The brain produces an electromagnetic wave throughout the day and the strength of this wave depends on the activity of the brain. It is said that this wave is a weak wave which does not cover a greater distance. But I do believe that it is like the radio wave in the distance it covers and frequency it possesses. I do believe that there is a communication between individuals through electromagnetic wave (brain wave) and a gas (Nitric Oxide) produced by the brain. This can be observed in our daily experiences. This can also help us understand that as a computer can receive and record the brain waves, so an individual can also receive and integrate these waves and it is being decoded to release the message it contains. In this respect, it can be said that the state of consciousness in an individual can be understood by another through concentration.
