Patterns of Brain-Wave Activity
 
Research suggests that the Hypnotic state creates changes in the Brain-Wave. Your brain works with different frequencies and produce a different pattern of electromagnetic brainwaves whether awake, asleep, meditate or you are in the hypnoses. The many billions of brain cells create the field of electricity, which synchronize with each other. These brainwaves provide your state of consciousness’, making you feel alert, relaxed, creative, sleepy etc. Your brain is made up of billions of brain cells called neurons, which use electricity to communicate with each other. The combination of millions of neurons sending signals at once produces an enormous amount of electrical activity in the brain, which can be detected using EEG . The combination of electrical activity of the brain is commonly called a Brainwave pattern, because of its 'wave-like' nature. 

Our mind regulates its activities by means of electric waves which are registered in the brain, producing electrochemical impulses of varied frequencies, which can be registered by an electroencephalogram.

There are four patterns of brain-wave activity. These waves can be graphically represented by use of the electroencephalograph (EEG). The frequencies are as follows: 
  • Alpha (9 – 14 Hz): Rest, reflection. 
  • Beta (16 – 24 Hz): Concentration 
  • Theta (5 – 8 Hz): Relaxed, daydreaming, hypnosis, meditative and creative states 
  • Delta (1.5 – 4 Hz): Deep, dreamless sleep

THE ALPHA BRAIN-WAVE STATE (8-13 cps)

The alpha state is state of beginning relaxation. The diagram of the alpha state illustrates high frequency, low amplitude brain waves. In this state, the mind is relaxed but alert. It is a state of passive awareness, serenity, of physical and mental relaxation. Emotional sensations in the alpha state include a sense of well-being, tranquility relaxation. In the alpha brain-wave state, a person is capable of accelerated learning, healing of psychosomatic illnesses, memory improvement.

THE BETA BRAIN-WAVE STATE (14-30 cps)

The normal, awake, conscious activity of the brain is the beta brain-wave state .It is a state of full alertness, physical activity and excitement. Emotional sensations in the beta state include fear, 
anxiety, tension, anger, worry, hunger, excitement. A transition occurs with the onset of Hypnosis. As you begin to relax during the hypnoses your brain wave will change from beta to alpha brain-wave. 

THE THETA BRAIN-WAVE STATE ( 4-8 cps)


The theta state is one of tranquility, creativity and very deep relaxation. Emotional sensations experienced in the theta state include restful alertness, uncertainty, daydreaming and deep 
tranquility. 

THE DELTA BRAIN-WAVE STATE (.05-4 cps)

The delta brain-wave state is not reached in Hypnosis. It is experienced in the deepest stages of sleep. It is a state of total unawareness, of unconsciousness. There are no feelings in this state; 
therefore no emotional sensations are associated with the delta.
