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.

IS IT REALLY POSSIBLE TO CREATE A HUMAN BRAIN?

Main aim is to upload human brain into machine. Main aim is to upload human brain into machine.

After the death of the body, the virtual brain will After the death of the body, the virtual brain will act as the man.act as the man.

IBM is now in research to create a Virtual Brain.

The first phase of Blue Brain project started after 15 years of systematically dissecting a single neocortical column.

The project has focused not only on building a model of NCC, but on developing a generic facility.

The model of NCC consists of 10,000 3D digitalization of real neurons.

FUNCTIONING OF BRAIN 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 to

perform any action .

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 end of 2006.

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.

HARDWARE AND SOFTWARE REQUIRMENT

A Super computerMemory with a very large storing capacityProcessor 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.

BENEFITS1. 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.

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.

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:

Will 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.

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.

DISADVANTAGES

We become dependent upon the computer .

Others may use technical knowledge against us.

Another fear is found today with respect to human cloning

RESEARCH WORK

IBM developing the “Blue brain”

IBM, in partnership with scientists at IBM, in partnership with scientists at Switzerland’s Ecole Polytechnique Switzerland’s Ecole Polytechnique Federale De Lausanne’s(EPFL) Brain and Federale De Lausanne’s(EPFL) Brain and Mind Institute will begin simulating the Mind Institute will begin simulating the brain’s biological systems.brain’s biological systems.

FUTUREInformation from the molecular and genetic level will be added to the algorithms.

The project will search for insights into how human beings think and remember.

Scientists think that blue brain could also help to cure the Parkinson's disease.

The brain circuitry is in a complex state of flux, the brain rewiring itself every moment of its existence. If the scientists can crack open the secret of how and why the brain does it, the knowledge could lead to new breed of supercomputers.

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.
