Meditation to Increase Brain Function

Meditation is a discipline where the mind is focused either on an object or on breathing. It has been described as ‘self regulation of attention, in the service of self-inquiry, in the here and now.”

There have been numerous articles in major magazines as well as in medical journals of the positive benefits of meditation from reducing stress to healing the physical body. Meditation has been known in eastern religions for more than 5,000 years as a quest for spirituality.

Today, there are different types of meditation from the spiritual to psychophysical disciplines, which emphasizes the development of a high degree of mental concentration.

In one small study by the University of Wisconsin-Madison, 25 Madison-area employees went into an eight-week meditation training program to study the mind-body connection. After training, results showed nearly a 50 percent increase in electrical activity in the left frontal area, (the part of the brain associated with positive emotions and anxiety reduction,) of the brain. The study also included the administration of flu shots to the employees. Sixteen other employees also received the shots, but received no meditation training. The study found that the meditators on average had a five percent increase in flu antibodies and some had an increase of up to 25 percent. This goes far in proving meditation can have a positive affect on the body and the mind.

It has been found through study that meditation actually changes brain waves. Because the brain is an electrochemical organ and works off electromagnetic power, meditation will alter the brain waves.

Science has classified four categories of brain waves. When the brain is aroused and active, usually during the activities of every day life, you are using the fastest brain wave, beta. The frequency of beta waves are generally from 15-40 cycles per second.

The next brain wave is called alpha, which are slower and indicates someone who may be sitting down and resting after completion of a task, taking a walk in a garden or meditating is considered to be in an ‘alpha state’ or using the alpha brain wave. The frequency of alpha waves are between 9-14 cycles per minute.

The third brain wave is called theta, which is even slower than the alpha brain wave. Theta waves are considered active when you are daydreaming. If you are driving down a highway and can’t remember the last few miles, you are or were in a theta state. The repetitiousness of a task can often allow us to complete the task without thinking about it. Theta cycles are between 5-8 cycles per second.

The last brain wave is called delta. Delta waves are shown during a deep and dreamless sleep. The cycle range is between 2-3 cycles per second.

Brain waves can also be changed by sound. Music can change the brain waves from active to relaxed. Through external stimuli, such as a tone playing in one ear at 440 hertz and a tone being played at 448 hertz in the other ear, the person listening will hear 8 hertz per minute. Although not really a ‘tone’, it is created within the brain stem which synthesizes the two tones, bringing together the right and left hemispheres of the brain.

Meditation in itself changes brain waves and this helps one to learn how to relax, which in turn will allow one to be able to better deal with everyday stresses and emotional issues. It could also lead one into becoming more self-aware and more observant of those things around us.

What is Meditation?

Meditation is healthy, safe and affordable. In fact it’s free. The only expense you’ll have is a meditation mat, which isn’t especially necessary-at least from my experience. Meditation has been around for 5,000 years, and was originally a spiritual component of yoga. Through the years non-yogis adopted it, intuitively sensing and connecting the practice with greater peace of mind.

The Reason Why Meditation Doesn't Work

The title of this article may seem a little strange. How can I say meditation does not work when there is a vast amount of research which seems to show that it does? Much research, in the scientific field, points to the fact that meditation can; make you healthier (both emotionally and physically), make you look younger, bolster the immune system, help you recover faster after operations, reduce stress, help you to live longer, remove past emotional issues and alter negative beliefs.

Make Meditation Work With Binaural Beats

Even those who have never heard of binaural beats have elementary knowledge of meditation though it may be slightly misguided. Although meditation is becoming more popular in the western world it has been practised for thousands of years in the East. It is only recently that binaural beats have been used to create the same effect.

Does Holosync Work?

When everyone else was listening to Guns N' Roses, wearing tight jeans with baseball boots and perming their overgrown hair, a man called Bill Harris was busy creating a truly unique personal development product - Holosync. Harris's Holosync product centred on the idea that you could listen to a CD and enter a state of meditation akin to that of a Zen Buddhist Monk.

Problem Solving Meditation

Problems? Sleep over it and daydream the solution in less than twenty minutes. Meditation is a key practice to help you keep your mind focused on what ever you decide to think to. And an unemotional, objective mind is a lot more efficient at problem solving than a mind distracted by the emotional burden of fears and hopes.

Meditation Drawbacks - Risks Associated With Meditation Practice

Meditation is the method of choice for spiritual practice in many religions. The benefits of meditation don't stop at this level though. Your mind and body benefit immensely from meditation. There are few drawbacks though, one should be aware before taking up meditation. The problem is ... within us. We all carry a baggage of traumas buried deep down in our subconscious minds. These are unpleasant events, consequence of our own or other people actions that affected us. Our minds try to protect us by covering up these experiences. In other words, we forget. Or do we?

Brainwave Meditation - How It Works

Brainwave meditation is achieved by external stimulus (mostly sound signals) that matches the brainwave frequencies specific to deep meditation states. The brain is exposed (e.g. stereo headphones) to two different sound signals (binaural beats). Further on the brain integrates these signals in a process called brainwave entrainment (synchronization) with the differential frequency as the output. This frequency produces similar effects with classical meditation techniques.
