"This mystery mechanism of human transformation is neuronal recycling, coined by neuroscientist Stanislas Dehaene, wherein the brain’s innate capabilities are harnessed for altogether novel functions."

"Neil Harbisson introduces himself as the first cyborg ever legally recognized by any Government (2004). He was born colour-blind; so he can only see in black and white (Achromatopsia disorder). An electronic device implanted in his neck allows him to translate colours into sounds. The camera that hangs from his forehead 24/7 was accepted as part of his British passport photo. By that very fact, the camera became congenital and not prosthetic to his body anymore. Thanks to it, light frequencies are captured and translated into sound frequencies by the chip, which in turn sends them to his brain. He literally listens to colours with his electronic eye. A standard eye perceives light, tone and saturation. Harbisson’s organic eyes perceive light, but tone is converted into sound, and saturation into volume through his third eye."

"Vikings worldwide seem to have taken up a fashion for painful but impressive modification of teeth around the 10th century AD"

"a prosthetic chip that uses electrodes to enhance and expand their memory abilities. The chip is capable of storing neural signals, basically functioning as an electronic memory"

"Could electronic components made from human blood be the key to creating cyborg interfaces? Circuitry that links human tissues and nerve cells directly to an electronic device, such as a robotic limb or artificial eye might one day be possible thanks to the development of biological components."
