2. 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 .“ BLUE BRAIN”- The name of the world’s first virtual brain. That means a machine that can function as human brain.

3. BACKGROUND OF THE STUDY Blue Brain, an Artificial Brain which is an initiative taken by Swiss brain research that aims to recreate an artificial brain by performing reverse engineering on brain circuitry. The Blue brain project was initially founded on May 2005 at Brain and mind institute named EPFL( EcolePolytechnique Federale de Lausanne) in Switzerland that specializes in natural sciences and engineering . Project blue brain is headed by Henry Markram , professor at EPFL. The blue brain is using a supercomputer which was created by IBM called as “Blue Gene” which runs software developed by Michael Hines’s and John Moore named “NEURON”, a simulation environment which models network of neurons in human brain.It’s been said that by 2023 project will be launched officially.

4. ARCHITECTURE IS IT REALLY POSSIBLE TO CREATE A HUMAN BRAIN ?  Main aim is to upload human brain into machine.  After the death of the body, the virtual brain willact as the man.  IBM is now in research to create a Virtual Brain.  The first phase of Blue Brain project started after15 years of systematically dissecting a single neocortical column.  The project has focused not only onbuilding a model of NCC, but ondeveloping a generic facility.  The model of NCC consists of 10,000 3Ddigitalization of real neurons.

5. FUNCTIONING OF 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 top erform any action.

6. Modeling The Blue Brain 1) Modeling the neurons :-  Shape & Structure influences it’s electrical properties .  Neuron morphology & Electrical behavior of the Juvenile Rat is used as the basis for the model. 2) Modeling connections :-  Precise density & Volume of the Cell provides essential information for constructing cortical circuits .  Blue Gene is used in intensive calculation to fix the synapse locations. 3) Modeling the column :-  The result of all these calculations is a recreation at the cellular level of the NCC.  A model of NCC was completed at the endof 2006.

8. NATURAL BRAIN SIMULATED BRAIN INPUT Through the natural neurons. INPUT Through the silicon chip or artificial neurons. INTERPRETATION By different states of the neurons in the brain. INTERPRETATION By a set of bits in the set ofregister OUTPUT Through the natural neurons. OUTPUT Through the silicon chip. PROCESSING Through arithmetic and logical calculations. PROCESSING Through arithmetic and logical calculation and artificial intelligence. MEMORY Through permanent states of neurons. MEMORY Through Secondary memory. BRAIN SIMULATION

9. 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 that is as close as our mind can be 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.

10. HARDWARE AND SOFTWARE REQUIRMENTS  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 .

11. APPLICATIONS OF BLUE BRAIN • Gathering and Testing 100 Years of Data. • Cracking the Neural Code. • Understanding Neocortical Information Processing. • A Novel Tool for Drug Discovery for Brain Disorders. • A Global Facility. • A Foundation for Whole Brain Simulations. • A Foundation for Molecular Modeling of Brain Function.

12. 1) Gathering and testing 100 years of data:  To provide a working model into which the past 100 years knowledge about the microstructure and workings of the neocortical column can be gathered and tested. 2) Cracking the neural code:  The Neural Code refers to how the brain builds objects using electrical patterns.  Creating an accurate replica of the NCC which faithfully reproduces the emergent electrical dynamics of the real microcircuit, is an absolute requirement to revealing how the neocortex processes, stores and retrieves information .

13. 3) Understanding neocortical information processing :  The power of an accurate simulation lies in the predictions that can be generated about the neocortex . Indeed, iterations between simulations and experiments are essential to build an accurate copy of the NCC . 4) A novel tool for drug discovery for brain disorders :  Understanding the functions of different elements and pathways of the NCC will provide a concrete foundation to explore the cellular and synaptic bases of a wide spectrum of neurological and psychiatric diseases . 5) A global facility:  A software replica of a NCC will allow researchers to explore hypotheses of brain function and dysfunction accelerating research.

14. 6) A foundation for whole brain stimulations:  Generate reduced models that retain critical functions and computational capabilities , which can be duplicated and interconnected to form neocortical brain regions . Knowledge of the NCC architecture can be transferred to facilitate reconstruction of subcortical brain regions. 7) A foundation for molecular modeling of brain function: It w ill provide the first and essential step to a gradual increase in model complexity moving towards a molecular level description of the neocortex with biochemical pathways being simulated.

15. ADVANTAGES OF BLUE BRAIN  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 .

16. DISADVANTAGES OF BLUE BRAIN  We become dependent upon the computer .  Others may use technical knowledge against us.  Another fear is found today with respect to human cloning.

17. 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.
