The neurological centre the brain has always been an organ intriguing to any seeker of knowledge. Brain is the centre not only of thought but also behavior. It is an amazing network of neurons with their synapses which is monitors reticular maze. All our actions, thoughts, are manifestations of the electrical impulses moving through the brain cells. These electrical impulses move with a certain speed known as Frequency, which is measured in Hertz (Cycles/second). The speed or the frequency of these electrical impulses or the excitation of the neurons is reflective of the calmness or excitable behavior of an individual. It is definitely surprising to observe the different behavioral patterns of people in various situations. In this chaotic lifestyle, the study of brain waves has in reality been beneficial to many psychiatrists and trainers. The state of mind and consciousness is the result of four types of brain waves which have been extensively studied. The four types of brain waves are:

  • Alpha (Range: 7-14 Hz): These waves are produced in the brain when the mind is relaxed, and is in a day dreaming state, it is detached. The Alpha waves increase the concentration, focus, and provide health benefits. These are considered to be a link between the conscious and subconscious mind leading to a meditative mind.
  • Beta (Range: 14 -32 Hz): The thinking mind and the conscious thought process produce these waves. These waves are the seat of alertness, and critical thinking. The higher level of frequency range of Beta waves, result in insomnia, nervous breakdown, feeling of anxiety and stress. Also, the most common brain wave that is generated is the Beta wave.
  • Theta Waves (Range: 3.5-7 Hz): These waves are produced by the subconscious mind and effect the brains functions such as long term memory, retention and help in increasing the creative learning capacity of an individual. During REM sleep, these waves are supposed to elicit rapid eye movement. Also, theta waves are the threshold of meditation and spiritual transcendence.
  • Delta Waves (Range: 0.1-3.5 Hz): The Delta waves are produced when the mind becomes unconscious, during trance state and deep meditative state thus a loss of bodily awareness. Of all the types of brain waves, these have the largest amplitude and are responsible for mental processing of information.

 The study and awareness of the Brain waves are instrumental in living a controlled life. An aware individual can practice the control of the brain waves and also is aware of the state of mind, calm or chaotic. The brain wave pattern is an important basis of learning and memory. The study of these brain wave patterns help the neurological researchers to interpret the electrical impulses of the neurons and help in the study and treatment of the learning disorders or other behavioral afflictions or even degenerating diseases such as amnesia, Alzheimers or other memory related disorder. The studies on Brain waves are concentrated not only on the memory waves but also the Alpha waves which help to improve the ability to learn, reduce stress and help in thinking differently. Finally, the Brain wave study has been an important tool in enhancing memory and for brain training exercises, to improve awareness and attention span of an individual.
