Brain Waves: Delta Theta Alpha And Gamma
Written and verified bythe psychologist.
15 November, 2021
There are 5 kinds of brain waves and they work almost like musical notes. Some are low frequencies, others are high frequencies. Together they have the power to create harmony. Your thoughts, emotions and sensations in perfect balance, centered and open to everything around you.
Have you ever heard someone say something like, I want to train my Alpha brain waves to be more relaxed and get more inner peace? In fact, people have even been talking about bio-feedback machines that can stimulate certain brain waves to get us into certain states of consciousness. Well, we should step carefully here
The eye grasps The brain gives things shape
When it comes to our brain waves, the key to authentic health and happiness lies in allowing each of them to work in their way, at their frequency and at their optimum levels. We should also remember that they arent static. Rather, they change as we get older. So, the point isnt to get obsessed with improving our Beta waves for better focus or our Gamma waves to get into a spiritual state.
The truth is that no one type of brain wave is better or more special than another. They are all important, because theyre all the result of the electrical activity of our neurons and mental states.
Other Types Of Brain Waves
In addition to alpha brain waves, four other types of brain waves can be found within the brains electrical activity.
Five different types of brain waves include:
- Delta brain waves are the slowest brain waves. They are present during a deep state of unconsciousness. They move between 0.5 and 4 Hz per second.
- The theta brain waves are slightly faster and present themselves during light sleep or deep relaxation. They move at a pace of 4 and 8 Hz.
- In the middle of these brain waves falls alpha brain waves. They move somewhere between 8 and 12 Hz which places them at a medium pace within the brain wave patterns.
- The beta brain waves occur during a conscious or awake state. This is when a person is attentive and alert. You will find that they are faster moving than the other ones, moving between 12 and 30 Hz.
- Gamma brain waves are the fastest brain waves. They move between 25 and 100 Hz at any given moment. They are present during periods of high brain activity, such as learning, processing information, and problem-solving.
How Alpha Waves Compare To Other Brain Wave Patterns
Like ocean waves, brain waves are in a constant state of motion, and they travel at different speeds. The speed of a brain wave is called its frequency, and scientists measure it in hertz . Alpha brain waves have a moderate frequency of 8 to 12 Hz. Here’s how that compares to the other four brain waves:
- Delta waves are the slowest type, traveling at 0.5 to 4 Hz. Your body produces these when you are in a state of dreamless sleep
- Theta waves are the second slowest type, traveling at speeds of 4 to 8 Hz. These waves correspond to light sleep and dream sleep
- Beta waves are the second-fastest type, traveling at 12 to 35 Hz speeds. These waves dominate when you’re doing everyday tasks and making simple decisions
- Gamma waves are the fastest type, traveling at speeds of over 35 Hz. These waves show up during complex tasks like analyzing information and learning new things

Its All About The Rhythm
Alpha brain waves are quite rhythmical.
They make you feel content, relaxed, and happy.
When youre experiencing them, you are able to tune out the world thats around you and focus on your own happiness.
Your own wellbeing. Your own relaxation.
Thats what makes alpha waves such a great thing to experience!
The brain needs time to be able to relax.
It must have it.
If you are not taking time out of the day to let the alpha waves work their magic, youre going to start feeling worn down.
Youre going to feel tired.
When you feel tired, you get even fewer alpha brain waves.
Its a vicious cycle that keeps repeating itself over and over again.
Its not about taking time out for yourself when you feel stressed out.
Its about always making sure that you take some time for yourself.
When you are in prayer or meditation, you are experiencing alpha brain waves.
When you close your eyes and listen to some of your favorite music, you are working on your alpha waves.
You can also entrain your brain to hear certain tones and produce alpha waves.
The real question, however, is why.
Why should you attempt to increase the output of alpha brain waves in your mind?
The answer is simple. Because you can experience these benefits:
- lower pulse rate,
Supplements For Mental Clarity And An Optimal State Of Mind
Dietary supplements may also provide a way to support an optimal state of mind. Some supplements to consider include:
- Cocoa bean extract: Contains theobroma, which may increase mental alertness by increasing blood flow to oxygenate the brain
- Caffeine: May enhance mental clarity by stimulating the central nervous system
- Ashwagandha: Thought to act as an adaptogen to protect the mind and body from stress
- GABA: Believed to supplement levels of a critical neurotransmitter that the body needs for relaxation and stress management
You can take brain health supplements individually or choose a combination product like Xeed Balance Daily Chill for mood support and stress relief or Xeed Focus Daily Clarity to support mental clarity and cognitive function.

The Legacy Of Alpha Brain Waves And Modern Neurofeedback Devices
Half a century after Kamiyas experiments, EEG-aided meditation is once again in vogue. Yet, that is not to say that modern devices are equivalent to those once used by technologically-inclined hippies. For starters, early alpha monitors often consisted of only one or two electrodes, severely limiting accuracy and reliability. Modern products, by contrast, usually have at least 6 electrodes, and often many more than that.
Moreover, whereas first-generation devices responded only to the presence or absence of alpha, modern products may apply targeted algorithms to compare brainwave frequencies recorded from numerous brain regions. And, as EEG data processing improves, feedback protocols will likely prioritize signal features more complex than broad categories like alpha or theta.

While alpha feedback remains an active area of study, researchers are now investigating its application in more diverse contexts, such as for the management of ADHD or PTSD. . In these cases, the application in question will dictate the EEG electrode placement and best practices may call for the recognition of inter- and intra-subject variability, a distinctly modern facet of neurofeedback, which has been discussed previously on this blog.

What Are Brain Waves
Your brain has electricity running through it all the time. Electrical signals work with chemicals to create your experience of the world.
You can measure your brains electrical activity with an electroencephalogram . If you do, youll notice waves of electricity that travel across your brain in a regular, repeating pattern. These are brain waves, and they have a huge impact on how you think and feel. There are a few different types of brainwaves, each with different effects:
- Beta waves mediate attention and sometimes produce anxiety.
- Theta waves rise during drowsiness and daydreaming. They can also increase your sense of connectedness with people around you.
- Delta waves increase during restorative sleep.
Then there are alpha waves. Alpha waves give you a feeling of deep calm, coupled with productivity, creativity, and effortless focus. Lets take a closer look at them.
Impact Of Alpha Waves
Interest in the use of alpha waves grew after the development of biofeedback, a technique that involves using feedback from a tool that measures brain activity to learn how to consciously create alpha waves. Research has shown that alpha waves may have a number of positive benefits, which might include the following:

Alpha Brain Waves And The Counterculture
Adrian and Matthews concluded that alpha dominates when the brain lacks visual stimulation. Taking this finding a step further, Kamiya showed that the waves fade when subjects merely imagine visual scenes. He explains:
All those who had taken part in the experiment described various kinds of visual imagery or seeing with the minds eye as occurring in the non-alpha state. The alpha state commonly was reported as not thinking, letting the mind wander, or feeling the heart beat.
Put another way, Kamiya found that subjects were able to increase alpha by closing their eyes and clearing their mindsa state conspicuously similar to meditation. This similarity was not lost on Kamiya, who happened to publish his research at the same time that Eastern meditative rituals were gaining popularity among the American counterculture.
Working out of Northern California in the late 1960s, Kamiyas lab was located at the heart of the hippie movement and the human potential movement. Within this cultural milieu, alpha quickly acquired a transcendental, spiritual connotationa connotation that Kamiya himself embraced.
This rhythm, which is observed occasionally in sleep, and during yoga and Zen meditation, is known as the alpha rhythm. Because it has been recorded in people while they were experiencing pleasurable relaxation or meditation states…a cult has been growing up around the alpha state.
At The End What Nootropic Should I Buy
Utilizing nootropics toboost your mental efficiencymay look like an excellent idea. But before you begin popping pills, you need to understand that different nootropics work in different ways. Some boost memory, while others reduce anxiety. Some are natural, while others are synthesized in a lab.
And some of these natural supplements are even proven to be reliable.Once upon a time, individuals relied on their own natural abilities to remain sharp and focused. Alas, in the modern-day world, these capabilities have actually been sorely disregarded, that makes it hard to focus at work, keep in mind essential information, and stay on subject throughout conferences.
Whats an ambitious young professional to do? If youre a brainiac in need of an increase, your best bet is to try a nootropic, or wise drug, that can help you work harder, study longer, and, eventually, improve your efficiency.

Close Your Eyes & Visualize
In addition to providing a cool rhyme, the recommendation to close your eyes & visualize can actually help to produce alpha brain waves. This puts you into the ideal alpha brain wave state: processing very small amounts of information without needing to focus too intently. This may also be called daydreaming.
General Neurophysiology Of Listening To Music
Scientific studies investigating the effect of music on the brains of healthy people often use Sonata in D Major for Two Pianos K448 by Wolfgang Amadeus Mozart. In fact, this piece has inspired Campbells The Mozart Effect. According to current literature, this sonata causes a significant increase in relative alpha band power, as well as in a median frequency of background alpha rhythm in young adults and healthy elderly people. Interestingly, during this study no significant changes were observed while listening to Beethovens Für Elise .
Sonata K448 is also known to improve spatial performance. A few brainwave patterns correlating to this improvement are lowered theta power in the left temporal area increased beta range in the left temporal, the left frontal, and the right temporal regions increased alpha 1 power left temporally. Again, these patterns have been found to emerge while listening to this particular piece .
The effect of music, however, might not be dependent on a specific piece. According to scientists, music that is personally liked by the subjects turns out to enhance EEG power spectra globally and also across bandwidths. The effect is best seen in beta and alpha frequencies in the right frontal and temporal regions. Disliked music, musical improvisations, or white noise do not seem to have the same impact, although white noise also produces similar responses on the left hemisphere .

Magnetoencephalography In Response To Change In T1
In MEG studies, weak magnetic fields produced by electric currents flowing in neurons are measured with multiple channel SQUID gradiometers, which enable the study of many interesting properties of the working human brain. MEG accurately detects superficial tangential currents, whereas EEG is sensitive to both radial and tangential current sources and also reflects activity in the deepest parts of the brain. Only currents that have a component tangential to the surface of a spherically symmetric conductor produce a sufficiently strong magnetic field outside of the brain radial sources are thus externally silent. Therefore MEG measures mainly activity from the fissures of the cortex, which often simplifies interpretation of the data.
Fortunately, all the primary sensory areas of the brainauditory, somatosensory, and visualare located within fissures. The advantages of MEG over EEG result mainly from the fact that, although the skull and other extracerebral tissues substantially alter current flow, they are practically transparent to magnetic fields. Thus magnetic patterns outside the head are less distorted than the electrical potentials on the scalp. Furthermore, magnetic recording is reference free, whereas electric brain maps depend on the location of the reference electrode.
Measurements of MEG responses were performed in a magnetically shielded room using a 122-channel whole-head neuromagnetometer, as shown in Photo 6.1. .11

What Is The Function Of The Various Brainwaves
Ned Herrmann is an educator who has developed models of brain activity and integrated them into teaching and management training. Before founding the Ned Herrmann Group in 1980, he headed management education at General Electric, where he developed many of his ideas. Here is his explanation.
It is well known that the brain is an electrochemical organ researchers have speculated that a fully functioning brain can generate as much as 10 watts of electrical power. Other more conservative investigators calculate that if all 10 billion interconnected nerve cells discharged at one time that a single electrode placed on the human scalp would record something like five millionths to 50 millionths of a volt. If you had enough scalps hooked up you might be able to light a flashlight bulb.
The next brainwave category in order of frequency is alpha. Where beta represented arousal, alpha represents non-arousal. Alpha brainwaves are slower, and higher in amplitude. Their frequency ranges from 9 to 14 cycles per second. A person who has completed a task and sits down to rest is often in an alpha state. A person who takes time out to reflect or meditate is usually in an alpha state. A person who takes a break from a conference and walks in the garden is often in an alpha state.

What Are Brain Wave Patterns
Electrical impulses are what power the mind. Both the conscious and unconscious activities of the mind occur when neurons in the brain transmit electrical signals. Doctors and researchers can examine the brain’s electrical activity using a test called an electroencephalogram test. The test represents various types of electric activity as wave patterns. As a result, we refer to the electrical activity in the brain as brain waves or brain wave patterns.
