The brain is composed of billions of brain cells called neurons. Neurons use electricity for communication. Brainwave is commonly known to cause an enormous amount of electrical activity in the brain, produced by the combination of millions of neurons sending signals at once. This brain wave activity can be detected using EEG (electroencephalograph) and usually describe regarding the following frequency bands:
GAMMA is the fastest brainwave and is essential for processing and linking information during cognitive thought. An exceptional level of gamma brainwave activity is related to intelligence, enhanced memory and the feeling of contentment. The deficiency implies otherwise, like learning difficulties and cognitive decline.
BETA has also shown fast brain wave activity. It is present in problem-solving, processing information or feeling anxious. Excessively high beta brain waves indicate that an individual may be suffering from a condition such as anxiety, obsessive-compulsive disorder, irritability, agitation, insomnia and bipolar tendencies.
ALPHA appears to bridge the conscious with the subconscious, usually associated with a state of relaxation. Promotes mental resourcefulness, aids in mental coordination, and enhances the sense of relaxation and fatigue. It allows switching from one task to another which enables to complete the given task efficiently. Excessive alpha activity produces agitation, is fidgety, unorganized, have unfinished tasks which are commonly experienced symptoms of ADD and ADHD.
THETA is classified as moderate activity and is present between waking and sleeping time. Creativity, daydreaming, fantasizing, intuition, recall, and switching thoughts are connected with theta brain waves. High range of theta brain wave is often found when engaging in complicated problem-solving. Excess theta waves in regular waking hours reflect problems with focus and attention, head injuries, and learning disabilities. Excessively low theta frequency is the reciprocal effect of those having ADD and ADHD.
DELTA is slower brain wave, which is mainly present in deep and the non-aroused state. If high focus and peak performance are required, delta waves stay decreased. That happens inversely to individuals who end up being diagnosed with Attention Deficit Disorder. Their brains naturally increase delta waves rather that decrease it when trying to focus. The inappropriate delta response inhibits the ability to focus and maintain attention.
Through technology, a medical practitioner can now know the area of the brain that is malfunctioning which is a precious tool in diagnosing ADD and ADHD.
Brain damage can result in attention deficit disorders; thus, the concentration is affected. Stimulating the ADD and ADHD brain to concentrate is by optimizing the brain functions, which is an effective strategy of Nootropics.
