The brain is made up of billions of brain cells called neurons, which use electricity to communicate with each other. The combination of millions of neurons sending signals at once produces an enormous amount of electrical activity in the brain, which can be detected using sensitive medical equipment (such as an EEG), measuring electricity levels over areas of the scalp.
The combination of electrical activity of the brain is commonly called a Brainwave pattern, because of its cyclic, “wave-like” nature.
Below is a modern EEG recording:
The discovery of brainwaves showed that electrical activity in the brain will change depending on a person’s activity. For example, the brainwaves of a sleeping person are very different than the brainwaves of someone who is awake. Modern science has brought us closer to figuring out what brainwaves represent and what they mean about a person’s health and state of mind.
It is possible to tell a lot about a person simply by observing their brainwave patterns. For example, people who are anxious produce an overabundance of high Beta waves while people with ADD/ADHD tend to produce an overabundance of slower Alpha/Theta brainwaves.
Researchers have found that brainwaves represent ones mental state and can be stimulated to change a person’s mental state, which can in turn can help with a variety of mental issues.
Brainwave Entrainment ~
Brainwave Entrainment is any process that causes one’s brainwave frequencies to synchronize with a periodic stimulus (sound, vibration or light) having a frequency corresponding to the intended brain-state (for example, to induce a trance, dreams, sleep or relaxation.) It is also called the Flicker-response because of how staring at a campfire or the flickering of a burning candle can lull you into a state of calmness and serenity. Audios from Tonal Meditation use a unique combination of powerful brainwave entrainment technologies.
