INTRODUCTION Human brain, the most valuable creation of God. The man is called intelligent because of the brain But we loss the knowledge of a brain when the body is destroyed after the death of man. That knowledge might have been used for the development of the human society. Is it really possible to create a human brain?
³YES", The IBM is now developing a virtual brain known as the BLUE BRAIN. It would be the worlds first virtual brain. Within 30 years, we will be able to scan ourselves into the computers.
BLUE BRAIN ³Blue brain´ ±The name of the world¶s first virtual brain. That means a machine that can function as human brain. Today ,scientists are in research to create an artificial brain that can think, response, take decision, and keep anything in memory. The main aim is to upload human brain into machine. So that man can think, take decision without any effort. After the death of the body, the virtual brain will act as the man .
So, even after the death of a person we will not loose the knowledge, intelligence, personalities, feelings and memories of that man that can be used for the development of the human society. IBM is now in research to create a virtual brain. It is called ³Blue brain ³. If possible, this would be the first virtual brain of the world.
VIRTUAL BRAIN Virtual brain is an artificial brain, which does not actually the natural brain, but can act as the brain. It can think like brain, take decisions based on the past experience, and response as the natural brain can. It is possible by using a super computer, with a huge amount of storage capacity, processing power and an interface between the human brain and this artificial one . Through this interface the data stored in the natural brain can be uploaded into the computer .
Why we need VIRTUAL BRAIN ? Intelligence ,Knowledge and skill of a person can be made eternal. We can upload the contents of natural brain into it. Things can be made easy as everything is automated.
Function of a Brain Sensory Input :- Receiving input such as sound ,image, etc through sensory cell . Interpretation:- Interpretation of the received input by the brain by defining states of neurons in the brain. Motor Output:- Receiving of electric responses from the brain to perform any action .
BRAIN SIMULATIONNATURAL BRAIN SIMULATED BRAIN INPUT Through the silicon chip or Through artificial neurons INTERPRETATION By a set of bits in the set of register
NATURAL BRAIN SIMULATED BRAINOUTPUT OUTPUT Through the natural neurons. Through the silicon chip. PROCESSING PROCESSING Through arithmetic and Through arithmetic andlogical calculations logical calculation and artificial intelligenceMEMORY MEMORY Through permanent states of Through Secondary memoryneurons
HARDWARE AND SOFTWARE REQUIREMENTS A super computer. Memory with a very large storing capacity. Processor with a very high processing power. A very wide network. A program to convert the electric impulses from the brain to input signal, which is to be received by the computer, and vice versa. Very powerful Nanobots to act as the interface between the natural brain and the computer
Uploading Human Brain The uploading is possible by the use of small robots known as the nanobots. These robots are small enough to travel through out our circulatory system. Traveling into the spine and brain, they will be able to monitor the activity and structure of our central nervous system. They will be able to provide an interface with computer while we still reside in our biological form .
Nanobots could also carefully scan the structure of our brain, providing a complete readout of the connection. This information, when entered into a computer, could then continue to function as us. Thus the data stored in the entire brain will be uploaded into the computer.
CURRENT RESEARCH WORK IBM developing the ³Blue brain´ . IBM, in partnership with scientists at Switzerland¶s Ecole Polytechnique Federal De Lausanne¶s(EPFL) Brain and Mind Institute will begin simulating the brain¶s biological systems.
Researchers at Micr s fts Media resence Lab are developing a "virtual brain," a -based database that holds a record of an individuals co plete life experience. "By 2047, al ost all information ill be in cyberspace including all knowledge and creative works, said one of the projects leaders, ordon Bell.
ADVANTAGES Remembering things without any effort. Making decision without the presence of a person. Using intelligence of a person after the death . Understanding the activities of animals . Allowing the deaf to hear via direct nerve stimulation.
DISADVANTAGESy We become dependent upon the computer .y Others may use technical knowledge against us.y Another fear is found with respect to human cloning.y A very costly procedure of regaining the memory back.
CONCLUSION We will be able to transfer ourselves into computers at some point. It will bring both benefits and harm to human society . Eventually aim of applying terrific computer power to the simulation of an entire brain. Very soon this technology will be highly accepted whole over the world.
