Brain Waves and You, Lights and Flashing

WARNING IF YOU ARE EPILEPTIC OR ARE TAKING PSYCHOACTIVE DRUGS DO NOT USE BRAIN WAVE GENERATORS OR HEMI-SYNCH PRODUCTS UNTIL YOU CONSULT YOUR DOCTOR.
All of us have them. No they are not waves like you see in the ocean, but they are waves in that your brain produces activity in such a way that they are read like waves on a graph. When the brain is active our minds are constantly adapting to our environment. Stress, anxiety, activity, and work can all effect our brain wave activity. The brain works in stages where there are certain frequencies of activity that are associated with different mental states. These mental states can be observed by neuro-physicists and health scientists by using EEG technology. Electrodes hooked up to the brain can read the subtle chemical electrical impulses produced by these states of mind. Doctors use this information to find abnormalities in people's brain activity which may show them areas of brain damage such as in the case of epileptics and those who suffer from flashing light sensitivity.
But now we not only can read brain wave states but we can influence these states in the form of flashing light and beating sound to produce calming effects or even in some cases incapacitate a felon. This type of technology has been around for thousands of years. Tribal people used beating drums, and fire to produce altered states of consciousness along with the use of hallucinogenic drugs. They believed that these states of altered consciousness would allow them to reach a spiritual mental level beyond the world we experience in waking life. Today we know that flashing light and alternating beats effect the way our brains work. Our brains are halved in such a way as to create two hemispheres. One hemisphere is the visual or creative brain (the right brain) and the other side (the left side) is the cognitive mathmatical and factual part of the brain. When light and sound are produced in such a way as alternating flashes and beats the brain wave activity seems to synchronize with the beats and flashing light. This creates an altered state of consciousness.This process is known as hemi-synch or hemispheric synchronization.The type of flashing and beats effect the brain wave states in that the brain waves are measured in hertz. Here we will look at the brain wave patterns and their associated meanings and mental states.
Brain Wave States:
Delta waves are between 1 and 4 Hz. This state is associated with slow wave sleep patterns in adults. It can point to subcortical lesions in the metabolic regions of the brain.
Theta is the frequency range from 4 Hz to 7 Hz. Observed in people who are having creative expression, artistic creativity, sexual arousal, and child like day dreaming.
Alpha is the frequency range from 8 Hz to 12 Hz. Alpha waves have been recorded in deeply relaxed meditative states.
Beta is the frequency range from 12 Hz to about 30 Hz. It is the dominant rhythm in patients who are alert or anxious or who have their eyes open and are participating and reacting to their environment. (Awake State)
Gamma is the frequency range approximately 30–100 Hz. Gamma rhythms are associated with mental concentration and work.
So what does this information do for you? Well you can buy or you can watch and download videos, mp3's, and mind machines that produce these desired effects. I have included some www.youtube.com videos on this hub that you can use to experience these effects.
