The actual ability of the brain to remember things is not the whole to blame as far as concentration is concerned. In fact, it is not the one to blame as far as concentration is concerned. You will need to apply some efforts so as to concentrate. Brain waves and the study of them is an interesting thing to help you achieve various end results as you may desire in one time in life or another. You may need to be versed with the working of the brain waves and the technology that modifies them so as to know to apply them in your life.
You need to be acquainted with the fact that your brain is an electrochemical organ. This means that it will generate electrochemical energy as it works on and on. In fact, brain will generate about 10 watts of electrical power while at full capacity. The electrochemical waves are necessary to have the brain cells connect with each other. There are millions of cells in the brain and for them to connect at one time, you will generate up to about five to 50 million recorded volts if an electrode is placed on the human scalp.
The electric power of the brain is produced in a manner that is characteristic of the human brain. Brain waves are what display the electrical activity, and the waves can be categorized as from the most to the least active. Beta waves are generated when the brain is aroused and engaged in activities. These are the fastest category among the four and are of low amplitude. They range between 15 to 40 cycles per second and depict a strongly engaged mind. In beta, you will be in an active conversation and at high beta when in debate. When engaged in conversation and speech as well as teaching, you will be in beta.
Alpha is the second in order of frequency alpha, unlike beta, represents non-arousal and the waves are in higher amplitude than the beta but slower. The frequency is in between 9 to 14 cycles per second. An alpha state is experienced by a person who has completed a task and is seated to relax. An alpha state is used for meditation. This is for example taking a break to relax in a garden.
Theta brainwaves are characterized by very low frequency and very great amplitude and are produced at in between 5 to 8 cycles per second and a person in theta state is characterized by daydreaming after completion of a task. Freeway driving can induce a state of theta such that the drivers will not be able to remember the last five miles they have just driven. At theta, you can get very good ideas. Theta state can occur while at the shower or tub. The knowledge on how you can harness on your brain power and the waves induction process is very necessary to increase productivity, whether it is in work or relaxation. Delta depicts frequencies of the range 1.5 to 4 cycles per second and is of greatest amplitude but slowest. Having a deep dreamless sleep means that you have achieved the lowest frequency possible for the brainwaves.
