This document discusses the Blue Brain project, which aims to create a virtual brain through detailed computer simulation. It is being developed by IBM to function like the human brain by taking inputs, interpreting them, and providing outputs. The simulation involves modeling the electrical activity and behavior of neural circuits. Once complete, the entire neocortex and other brain areas will be modeled. The goal is to eventually be able to upload a person's intelligence and memories into a virtual brain, allowing them to live on digitally. Advantages include improved memory and decision making. Requirements include very powerful computers and nanobots to interface with the natural brain.

3. INTRODUCTION
BLUE BRAIN- The name
of the worlds first virtual brain. That means a
machine that can function as human brain.
4. 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.
5. WHAT IS VIRTUAL BRAIN?
A machine that can function as brain
It can take decision.
It can think.
It can response.
It can keep things in memory.
It also has feelings and emotions.
6. 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 .
7. 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 .
8. BRAIN SIMULATION
NATURAL BRAIN VS SIMULATED BRAIN
INPUT INPUT
Through the natural Through the silicon chip
neurons or artificial neurons
INTERPRETATION INTERPRETATION
By different states of the By a set of bits in the set
neurons in the brain. of register
9. OUTPUT OUTPUT
Based on the states of Output is based on
the neurons , electric registers and sent
impulses are sent. through artificial
neurons.
PROCESSING PROCESSING
Past experience and Decision making is done
current input are used andusing stored states and
states of neurons are input
change
MEMORY MEMORY
Through permanent states Through Secondary
of neurons memory
10. STEPS INVOLVED
The team will start by modeling the electrical
structure of neural circuits repeated throughout
the brain and then map and model their behavior.
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.
12. 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 while we still reside in our biological
form .
13. 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.
14. Simulating the micro circuit
Once the microcircuit is built, 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).
15. 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.
16. HARDWARE AND SOFTWARE REQUIRMENT
22.8 TFLOPS peak processing speed.
8,096 CPUs at 700 MHz (downgraded to handle
massive parallel processing).
256MB to 512MB memory per processor.
Linux and C++ software.
100 kilowatts power consumption.
very powerful Nanobots to act as the interface
between the natural brain and the computer.
