Cybernetics is nothing but linking of human thoughts with that of cybernetic machine. Thus we are controlling the machine just through thoughts. Cybernetics is thus the commingling of the most difficult work of thinking to the most effective tool to execute it, the machine. In a nutshell it may be stated that just by thinking we could make a machine work.Brain is source of all thoughts. This principle organ produces impulses that are of constant amplitude and that are a pulse modulated wave. These impulse passes through the nerves. The nerve acts like a transmission line and does not alter the impulse. But the synapses, a fiber like structure present at nerve end converts it to other form like integrated, amplified signal etc.,.Our aim is to use these synapses for tapping the signal en route. The synapses are a fine hair like structure. A sensor placed at this juncture can receive the signal from the synapses. From the synapses these sensors take control of the entire process. these sensors command the externally placed computer to act according to the signal received. Then the computer may take control over any system. For instance, if I would like to switch on a light from the next room, without any switches or gadgets in between then being a cybernetic human I may think to switch on the light. The thought signals will activate the sensor in turn controlling the computer to do the desired job.
