enhanced biofeedback protocols for bruxism (grinding of teeth). They did this by increasing muscle relaxation superior than standalone biofeedback. Brainwave entrainment is different from biofeedback in that it does not allow the person to consciously control their brainwave state.

Anabel debuts in the Emerald chapter. She is one of the seven Trainers hired by Scott to be a Frontier Brain at the Battle Frontier. Anabel is first seen watching the Battle Frontier's opening ceremony. The ceremony is interrupted by Emerald, who announces that he wishes to conquer the Battle Frontier. The press mistakenly report the incident as allowing an ordinary Trainer to take part in the Battle Frontier before it officially opens a week later. The Frontier Brains decide to use this assumption as free publicity and allow Emerald to challenge the Battle Frontier under the condition that he completes it before it officially opens.
There are differences between high (over 18 hertz), mid (15 to 18 hertz), and low range beta states (12 to 15 hertz). Low beta states are more relaxed while still being focused, making this a good range for many daily work related tasks like balancing a checkbook, making a shopping list, or driving to a new place. However, people with attention deficit disorder lack the mental focus for doing these types of activities, and studies have found people with ADD are often low in this range of beta brainwaves.
The pitch frequency measures and describes what a beat sounds like, i.e. does the isochronic beat have a deeper bass sound, or is it high pitched and sharper sounding? The beat waveform frequency describes how many times the beat is repeating per second, i.e. how fast it is beating. You don’t really need to concern yourself about the pitch frequency, as that doesn’t have a direct influence on brainwave entrainment and doesn’t play a part on the measurement on an EEG. I only mentioned it because you were referring to humans not being able to hear below 20Hz. I change the pitch frequency just to suit the mood of the track. For tracks that are to be relaxing, for meditation or sleep, I tend to use a lower pitch frequency so it sounds deeper and more relaxing and I never have that lower than 100Hz. For an energizing, high focus track I might use a more higher pitched 200Hz isochronic tone, because that is sharper sounding and less likely to make you feel sleepy. That’s all you really need to know about the pitch frequency.
Gamma brainwave states are the most rapid in frequency. Gamma has long been considered the brainwave that is able to link and process information from all parts of the brain. It is the frequency that brings with it the ability to process large amounts of information in relatively small amounts of time. Think of generating more Gamma activity as getting a processor upgrade for your brain.
As strange as it may sound, vocal toning is a special technique that reduces the stress hormones adrenaline and cortisol. Try sneaking off to a quiet place to spend a few minutes toning before a meeting with your boss and see how much more relaxed and focused you feel. It works by exercising the tiny muscles of the inner ear that help you detect the higher frequencies of human speech that impart emotion and tell you what someone is really trying to say. Not only will you feel more relaxed in that meeting, you’ll also be better able to understand what he’s trying to communicate.
Binaural beats were the first method discovered for brainwave entrainment and works by delivering tones of different audible frequencies to the two ears with the difference in frequency between the two tones being the frequency of entrainment. The difference in frequency between the two tones must be less than 30 hertz, and this resulting frequency is called a beat or the target frequency, and it is processed in a brain region called the olivary body. When listening to such tones with stereo headphones, the two hemispheres of the brain become synchronized at the target frequency.

Maybe a favorite popular song, a certain piece of Classical music, a raucous dance beat, the pulse of Reggae, Indian, or African drums, or the chanting of Gregorian or Tibetan monks, but you probably know how the sound of music, drumming, or chanting is capable of transporting you into an altered and joyous state of mind and uplifting your spirits.


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).
The stress of the mind control eventually causes Anabel to pass out, forcing Guile to use her as a hostage in order to force Noland to give him the Jirachi Report, which contains the secrets of how to make Jirachi grant his wish. When Noland is unsure about what to do, Guile attacks him and takes the report by force. Now knowing Jirachi's secret, Guile has Jirachi create a gigantic Kyogre made of seawater and uses it to flood the entire Battle Frontier. Anabel is taken to safety by Latios and later awakens to help the Frontier Brains fight off Guile's rental Pokémon while Emerald and the other Pokédex holders fight Guile. Eventually, Emerald and the Pokédex holders manage to defeat Guile and destroy the gigantic Kyogre monster. The day after, an injured Anabel and the other Frontier Brains congratulate Emerald for the hard work he put into saving everyone. Anabel then awards Emerald the Ability Symbol for his skills in traversing the Battle Tower.

“Whereas my regular meditation practice gives slow results, I can get into a state of deep relaxation very quickly using the Brain Salon. This is so useful, especially when I need to make a presentation or deliver a pitch. The series helps me de-condition myself from my mind's negative patterns - patterns of stress, anxiety and fear - and instead installs new patterns which help me achieve my goals and end self-sabotage. Love it. Keep up the good work.”
