Electric and Magnetic brain waves are created from each and every word we think. These waves have different frequencies and amplitudes. These brain waves carry substantial information about the activity or word being processed and then recognize them. Different methods of imaging brain activity such as positron emission tomography, functional magnetic research imaging and magnetoencephalography tomograpgy have immerged as valuable source of knowledge, especially about where in brain different kinds of activity occur. This paper identifies the user’s adeptness on brain control systems and ability to control brain generated waves in a closed neurofeedback loop. Brain computer interfaces are communication devices which allows user to transmit commands to a logic processing circuit on the basis of brain activities or waves.
