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?
• “YES", 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
• 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.
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.
BLUE BRAIN PROJECT OBJECTIVES
 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.
HARDWARE AND SOFTWARE REQUIRMENT
 A super computer. (Blue Gene/L )
 22.8 TFLOPS peak processing speed.
 Processor with a very high processing power.
 8,096 CPUs at 700 MHz (downgraded to handle massive
parallel processing).
 256MB to 512MB memory per processor with a very large
storing capacity..
 Linux and C++ software.
 100 kilowatts power con
 A very wide network.
 Very powerful Nanobots to act as the interface between
the natural brain and the computer
The Blue Gene/L supercomputer
architecture
STEPS INVOLVED
UPLOADING HUMAN BRAIN:NANOBOTS
• The uploading is possible by the use of small robots
known as the nanobots
• These robots are small enough to travel throughout 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
Modeling the Brain
1:Modeling the neurons: The team will start by modeling the electrical structure of neural
circuits repeated throughout the brain and then map and model their
behavior.
 Shape & Structure influences it’s electrical properties.
 infrared differential interference microscopy allow the
systematic quantification of the molecular, morphological and
electrical properties of the different neurons
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
Once complete, they will move onto creating a molecular
model of the neurons involved and a complete neocortex
(the largest and most complex part of the human brain)
before modelling the rest of the brain
Model of NCC:
BRAIN SIMULATION
 Once the neural microcircuit is built, the exciting work of

making the circuit function can begin.
All the 8192 processors of the Blue Gene are pressed into service,
in a massively parallel computation solving the complex
mathematical equations that govern the electrical activity in
each neuron when a stimulus is applied.
As the electrical impulse travels from neuron to neuron, the
results are communicated via inter-processor communication
(MPI).
Currently, the time required to simulate the circuit is about two
orders of magnitude larger than the actual biological time
simulated.
The Blue Brain team is working to streamline the computation
so that the circuit can function in real time - meaning that 1
second of activity can be modeled in one second
RECONSTRUCTING THE NEOCORTICAL COLUMN
NATURAL BRAIN VS
SIMULATED
BRAIN
EXAMPLE OF BLUE BRAIN
 A very good example of utilization of blue brain is the case
"short term memory".
 Another situation is that when a person gets older, then he
starts forgetting or takes a bit more time to recognize to a
person.
 For the above reason we need a blue brain. It is simple chip
that can be installed into the human brain for which the
short term memory and volatile memory at the old age can
be avoided.
Applications of Blue Brain
 Cracking the Neural Code
 To develop a new breed of supercomputer
 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 Modelling of Brain
Function
Advantages and limitations
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.
