### Gamma brain wave: This brain wave is involved in performing high-level tasks such as cognitive functions.. Gamma waves are important for learning, memory and information processing.. There is an idea that 40 Hz gamma waves (the highest brain frequency) are used to combine the senses with understanding and learning new concepts. More than usual amounts of gamma brain waves cause: stress, anxiety and high irritability.... Lower than usual amounts of gamma waves cause: ADHD hyperactivity, depression, specific learning disorder SLD.... The right amount of gamma brain waves causes: integration of the senses, cognition, information processing, learning, understanding, improvement of the brain's REM stage.. ### Beta brain waves: Beta brain waves are known as high-frequency, low-amplitude waves seen mainly during wakefulness....During conscious thoughts, rational thoughts, and during sensory activities, having the right amount of beta waves allows us to fully focus on our schoolwork or work tasks....Excessive amounts of these waves lead to experiencing high levels of anxiety or severe stress..From alertness.... When you drink coffee or receive other stimuli, your brain's beta function naturally increases.... These waves are at a fast frequency, often during the day during people's conscious activities, such as: important thoughts, writing, reading and socializing.... The range of beta brain waves is: 13-30 Hz (high).. Lower than normal amount of beta brain waves. Beta brain causes: concentration of alertness, improved memory and ability to solve problems... When you close your eyes and are in a state of complete mental, physical and spiritual relaxation, the brain waves enter the alpha wave frequency between the alpha wave frequency. The frequency of this wave is half the frequency of full wakefulness waves, that is, between 8 and 12 cycles per second.. Alpha waves are produced in children from about one and a half years of age, and with the growth of these waves, the power of learning also increases... At the age of 6 and 7, the most brain waves are alpha waves.. That is why children at this age have more power to learn... ### Theta wave: In the theta wave, the frequency of brain waves is reduced to 3 to 8 cycles per second... If the time the brain is in the alpha state is prolonged, we are preparing for sleep.... In the first minutes of sleep, brain waves are on the theta wave.... Theta wave plays an important role in creativity and increasing intuitive and sensory perception in people with high concentration.. Theta wave amplitude leads to slow reaction time and inability to learn... Also seen they become.... but in adults it appears after falling asleep.... ### Delta wave (Δ): These waves, which are the slowest waves of the human brain, have a frequency of less than 3 cycles per second... By changing the frequency of the brain from theta wave to delta wave, we enter a deep sleep; In other words, it can be said that our deep sleep happens when our brain waves are on the delta wave.. In this case, the activity of our conscious mind reaches zero and our subconscious mind takes full control of the body.. Months is a delta wave that under normal conditions decreases with age...
