About Brainwaves

Our brains are 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 equipment such as EEG, measuring electricity levels over areas of the scalp.

The culmination of electrical activity of the brain is commonly called a brainwave pattern, because of its cyclic, wave-like nature.

The electrical activity in the brain will change depending on what the person is doing. Our brains pulse to waveforms with frequency bandwidths that correspond to particular moods, stress levels, and physiological status. As we focus on the complexities of daily life, our brains reflect and emit shorter-frequency alpha or beta brainwaves. A relaxing mood tends to accompany the deeper delta or even the more meditative theta waves. The greater the stress, the higher frequencies tend to get. Just as higher-pitched sounds tend to indicate intensity or urgency, higher frequency waves reflect a mind hustling to keep up with life’s demands.

Researchers have divided the millions of possible brainwave combinations into five general ranges:

Alpha brainwaves are typically the dominant cycle during dream states and light meditation. The alpha waves are oscillations with between 8 and 13 cycles per second. Benefits of Alpha brainwave stimulation.

Beta brainwaves are dominant during normal waking consciousness, and range from 14 to 30 cycles per second. Benefits of Beta brainwave stimulation.

Theta brainwaves are considered to be 4 to 7 cycles per second and dominate during normal sleep and meditation. Benefits of Theta brainwave stimulation.

Delta brainwaves range from less than 1 cycle per second to about 3 cycles per second. These slow brainwaves tend to be dominating during the deepest sleep or deepest meditation states. Benefits of Delta brainwave stimulation.

Gamma brainwaves typically dominate during periods of advanced problem solving or critical thinking. They oscillate at between 30 and 60 cycles per second. Benefits of Gamma brainwave stimulation.

Over the past decade, researchers have discovered the existence of even shorter brainwaves. Ranging from 60 to 200 cycles per second or more, these high-speed brainwaves are referred to as high gamma brainwaves. The high gamma brainwaves are thought to accompany critical thought process and brain functions.

While multiple brainwave types can occur simultaneously, usually one type will predominate. Just as multiple tuning forks will align to a commanding tone, the body will typically tune – harmonically – to the predominant waveform.

What is Brainwave Entrainment?

Brainwave Entrainment refers to the brain’s electrical response to rhythmic sensory stimulation, such as pulses of sound. When the brain is given a stimulus, through the ears, eyes or other senses, it emits an electrical charge in response, called a cortical evoked response. The electrical responses travel through the brain to become what you “see and hear”.

Frequency Following Response can be useful because brainwaves are very much related to a mental state. For example, a 4 Hz brainwaves is associated with sleep, so a 4 Hz sound patter would help produce the sleep state in your brain. The same concept can be applied to nearly all mental states, including concentration, creativity, and many others. It ca even act as a gateway to exotic or extraordinary experiences, such as deep meditation or lucid dreaming type states.

What is Entrainment?

Entrainment is a principle of physics. It is defined as the synchronization of two or more rhythmic cycles. The principles of entrainment are universal, appearing in chemistry, neurology, biology, pharmacology, medicine, astronomy and more.

Our Brainwave Meditations are based on brainwave eintrainment. They gently guide the brain into e certain state to fulfill a specific purpose.
