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?

WHAT IS BLUE BRAIN
 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.

WHAT IS VIRTUAL BRAIN
 A machine that can function as brain .
 It can take decision.
 It can think.
 It can respond.
 It can keep things in memory.

WHY WE NEED VIRTUAL BRAIN
 To upload contents of the natural brain
into it .
 To keep the intelligence , knowledge and
skill of any person for ever .
 To remember things without any effort .

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 .

BRAIN SIMULATION
NATURAL BRAIN VS SIMULATED BRAIN
 INPUT
 Through the natural
neurons.
 INPUT
 Through the silicon
chip or artificial
neurons.
 INTERPRETATION
 By a set of bits in the
set of register .
 INTERPRETATION
 By different states of
the neurons in the
brain.

 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 .
BRAIN SIMULATION

BRAIN SIMULATION
 MEMORY
 Through permanent
states of neurons .
 MEMORY
 Through Secondary
memory
 Now there is no question how the virtual
brain will work. But the question is how
the human brain will be up loaded into it.
This is also possible due to the fast
growing technology.

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 .

UPLOADING HUMAN
BRAIN(CONT….)
 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.

EXAMPLE OF BLUE BRAIN
 A very good example of utilisation of blue brain is the case
"short term memory".
 In some movies we might have noticed that a person might
be having short term memories.
 A another situation is that when a person gets older, then
he starts forgetting or takes a bit more time to recognise to
a person.
 For the above reason we need a blue brain.It ia 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.

HARDWARE AND SOFTWARE
REQUIRMENT
 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.
 The Blue Brain has some 8,000 processors which map one
or two simulated brain neurons to each processor, making
the computer a replica of 10,000 neurons.

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.

HOW THE BLUE BRAIN
PROJECT WILL WORK
 The neocortex is the largest and most complex part of the
human brain, and constitutes about 85 per cent of the
brain's total mass.
 The neocortex is thought to be responsible for the cognitive
functions of language, learning, memory and complex
thought.
 The simulated neurons will be interconnected with rules the
team has worked out about how the brain functions.
 This result would develop a simulated model known as
“Bluebrain”.

The "Blue Brain" & Human
Consciousness
 "Blue Brain" offer a better understanding of
human consciousness.
 It’s an actual ‘computer brain’ that may
eventually have the ability to think for itself.
 When it was first fed electrical impulses, strange
patterns began to appear with lightning-like
flashes produced by ‘cells’ that the scientists
recognized from living human and animal
processes. "It happened entirely on its own,"

The "Blue Brain" & Human
Consciousness(CONT..)
 This helped the scientists to understand the
actual processing of the brain which arised the
concept of “Blue brain”.
 Blue brain acts as a computer that would operate
at inconceivable speeds – something fast enough
to simulate the human brain.
 A Blue brain aims to unlock the secrets of brain
by using the brute power of a supercomputer.

FLASHES OF ACTIVITY
 Blue Brain started
producing flashes
of activity that
scientists
recognized from
measurements of
natural brain
behavior -- on its
very first day. "It
happened entirely
on its own“.

BLUE BRAIN POWER
 The human brain has 100 billions,nerve cells that
enable us to adapt quickly to an immense array
of stimuli.
 Blue brain is a technology that uses “Blue Gene”
a supercomputer capable of processing 228
TFLOPS.
 The main aim of blue brain is to build an software
replica or template which could reveal many
exisiting aspects of the brain circuits,memory
capacity,and how memories are lost.

BLUE BRAIN POWER(CONT…)
 The modeling is also able to work out best
way to compensate and repair error
circuits .
 The blue brain model can be used to
detect and test treatment statergies for
neurological diseases.

EXPERIMENTS ON BLUE BRAIN
 Scientists rely on computer models to
understand the toughest concepts in
science.
 A computer model is being designed to
take on the human brain.
 A generic template is build which allows
us to reconstruct a brain according to any
specifications.

'Blue Brain': An Artificial Brain
Comes To Life In Switzerland
 The machine is beautiful as it wakes up – it
means it works in a fine way when started.Nerve
cells flicker on the screen , along with that
electrical charges are produced.
 This piece of hardware consists of about 10,000
computer chips that act like real nerve cells.
 The simulation was created at the Technical
University in Lausanne, Switzerland, where 35
researchers participate in maintaining this
artificial brain.

'Blue Brain': An Artificial Brain
Comes To Life In Switzerland
 It runs on one of the world's most
powerful supercomputers.
 The goal is to build a much bigger
electronic thinking machine -- one that
would ultimately replicate the human
brain .
 "Blue Brain," is the most radical attempt
so far to investigate the mystery of
consciousness.

BLUE BRAIN IN
LAUSANNA,SWITZERLAND
 The "Blue Brain" supercomputer in
Lausanne, Switzerland.

BLUE BRAIN MODEL
VISUALISATION
 A visual representation of
a mammalian neocortical
column.
 The basic building block
of the cortex.
 The representation shows
the part of the brain
which has been modeled
using a supercomputer.
 The visualization is part
of an ambitious project
to create a biologically
accurate, functional
model of the brain using
IBM's Blue Gene
supercomputer.

RIDDLE OF CONSCIOUSNESS
 A human brain
consists of 100
billion nerve cells.
A supercomputer
simulating an
organ using
current technology
- would produce a
virtual human
brain.

BLUE BRAIN SIMULATION USING
MICROPROCESSOR
 The Blue Brain
simulation uses one
microprocessor for
each of the 10,000
neurons in the
cortical column of a
rat's cerebral cortex.
It helps to build a
brain microcircuit, in
order to scale it in
human brain.

BENEFITS OF BLUE BRAIN
 It acts as a supercomputer.
 Improvements in processing,speed and memory
could make entire human brain simulated.
 Things could be remembered without any effort.
 Use the intelligence of the person after death.
 It can make decisions entirely of its own.
 Allowing the deaf to hear via direct nerve
simulation.

DISADVANTAGES OF BLUE
BRAIN
 We become dependent upon the
computers.
 Another fear is found with respect to
human cloning.
 A very costly procedure of regaining the
memory back.

CONCLUSION
 Will be able to transfer ourselves into the
computer at some point.
 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.
