1- Why We Need to Know about Brain Waves?
Research has discovered that the human brain operates at different speeds called frequencies. These speeds are different according to many influences, internal or external. These influences can change the speed of your brain waves. The speed of your brain waves can in turn influence –negatively or positively – your personality, your attitudes and your life. Brain waves can affect your: mood, memory, mental ability, energy level, ability to relax, learning ability, success level, healing, immune system, and your general level of happiness. By changing our brain waves, we can reach our goals more easily. We can change our emotional states if we know how to change our brain waves.
This topic will answer many questions, like:
Have you ever wondered why some people seem to be always in a good mood? Have you asked yourself why some persons look to be happy for no obvious reason? Is happiness connected to your brain speed more than to your achievements? Why many rich persons become miserable in spite of their recent material accomplishments while other poor persons are in a better mood in spite of their poverty? Why the intelligent and educated person sometimes suffer from repeated cycles of negativity or depression while the illiterate person is usually happier? How is it that the person under deep hypnosis, under Delta state, can remember everything that happened to him/her even at a very early age, but at the awake state they can't remember those memories? Can we use brain waves for super learning techniques? Why children are usually happier and enjoy accelerated learning capabilities much more that adults? Can we use different brain waves to treat depression or for general healing? Can different levels of brain waves lead to different states of consciousness?
Finally: Is it possible that we humans also communicate at the unconscious level, by electromagnetic communication system that is based on brain waves?
Of course, happiness, good mood & optimism are determined by more than one factor, but the common factor is –by and large- the same. Your conscious awareness and also your unconscious mind UM is directly linked to the state and speed of your brain waves. This is not to say that it is better to avoid education or business simply because it has sometimes negative effects, but rather an awareness call to how to benefit and use our brain waves to our advantage. Understanding your brain waves will help you to use the power of the mind for your goals both at the conscious and the unconscious level. It will also allow you to reach different conscious levels. Neuroscience today, is discovering many secrets of brain functioning through the patterns of brain waves.
2- What Are Brainwaves?
Let us first define and understand the main brain waves of the person,and before we get to the details, we need to know briefly about the human brain and its functioning.
The human brain is very extraordinary and fascinating. Research shows that the brain has between 100-200 billion nerve cells called neurons. Each of these neurons is connected to other thousands of neurons. The number of connections between neurons in the human brain is more than the stars in our galaxy. The neurons produce electricity when they communicate with each other. They pass information to each other using tiny electrical currents. When millions of neurons communicate with each other at once, they produce strong electrical activity. Some researchers estimate that an active brain can produce 10 watts of electrical activity. This is why the brain is called an electromagnetic organ. Brain electrical activity is described in terms of brain waves. Brain waves are like radio waves as a form of electromagnetic energy that travels at the speed of light. Like radio waves –and all waves- brain waves have electrical frequencies. A frequency is the number of times a wave repeats itself in a second. It is like the frequency of your radio. The difference between radio waves, other electromagnetic waves such as x-rays and brain waves is in their frequency. The frequency is measured in cycles per second or Herts (abbreviated Hz), which means the number of cycles the wave travels in one second. A slower wave means a lower Hz number. Radio waves have a high speed of 50-1000 mega Hz, while the brain waves have a frequency between 1-100 Hz. Brain waves can be measured by using sensors or electrodes placed on the scalp. Sensitive medical devices are able to measure and record brain signals.EEG(electrocephalogram) is one of many devices that measure brainwave activity. Other devices include MRI, MEG & NIRS which measures blood flow of the brain.
Brain waves are formed when the neurons communicate with each other. This happens whenever we use our brain,for example when we think about something. Our thoughts are a bio chemical and electromagnetic energy that causes neurons to fire. The speed at which these neurons fire will create a frequency that can be detected by EEG device as waves. Brain waves can be produced not only by thinking, but also by different emotions, and behaviors. Brain waves have a tendency to change according to what we are doing, mentally or physically or emotionally. On the other hand, the current speed of the brain also determines our mental, physical and emotional state. They are directly linked to each other: the speed and the state, meaning either one can be the cause and also the result. Therefore, it is very important to know when and why brain waves change, and equally important to know how we change once the brain waves begin to change. We can also view brain waves as altered states of consciousness. Brain waves have different patterns or speeds. You can know the state of a person simply by noticing their brainwave speeds. Neuroscience has discovered 4 main different speeds of brain waves: Beta, Alpha, Theta and Delta. Gamma brain waves were discovered only recently, and very little information are known about this magical brainwave. The effects of different brain waves are clear according to which dominant speed you are in, in a given moment of time. For example, if your dominant brainwave now is Beta which is the high speed wave, then you are wired or alert or even nervous. Theta brainwave means you are so relaxed that you may fall asleep anytime. If you want to move your state from being anxious to total relaxation, all you have to do is to move or change your brain speed from Beta to Theta, by ways of different tools. This means brainwaves can be the cause of your state or the result of your state.
Before we explain in detail the different categories of brainwaves, it is important to know that these brainwaves change according to what we are doing, feeling and thinking. Brain speeds vary depending on your activity during any 24 hours. To be able to shift between different brainwaves is a symbol of a healthy person. For example, if you are sleeping, without dreams, you are in effect in the slowest brainwave, the Delta state. Whenever the alarm clock starts ringing and you wake up, your brain speed shifts to a quicker speed, the Theta state. In this state, you are half asleep or very relaxed. You may stay in this state for about 5-15 minutes. When you get up, you are likely in the Alpha state, a faster brainwave activity. Finally,when you drive your car, it is normal that you are in the Beta state, being fully alert.
Research discovered that all brainwaves can be present at all times, but at different levels. This means if you are driving your car and the Beta state is dominant at that time, the remaining three brain states can be present but at a much lower level. Therefore, our brains do not restrict us to only "one" brainwave state. Our brain activity is the combination of all frequencies at any given point of time, but with different quantities and levels. Our brain has the ability to shift from one state to another, depending on different influences. However, some factors can cause the brain to be "stuck" in one state, usually a negative state, and this may cause mental disorders such as depression. Emotional stress is one major negative factor. These factors will be explained later.
Generally, the slower the speed of your brain waves, the better state you will be. The only exception, is the Gamma state which is the highest speed and in the same time the best positive state that you can be.
