Artificial hearing, in its earlier form was a microphone, and then a hearing aid. An implant within the head, dramatically increases its potential. It is this type of hardware implants that cybernetics encompasses. A merging of the biological and electronic environments, if you will.

People who suffer physical injury or disease, that render them into a limited field of possibility, will be the initial beneficiaries. It is said that there is an area of the brain called the paroidal reach region, that can function, where complete paralysis exists. It runs through the plan before a physical act occurs. Some believe that where this region is functional, external manipulation is possible. A processor can be implanted; it picks up on the electrical firing activity produced, and communicates this information wirelessly, to an external device.

The theory is that if we can think it, well then we can do it.

Wasn't it Napoleon that said "If we can perceive it, we can achieve it". I really doubt though, that he was referencing cybernetics. However, it is well known that the hardware to device communication is possible.

It is also known that the device control is possible. Modern machinery from production machinery to marine vessels have what is known as dynamic positioning control. Research vessels can hold position to within five inches of any point, in the Atlantic or other oceans, under normal sea conditions. Twenty years ago, this tolerance was two foot, or feet. Special electrical motors ( though no longer considered special ), make this possible. The older technology was mechanical gearboxes that had a limited reaction time/control.

So, these or similar motor technologies, can be used for robotic arms, legs, eyes, ears, switches, switches for switches, internet connection, or indeed anything that a futuristic mind can contemplate.

What is not understood entirely, is the brain coding. Can it be figured out? Yes!
