Human Brain- The most important part of the body. Its like
CPU of a computer without which the whole system cannot
Without which we cannot think, percept, feel, act or do anything.
What happens if our brain malfunctions...??
Can we store data of a human brain into memory devices....??
Can we have the benefits of a persons intelligence even after he dies?
Can a person make decisions and attend meetings without being
physically or mentally present there...??
The answer to the above question is
A machine that can function as brain
It can take decision.
It can think.
It can response.
It can keep things in memory.
What is a blue brain??
Blue brain is the name given to the virtual human brain.
It would be the worlds first virtual human brain.
Within next 30 years we will be able to scan or brains into
our computers including:
The Blue Brain Project is an attempt to reverse engineer the human brain and
recreate it at the cellular level inside a computer simulation.
>> Studying slices of living brain tissue using highly accurate apparatus.
>> Collecting data about different neurons
>> Data collected is used to build biological realistic model
>> This data is then simulated into artificial neuronal network by a supercomputer.
The Blue Brain Project(cont.)
The simulations are carried out on a Blue Gene supercomputer built by IBM

How the Blue brain will work…???
How the human brain will be uploaded
into it …???
Possible due to the fast growing
Nanobots could 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.
Objectives of blue brain project
1) The project will search for insights into how human beings
think and remember.
2) Scientists think that blue brain could also help to cure many
brain diseases including the well known Parkinson disease.
3) 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.
A very good example of utilization of blue brain is the case
"short term memory
We can implant a micro chip into brain to act as secondary
One of the most important aspect of blue brain project is that we
can retain memory and intelligence even after a person dies.
Hardware for Data Acquisition
A patch-clamp microelectrode is a
micropipette with a relatively large
tip diameter. The microelectrode is
placed next to a cell, and gentle
suction is applied through the
microelectrode to draw a piece of the
cell membrane (the 'patch') into the
microelectrode tip; the glass tip
forms a high resistance 'seal' with the
The part of cell is then studied under
Patch Clamp Electrode
A Super computer
2) Memory with a very large storing capacity.
3) Processor with a very high processing power.
4) A program to convert the electric impulses from the brain to input signal, which
is to be received by the computer and vice versa.

The primary software used by
the BBP for neural simulations is
a package called NEURON.It is
written in C, C++, and
2. “RTNeuron” Software for visualisation
RTNeuron is the primary
application used for
visualisation of neural
simulations.It is written
in C++ and
specifically for neural
takes the output
simulations in NEURON
and renders them in 3D.
Remembering things without any effort.
Making decision without the presence of a person.
Using intelligence of a person after the death .
Curing various brain disease as we could study
We may become dependent upon the computer for making
Others may use technical knowledge against us.
