Brain frequencies

Brain frequencies can be measured with sensors placed on the scalp - then displayed as brain waves, graphs, or data.

Brain frequencies can be displayed as they are generated by the brain, in real time - and can also be recorded for further analysis.

Brain frequencies are waves that vary in amplitude (height) and frequency (how often they occur). The number of waves per second is refered to as hertz or Hz.

Brain frequencies can reveal a surprising amount of information as to the physical and mental state of the person being measured. A range of brain frequencies are generated in each of the brain hemispheres.

Commonly recognized ranges of brain frequencies

Beta brain frequencies

These waves are 14 Hz to 30 Hz (and higher according to some) - they are the dominant brain frequencies when our eyes are open, when we are listening, thinking, analyzing, problem solving, judgeing, making decisions, and processing information about the world around us.

Alpha brain frequencies

These waves are 8 to 13.9 Hz and are the dominant brain frequencies when we are relaxed. Healthy alpha production promotes mental resourcefulness, assists in the ability to mentally coordinate, enhances overall sense of relaxation. Most people feel at ease and calm. Alpha is the bridge between the conscious and the subconscious.

Theta brain frequencies

These waves are 4 to 7.9 Hz and are connected with creativity, intuition, daydreaming, and fantasizing, storing memories, emotions, and sensations. Theta waves are strong during internal focus, meditation, prayer, and spiritual awareness.

Delta brain frequencies

These waves are 0.1 to 3.9 Hz and occur in deep sleep, in some abnormal processes, and during experiences of empathy. Delta waves are tied to our ability to integrate and let go.

Other brain frequencies

There are several lessor acknowledged ranges of brain frequencies that occur above 30 Hz named gamma, hypergamma, lambda, and epsilon.

Diagrams of brain frequencies
It would be interesting to see diagrams or pictures of brain frequencies being generated in different emotional states.

What does someone's brain frequencies look like when they're mad, or happy, or deeply in love, or you get the idea.

Manifesting with brain frequencies
Angela S
I have read that some of the upper brain frequencies - the kinds that Buddhist monks can control - are what causes "things to manifest". I'd like to see more on your site about this.
