Role of Beta Waves in Having a Healthy Brain
- Beta Power (and Alpha Power) is a good indicator of how much activity and metabolism is occurring in your brain.
- Beta tends to become less rhythmic when you are concentrating on something that is mentally challenging. ...
- Some neurofeedback seeks to increase Beta in the 12-18 Hz range or to reduce the Theta / Beta ratio to aid in attention.
What do beta waves indicate?
Beta waves are present when we are in a state of mental or intellectual activity and outward focus, like when we are thinking, problem-solving, processing information or feeling anxious. However, people with excessively high Beta activity may have conditions such as anxiety, obsessive-compulsive disorder, irritability, agitation, insomnia, bipolar tendencies, and substance abuse.
What is the frequency of beta waves?
When the brain is aroused and actively engaged in mental activities, it generates beta waves. These beta waves are of relatively low amplitude, and are the fastest of the four different brainwaves. The frequency of beta waves ranges from 15 to 40 cycles a second. Beta waves are characteristics of a strongly engaged mind.
What does beta wave mean?
Beta waves are high-frequency, low-amplitude brain waves that are commonly observed in an awaken state. They are involved in conscious thought and logical thinking, and tend to have a stimulating effect. Having the right amount of beta waves allows us to focus.
Is beta a wave or particle?
These particles are known as the beta particles. Beta particles are high-energy, high-speed electrons or positrons emitted by certain fission fragments or by certain primordial radioactive nuclei such as potassium-40. The beta particles are a form of ionizing radiation also known as beta rays.
What does it mean to have high beta waves?
High beta waves (18–40 Hz): known as “beta three” waves and associated with significant stress, anxiety, paranoia, high energy, and high arousal.
What does beta waves mean in psychology?
Beta waves are characteristics of a strongly engaged mind. A person in active conversation would be in beta. A debater would be in high beta. A person making a speech, or a teacher, or a talk show host would all be in beta when they are engaged in their work. The next brainwave category in order of frequency is alpha.
What are beta waves good for?
If we close our eyes and begin picturing something peaceful, there is an increase in alpha brainwaves. Beta brainwaves (13 – 38 Hz) are small, faster brainwaves associated with a state of mental, intellectual activity and outwardly focused concentration. This is basically state of alertness.
What causes low beta waves?
Low-amplitude beta waves with multiple and varying frequencies are often associated with active, busy or anxious thinking and active concentration.
What causes excessive beta activity?
Excessive Beta activity on quantitative analysis can relate to symptoms of brain over arousal such as anxiety, obsessiveness, sleep difficulties, hyperactivity, etc. Deficient Beta activity on quantitative analysis can relate to symptoms of brain under aroused such as difficulty concentrating, problem solving, etc.
What does it mean to have slow brain waves?
Focal slow wave activity on the EEG is indicative of focal cerebral pathology of the underlying brain region. Slowing may be intermittent or persistent, with more persistent or consistently slower activity generally indicating more severe underlying focal cerebral dysfunction.
What causes excessive beta activity on EEG?
Greater than usual theta activity may accompany such beta excess (Blume et al., 2002). Central nervous system stimulants such as cocaine, amphetamines, and methylphenidate as well as tricyclic antidepressants may evoke greater beta activity at low voltage (G. Bauer and R.
What increases beta brain waves?
In my opinion, the easiest way to increase beta waves is listening to beta binaural beats. Beta binaural beats are nothing more than a track with two beats, where one is played on each ear at different frequencies. For example, the right ear may have a tone tuned to 220Hz and the left one to 200Hz.
Which frequency is best for brain?
6 Hz beat enhances all area of the brain within 10 minutes. 8 Hz and 25 Hz beats have no clearly responses while 40 Hz beat enhances the responses in frontal lobe. These brain responses can be used for brain modulation application to induce the brain activity in further studies.
What brain wave is anxiety?
Beta waves are associated with alertness, but when maintained too long lead to feelings of fear and anxiety. So, if you are stressed and anxious, learning how to increase alpha waves while reducing beta wave activity might be your goal.
What is an abnormal EEG?
An abnormal EEG means that there is a problem in an area of brain activity. This can offer a clue in diagnosing various neurological conditions. Read 10 Conditions Diagnosed With an EEG to learn more. EEG testing is one part of making a diagnosis.

In my opinion, the easiest way to increase beta waves is listening to beta binaural beats. Beta binaural beats are nothing more than a track with two beats, where one is played on each ear at different frequencies. For example, the right ear may have a tone tuned to 220Hz and the left one to 200Hz.
What brain waves are associated with anxiety?
Beta waves are associated with alertness, but when maintained too long lead to feelings of fear and anxiety. So, if you are stressed and anxious, learning how to increase alpha waves while reducing beta wave activity might be your goal.
What does alpha waves mean in psychology?
Alpha waves, which measure between 8 and 12 Hz, occur when people feel relaxed and when the brain is in an idle state without concentrating on anything. Beta waves, which measure between 12 and 30 Hz, are the waves that occur during most conscious, waking states.
What is the beta wave?
Beta waves are often considered indicative of inhibitory cortical transmission mediated by gamma aminobutyric acid (GABA), the principal inhibitory neurotransmitter of the mammalian nervous system. Benzodiazepines, drugs that modulate GABA A receptors, induce beta waves in EEG recordings from humans and rats.
What is the frequency of a beta wave?
Beta wave, or Beta rhythm, is a neural oscillation (brainwave) in the brain with a frequency range of between 12.5 and 30 Hz (12.5 to 30 cycles per second ). Beta waves can be split into three sections: Low Beta Waves (12.5–16 Hz, "Beta 1 power"); Beta Waves (16.5–20 Hz, "Beta 2 power"); and High Beta Waves (20.5–28 Hz, "Beta 3 power").
What is the difference between high beta and low beta?
In association with unexpected gains, the high beta component is more profound when receiving an unexpected outcome , with a low probability. However the low beta component is said to be related to the omission of gains, when gains are expected.
What is low amplitude beta wave?
Low-amplitude beta waves with multiple and varying frequencies are often associated with active, busy or anxious thinking and active concentration. Over the motor cortex, beta waves are associated with the muscle contractions that happen in isotonic movements and are suppressed prior to and during movement changes.
Who invented beta waves?
Beta waves were discovered and named by the German psychiatrist Hans Berger, who invented electroencephalography (EEG) in 1924, as a method of recording electrical brain activity from the human scalp.
Which wave is the larger amplitude, slower frequency waves that appeared over the posterior scalp when the subject's answer?
Berger termed the larger amplitude, slower frequency waves that appeared over the posterior scalp when the subject's eye were closed alpha waves. The smaller amplitude, faster frequency waves that replaced alpha waves when the subject opened his or her eyes were then termed beta waves.
Where does beta wave activity occur?
In one type, known as Rolandic beta rhythms, beta activity occurs in the sensory-motor area of the brain with a frequency of 20 Hz. This type of beta wave activity appears as a person prepares to move their body. It then disappears briefly as the person makes the action, returning shortly afterward.
What are Beta Brainwaves?
Beta brain waves were the second type of distinct electrical activity observed in 1929 by Hans Berger, the discoverer of brain waves. Berger’s first discovery was alpha waves, and he named them after the first letter of the Greek alphabet.
How to stimulate beta brain wave?
You can do this by listening to binaural beats designed to induce brain wave frequencies in the range of 13 to 30 Hz.
What is low beta?
Low beta brainwaves are those between 12.5 to 21 Hz, overlapping slightly at the lowest range with alpha frequencies. Low beta is likely to be present as your mind moves from an alpha state during meditation or daydreaming toward thinking about something specific or engaging in an activity.
What are theta, delta, and gamma waves?
However, before long, he and other researchers determined that theta, delta, and gamma waves each corresponded to different states of awareness. Each brain wave type has a different function and outcome for our state of mind and level of consciousness.
Why is beta wave frequency bad?
When our brain stays too long in beta waves, the hemispheres become less synchronized. An excess of beta wave frequency can result in: Anxiety. Panic attacks.
What frequencies are good for reducing beta waves?
For most of us, listening to binaural beats in the alpha, theta, or delta fre quencies ranges is a safe and straightforward way of reducing excess beta waves. For some people, inducing beta waves with binaural beats or other techniques may help in achieving better mental focus and concentration.
What are beta waves?
Beta waves are prominent during states of concentration and problem solving. Beta waves are common in the EEG’s of most waking adults but may also be present during drowsiness. Beta waves tend to be more visible in the EEG when the patients eyes are open.
Why is beta less rhythmic?
Beta tends to become less rhythmic when you are concentrating on something that is mentally challenging. This correlates with increased blood oxygenation and metabolism in the brain. Some neurofeedback seeks to increase Beta in the 12-18 Hz range or to reduce the Theta / Beta ratio to aid in attention.
What is beta asymmetries?
Beta asymmetries are usually pathological over the side with reduced amplitude, especially if the asymmetry is greater than 50%. However, other frequency asymmetries should be considered before determining abnormality (is there also reduced Alpha / increased Theta, etc.). Interhemispheric Beta Asymmetries can be due to remote infarcts ...
Why are beta asymmetries interhemispheric?
Interhemispheric Beta Asymmetries can be due to remote infarcts or subdural collections (bruises, swelling, etc.).

What is the meaning of sensory-motor beta?
It becomes less rhythmic with motor action or motor planning and more rhythmic following motor actions. Sensory-motor Beta reflects the resting and resetting of the motor system following information processing. The more frequently Beta rhythms synchronize (the faster the rhythm) the more excitable the cortex (surface of the brain).
Where is the frontal beta located?
Frontal Beta is localized to front of the head and it is composed of irregular rhythms generally less than 20 Hz.
Why do we have beta waves?
With too much beta, we can run into problems such as stressing ourselves out. There is a time and place for each one of the major brain waves. Beta waves are most beneficial while we are working and need to think critically or problem solve. The purpose of beta waves is to increase our level of cortical arousal.
What is the beta brain wave?
Most people tend to think of beta brain waves as being involved in critical thinking. They are associated with states of alertness, concentration, energy, and focus. When you wake up, your brain experiences a boost in beta activity. For most people, their dominant brain wave throughout the day is somewhere within the beta range.
Why does beta activity increase?
Stress: Anytime you experience stress of any sort, your beta activity is going to increase. Individuals in high pressure jobs or occupations that require long hours and high levels of performance can keep people stressed. This is because stress will cause your brain to produce extra beta activity.
What are the different types of brain waves?
Beta Brain Waves: 12 Hz to 40 Hz 1 Low Beta Waves (12 Hz – 15 Hz): These are commonly referred to as “Beta 1” ( SMR brain waves) waves and are in the lower cycles per second. The lower range of Beta activity is often associated mostly with quiet, focused, introverted concentration. 2 Mid-Range Beta Waves (15 Hz – 20 Hz): These are commonly referred to as “Beta 2” waves and are faster in regards to oscillations per second. Mid-range Beta activity is associated with increases in energy, anxiety, and performance. 3 High Beta Waves (18 Hz – 40 Hz): These may be referred to as “Beta 3” waves and are the fastest oscillating brain waves until beta transitions to gamma waves. The high-range Beta is associated with significant stress, anxiety, paranoia, high energy, and high arousal.
What is a low beta wave?
Low Beta Waves (12 Hz – 15 Hz): These are commonly referred to as “Beta 1” ( SMR brain waves) waves and are in the lower cycles per second. The lower range of Beta activity is often associated mostly with quiet, focused, introverted concentration.
Why do people become addicted to beta?
They become addicted to things that help them either calm down these brain waves or fuel further excitement. For example, someone who is stressed out a lot may turn to alcohol to temporarily suppress this activity. Other individuals may turn to gambling because they are addicted to the excitement.
Why are beta waves beneficial?
There is a time and place for each one of the major brain waves. Beta waves are most beneficial while we are working and need to think critically or problem solve. The purpose of beta waves is to increase our level of cortical arousal. Pros: Alertness, concentration, energy, focus, IQ, performance.
What are the characteristics of brain waves?
Certain frequencies of brain waves are inhibitory, whilst others are excitatory. This means that the stimulation of certain wave bands may be responsible for characteristics associated with over-arousal (e.g. fidgeting, hyperactivity and feelings of agitation), whilst others lead to features of under-arousal (e.g. poor concentration, spaciness, and day-dreaming)
What is theta wave?
Theta waves (4-8 Hz) are particularly involved in day-dreaming and sleep. Cortical theta is observed frequently in young children, but in older children and adults, it tends to appear during meditative, drowsy, or sleeping states (but not during the deepest stages of sleep). When we are awake, excess theta levels can result in feeling scattered or day-dreamy, and is commonly reported in ADHD. Too much theta in the left hemisphere is thought to result in lack of organisation, whereas too much theta on the right results in impulsivity. Theta in people with attention disorders is often seen more towards the front of the brain.
What is delta in the brain?
Because delta is active within brain networks that connect the cortex and insula with the hypothalamus and the brainstem, delta is closely involved with the physiological interface between the brain and the body.
How do gamma and theta work together?
Gamma and theta work together to recruit neurons which stimulate local cell column activity. As such, it is associated with cortical processing related to cognitive functions, and is also potentially related to meditative states, although research on this relationship is vague.
What are the different brain waves?
When slower brain waves are dominant we can feel sluggish, inattentive and scattered, and can feel depressed or develop insomnia. When higher frequencies abound, we are engaged in critical thinking, hyper-alertness or anxiety, but can also result in nightmares, hyper-vigilance and impulsive behaviour.
Which part of the brain is involved in regulating the emotional state from restless anxiety to focused relaxation?
When anxiety is medicated, the signal is restored. This suggests that the anterior cingulate cortex is involved in regulating the emotional state from restless anxiety to focused relaxation. Hippocampal Theta: Has been found in the posterior cingulate, entorhinal cortex, hypothalamus and amygdala.
Why does alpha decrease during sleep?
Alpha diminishes during sleep onset, while focusing on tasks, and is also a normal consequence of ageing. When alpha slows and theta increases in frequency , it is often an indicator of pathologically slowed high-amplitude alpha, which is associated with Parkinson’s disease and cognitive decline.
What Are Beta Brainwaves?
Beta brain waves mainly occur, when we are awake and doing a task that involves active thinking. For example, students in school or university will display many on an EEG (an EEG is an instrument that is used to measure brain waves), as long as they are paying attention. Also, people in a job will mostly show many beta brain waves. As a counter example, people watching TV are in a rather relaxed state and will not have that many beta brain waves.
How to increase beta waves?
In my opinion, the easiest way to increase beta waves is listening to beta binaural beats. Beta binaural beats are nothing more than a track with two beats, where one is played on each ear at different frequencies. For example, the right ear may have a tone tuned to 220Hz and the left one to 200Hz. The difference is 20Hz, which will induce the brain to produce this specific beta wave. Many YouTubers provide these tracks for free. Sometimes, these tracks have natural sounds in the background, since for some people it is easier to focus with these sounds.
Why do we listen to beta binaural beats?
When you cannot really focus on something for any reason it is advisable to listen to beta binaural beats in order to stimulate your brain to go into concentration mode. Motivator: It is said that increasing beta waves in students, who are demotivated with studying, can be a true motivation boost.
Why are beta brain waves so fast?
You can imagine, that in active thinking there needs to be more brain activity in order to process information faster and so, the brain waves are also faster. The beta brain waves are one of the four main brain waves (the other ones are alpha theta and delta brain waves). Our brain is at all times in a specific brain wave state.
How do beta waves work in meditation?
In meditation, it is very advisable to make the meditative experience "conscious" by talking about it, writing it down, and so on. Normally, one slows down the brain and ideally, all the beta brain waves vanish (this is not true for analytical meditations and for meditations that involve words by ...
What are some examples of electrical activity in the brain?
Depending on the current situation, there is a high electrical activity in the brain or not. Typical examples are active thinking and sleeping. During active thinking, many neurons send off electrical impulses, whereas in sleep, there only little brain activity and so, there is also little "communication" amongst the neurons.
Is beta a motivation boost?
Motivator: It is said that increasing beta waves in students, who are demotivated with studying, can be a true motivation boost. I can confirm (amongst many other people) this claim. If you are ever bored with homework and exams I recommend you listening to beta binaural beats.
When do beta waves occur?
Beta waves play an active role in network coordination and communication and do not occur until three years of age in humans. In a state of stress, a phenomenon called ‘Alpha blocking’ can occur which involves excessive Beta activity and little Alpha activity.
What is the purpose of higher levels of beta waves?
Higher levels of Beta waves are found to channel a stimulating, arousing effect, which explains how the brain will limit the amount of Alpha waves if heightened Beta activity occurs.
How many brain waves does Lucid have?
Something we hear quite often within the Lucid team is the expression, “I’ve just had a brainwave!”. Well the truth is that your brain actually has 5 brainwaves, each one a distinct electrical pattern which operates even when you’re fast asleep. For years, doctors and scientists have studied these brain waves using an EEG or electroencephalograph, a complex device which tracks the neuro activity known as brainwaves over 5 different channels. Lately, these devices have been simplified into consumer devices by our friends at Emotiv. Read more about the Emotiv hardware here.
What waves do you get when you are fast asleep?
If you’re fast asleep and mid-REM cycle, you’ll be exhibiting higher levels of Delta and Theta waves.
Why do we feel theta waves?
Theta waves are also linked to us experiencing and feeling deep and raw emotions, therefore too much theta activity may make people prone to bouts of depression. Theta does however has its benefits of helping improve our creativity, wholeness and intuition, making us feel more natural.
Why do beta waves restrict alpha?
In this scenario, the Beta waves restrict the production of alpha because we because our body is reacting positively to the increased Beta activity, usually in a state of heightened cognitive arousal. Frequency range: 8 Hz to 12 Hz. High levels: Too much daydreaming, over-relaxed state or an inability to focus.
How do you increase beta waves?
Beta waves increased by drinking common stimulants such as caffeine or L-Theanine, or by consuming Nootropics or cognitive enhancers such as Lucid. Think of Beta as the ‘get shit done’ state of mind. Frequency range: 12 Hz to 40 Hz. High levels: Anxiety, inability to feel relaxed, high adrenaline levels, stress.
