Neural Oscillations… What are Brainwave Frequencies? Beyond the Waves of Thought.

Brainwave Frequencies, also known as Neural Oscillations, refer to the electrical patterns produced by the synchronized activity of neurons in the brain.

Brainwave activity is a result of an intricate electrical communication between billions of neurons in the brain. Neurons are specialized cells that transmit information through electrical and chemical signals.

When these neurons fire and communicate with each other they create ‘electrical impulses’ that can be measured by EEG electrodes placed on the scalp.

As the neurons send signals back and forth they produce rhythmic patterns of electrical activity, giving rise to measurable brainwave oscillations. These Neuro-oscillations are the ‘symphony of the brain’ with different groups of neurons working together in synchronized patterns.

These electrical signals are measured in cycles per second or hertz (Hz). Each brainwave frequency is associated with different mental states, cognitive processes and levels of consciousness.

The brainwave patterns can be categorized into different frequency bands based on their oscillation rates, each associated with specific mental states and cognitive processes:

There are Five Primary Brainwave Frequencies:

Beta (13-30 Hz): Beta waves are dominant when we are awake and engaged in active mental and physical activities. They are associated with alertness, focus and problem-solving abilities. Higher beta activity can indicate stress or anxiety.

Alpha (8-12 Hz): Alpha waves are present when we are awake but in a relaxed and calm state, such as during meditation or daydreaming. They are associated with a sense of relaxation, creativity and a state of “mindful alertness.”

Theta (4-7 Hz): Theta waves occur during deep relaxation, meditation and light sleep. They are linked to creativity, intuition and accessing subconscious memories. In this state, the mind is more open to new ideas and insights.

Delta (0.5-4 Hz): Delta waves are the slowest brainwave frequency and are present during deep dreamless sleep. They are associated with restorative and healing processes in the body, as well as memory consolidation.

Gamma (above 30 Hz): Gamma waves are the fastest brainwave frequency and have been linked to higher cognitive functions, information processing, and problem-solving. They are also associated with peak states of consciousness and moments of insight.

Multiple Brainwave Frequencies

Different brainwave frequencies are not isolated, they often occur simultaneously in different parts of the brain, and their patterns can change depending on our mental state and activities. For example, during meditation a person may experience increased alpha and theta activity, indicating a state of relaxation and heightened awareness.

Heinrich Wilhelm Dove, a German physicist, was the first person to discover the phenomenon of binaural beats back in 1839. This auditory illusion laid the groundwork for future exploration into brainwave entrainment. Many natural entrainment techniques (such as chanting, toning, singing bowls etc) have been using this sort of phenomenon for thousands of years.

When exposed to repetitive sensory inputs with particular frequencies, the brain responds by adjusting its own electrical oscillations to match the external stimulus. This phenomenon is known as Frequency Following Response (FFR).

The study of brainwave frequencies, known as electroencephalography (EEG), has significant implications in various fields, including neuroscience, psychology and even entertainment (e.g. brainwave-based music or games).

Within the field of hypnosis recordings often the hypnosis will be coupled with relaxing music and some form of Brainwave Entrainment (e.g. Binaural Beats, Isocronic Tones) because this helps the listener to gently guide into a deeper more meditative state without the actual hypnotist being in the room with them.

All you have to do is press play, lay back and the hypnosis does the rest.
