The brain is a multifaceted entity which has the ability to make the mind and body perform its functions. This is comparable to conducting a symphony of orchestra that has to blend in tempo, choice of music and volume. According to research, the brain’s electrical signals or brain waves are changeable and people can be taught how to change them. So, how do you actually train the brain waves?
Brainwaves are defined as the electrical operation of the brain. As the brain functions, it sends electrical impulses that bring forth quick voltage fluctuations. These electrical frequencies vary depending on the person’s state of mind. Brainwaves are measured by electronic equipments while people are being examined on different states — sleeping, meditating or actively thinking. Thus, it is important to know the brain wave frequencies during these states.
There are different types of brain waves:
1. Beta. Beta brain waves have frequency range of 14 to 100 Hz. This is the brain wave frequency for those who are in the normal waking stage. This further includes those experiencing alertness, cognitive thinking, action, analysis, arousal, anxiety and fight or flight response. The brain released the following hormones during this brain activity: cortisol, epinephrine, insulin. Beta brain waves also indicate constriction of the arteries, increased heart rate and respiration and decreased digestive action.
2. Alpha. Alpha brain waves have frequency ranging from 8 to 13.9 Hz. This is evident with people in the relaxed waking state. This is further observable when there is relaxed focus, creative problem-solving, super learning, pre-awake or pre-sleep drowsiness, access to subconscious mind and spiritual awareness. Hormones released during this stage are: serotonin and nor-ephinephrine. Alpha brain waves also indicate activation of parasympathetic nervous system, body repair and rejuvenation, opening of arteries, slow deep breath and slow heart rate.
3. Theta. Theta brain waves have frequency ranging from 4 to 7.9 Hz. This is evident with people in the dream or REM sleep. When people have this type of brain waves it indicates that they are in deep/creative flow or contact with the “muse” deep meditation, access to the unconscious mind and profound spiritual awareness. The theta waves also indicate an increased production of catecholamines, improved memory and increased capacity for learning. Hormones that are evident during this stage are melatonin that causes an integration of emotional change.
4. Delta. Delta brain waves have frequency that ranges from 0.1 to 3.0 Hz. This is experienced by people who are in deep dreamless sleep and loss of body awareness. Delta brain waves are further indicator of slowest heart rat, significant increase in melatonin production, deep physical healing and rejuvenation, deep integration of positive mental and emotional change.
Individuals with ADHD normally have Theta type of brain waves. Thus, people diagnosed with ADHD have difficulty in controlling attention and movement. Comparingly, persons without ADHD usually have beta waves which indicate concentration, focus and attention. This is the opposite case for those with ADHD when they are asked to do tasks that require focus and attention; they tend to release theta waves which are normally seen in people in the daydream state. Therefore, persons with ADHD will have difficulty paying attention to the tasks on hand. However, this is also the very same reason why individuals with ADHD may have difficulty controlling their focus but are found to be creative in different fields like the arts, movies, painting and others.
