•A cyborg is a cybernetic organism.
•The term is defined as an organism that is a self-regulating integration of artificial & natural systems & intelligence.
•It generally refers to a human who has certain physiological processes aided or controlled by mechanical or electronic devices.
•The term was coined in 1960 when Manfred Clynes & Nathan Kline used it in an article about the advantages of self-regulating human-machine systems in outer space.
Cybernetics is the interdisciplinary study of the structure of complex systems especially communication processes,control mechanisms and feedback principles. It is closely related to control theory and system theory .
• In 1843,Edgar Allan described a man with prostheses in the story ‘The Man That Was Used Up’. • Edmond Hamilton presented space explorers with a mixture of organic & machine parts in his novel ‘The Comet Doom’in 1928 & the talking, living brain of an old scientist,Simon Wright floating around in a transparent case,in adventures of ‘Captain Future.’ • The TV series The Six Million Dollar Man , the Star Wars Terminator series of movies & Star Trek.
• Steve Mann "the world's first cyborg", for his early work with wireless wearable web cams in 1970.

• Claudia Mitchell the first woman outfitted with bionic arm to replace arm she lost in an accident.

• A first incision was made centrally over the median nerve at the wrist and this extended to 4 cm proximally
•A second incision was made 16 c proximal to the wrist, this incision itself extending proximally for 2 cm.
•By means of a tunnelling procedure, the two incisions were connected, ultimately by means of a run of open tubing.
With the array in position, acting as a neural interface, it was possible to
transmit neural signals directly from the peripheral nervous system to acomputer, either by means of a hardwire connection to the terminal pad or through a radio transmitter attached to the pad.

CYBORG PROLIFERATION IN
SOCIETY IN MEDICAL:Two different types of cyborgs :
Restorative technologies “restore lost function, organs, and limbs”.
Enhanced cyborg followsprinciple of optimal performance ie maximising output and minimising input .
Retinal implants are another form of cyborgization to restore vision to people suffering from retinitis pigmentosa and vision loss due to aging and electrical stimulation would act as a substitute for the missing ganglion cells.
IN MEDICAL
IN THE MILITARY
The "cyborg soldier" often refers to a soldier whose weapon and survival systems are integrated into the self, creating a human-machine interface.
Military organizations' research has recently focused on the utilization of cyborg animals for inter-species relationships for the purposes of a supposed a tactical advantage.
DARPA has announced its interest in developing "cyborg insects" to transmit data from sensors implanted into the insect during the pupal stage. The insect's motion would be controlled from a MEMS, or and would conceivably surveil an environment and detect explosives or gas.
Researchers at the University of California, Berkely have set out to "create an exoskeleton that combines a human control system with robotic muscle.“
The device is distinctly Cyborgian in that it is self-powered, and requires no conscious manipulation by
the pilot soldier. The Berkeley Lower Extremity Exoskeleton (BLEEX) helps lighten the load for the human user.
