    The neurons of the brain fire in varous patterns. The signals travel at various speeds.

    The wave frequency is designated by letters of the Greek alphabet:

    -- alpha

    -- beta

    -- gamma

    -- delta

    -- theta

    Brain waves can be measured and recorded by electroencephalography (EEG). Long-term meditators self-induce high-amplitude gamma synchrony during mental practice. Those who practice Zen have been demonstrated to produce theta waves.

    The restorative phase of sleep is during slow wave sleep which corresponds to the gamma, delta and theta wave pattern of meditation.

    Alpha waves are those between 7.5 and thirteen(13) waves per second (Hz). Alpha is usually best seen in the posterior regions of the head on each side, being higher in amplitude on the dominant side. It is brought out by closing the eyes and by relaxation, and abolished by eye opening or alerting by any mechanism (thinking, calculating). It is the major rhythm seen in normal relaxed adults - it is present during most of life especially beyond the thirteenth year when it dominates the resting tracing.

    Beta activity is 'fast' activity. It has a frequency of 14 and greater Hz. It is usually seen on both sides in symmetrical distribution and is most evident frontally. It is accentuated by sedative-hypnotic drugs especially the benzodiazepines and the barbiturates. It may be absent or reduced in areas of cortical damage. It is generally regarded as a normal rhythm. It is the dominant rhythm in patients who are alert or anxious or who have their eyes open.

    Gamma is the frequency range approximately 26–100 Hz. Gamma rhythms appear to be involved in higher mental activity, including perception, problem solving, fear, and consciousness

    Theta activity has a frequency of 3.5 to 7.5 Hz and is classed as "slow" activity. It is abnormal in awake adults but is perfectly normal in children upto 13 years and in sleep. It can be seen as a focal disturbance in focal subcortical lesions; it can be seen in generalized distribution in diffuse in diffuse disorder or metabolic encephalopathy or deep midline disorders or some instances of hydrocephalus

    Delta activity is 3 Hz or below. It tends to be the highest in amplitude and the slowest waves. It is quite normal and is the dominant rhythm in infants up to one year and in stages 3 and 4 of sleep. It may occur focally with subcortical lesions and in general distribution with diffuse lesions, metabolic encephalopathy hydrocephalus or deep midline lesions. It is usually most prominent frontally in adults (e.g. FIRDA - Frontal Intermittent Rhythmic Delta) and posteriorly in children e.g. OIRDA - Occipital Intermittent Rhythmic Delta).

    With the hectic pace and demands of modern life, many people feel stressed and over-worked. It often feels like there is just not enough time in the day to get everything done. Our stress and tiredness make us unhappy, impatient and frustrated. It can even affect our health. We are often so busy we feel there is no time to stop and meditate! But meditation actually gives you more time by making your mind calmer and more focused. A simple ten or fifteen minute breathing meditation as explained below can help you to overcome your stress and find some inner peace and balance.

    Meditation can also help us to understand our own mind. We can learn how to transform our mind from negative to positive, from disturbed to peaceful, from unhappy to happy. Overcoming negative minds and cultivating constructive thoughts is the purpose of the transforming meditations found in the Buddhist tradition. This is a profound spiritual practice you can enjoy throughout the day, not just while seated in meditation.
