•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.

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.

Blue Gene : Super Computer

•Blue Gene – Computer architecture project

designed to produce several super

computers having speeds in PFLOPS range.•4 Blue Gene Projects

Blue Gene/L Blue Gene/C Blue Gene/P Blue Gene/Q

Blue Gene/L :

•Developed through a partnership with Lawrence

Livermore National Laboratory (LLNL).

•Theoretical performance : 478 TFLOPS sustained

596 TFLOPS peak.

•It uses Lustre to access multiple file systems in the

600TB – 1PB range.

Features:•Trading the speed of processors for low power

consumption

•Duel processors per node with two working modes

•System on-chip design

•Large number of nodes

•3D torus interconnect with auxiliary networks

•Lightweight OS per node for minimum system

overhead

Architecture:

• 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

UPLOADING HUMAN BRAIN

• 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.

BRAIN SIMULATIONBRAIN SIMULATION

•The electrical activity of each neuron is simulated

via supercomputers•A visual exploration of the circuit is an important

part of the analysis•As the electrical impulse travels through the column,

neurons light up and change color as they become

electrically active•All calibrating & comparing fn.s of Blue Brain

BENEFITS

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.

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.

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.

FUTURE• Information 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.

CONCLUSIONCONCLUSION

•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.
