ABSTRACT
Human brain is the most valuable creation of God. The man is intelligent because of the brain. “Blue brain” is the name of the
world’s first virtual brain. That means a machine can function as human brain. Today scientists are in research to create an
artificial brain that can think, response, take decision, and keep anything in memory. The main aim is to upload human brain
into machine. So that man can think, take decision without any effort. After the death of the body, the virtual brain will act as
the man .So, even after the death of a person we will not lose the knowledge, intelligence, personalities, feelings and memories
of that man that can be used for the development of the human society.
1. INTRODUCTION
The Blue Brain System is an attempt to reverse engineer the human brain and recreate it at the cellular level inside a
computer simulation. The project was founded in May 2005 by Henry Markram at the EPFL in Lausanne, Switzerland.
Goals of the project are to gain a complete understanding of the brain and to enable better and faster development of
brain disease treatments. The research involves studying slices of living brain tissue using microscopes and patch
clamp electrodes. Data is collected about all the many different neuron types. This data is used to build biologically
realistic models of neurons and networks of neurons in the cerebral cortex. The simulations are carried out on a Blue
Gene supercomputer built by IBM, hence the name "Blue Brain". The simulation software is based on Michael
Hines's NEURON, together with other custom-built components.
As of August 2012 the largest simulations are of micro circuits containing around 100 cortical columns such
simulations involve approximately 1 million neurons and 1 billion synapses. This is about the same scale as that of
a honey bee brain. It is hoped that a rat brain neocortical simulation (~21 million neurons) will be achieved by the end
of 2014. A full human brain simulation (86 billion neurons) should be possible by 2023 provided sufficient funding is
received.
2. WHAT IS BLUE BRAIN?
The IBM is now developing a virtual brain known as the Blue brain. It would be the world’s first virtual brain. Within
30 years, we will be able to scan ourselves into the computers. We can say it as Virtual Brain i.e. an artificial brain,
which is not actually a natural brain, but can act as a brain. It can think like brain, take decisions based on the past
experience, and respond as a natural brain. 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 artificial one. Through this interface the data
stored in the natural brain can be up loaded into the computer. So the brain and the knowledge, intelligence of anyone
can be kept and used for ever, even after the death of the person.
3. NEED OF VIRTUAL BRAIN
Today we are developed because of our intelligence. Intelligence is the inborn quality that cannot be created .Some
people have this quality, so that they can think up to such an extent where other cannot reach. Human society is always
in need of such intelligence and such an intelligent brain to have with. But the intelligence is lost along with the body
after the death. The virtual brain is a solution to it. The brain and intelligence will be alive even after the death. We
often face difficulties in remembering things such as people names, their birthdays, and the spellings of words, proper
grammar, important dates, history facts, and etcetera. In the busy life everyone wants to be relaxed.
Can’t we use any machine to assist for all these? Virtual brain may be a better solution for it. What will happen if we
upload ourselves into computer, we were simply aware of a computer, or maybe, what will happen if we lived in a
computer as a program?
4. HOW IT IS POSSIBLE?
First, it is helpful to describe the basic manners in which a person may be uploaded into a computer. Raymond
Kurzweil recently provided an interesting paper on this topic. In it, he describes both invasive and noninvasive
techniques. The most promising is the use of very small robots, or nanobots. These robots will be small enough to travel
throughout our circulatory systems. 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 computers that is as close as our
mind can be while we still reside in our biological form. Nanobots could also carefully scan the structure of our brain,
providing a complete readout of the connections between each neuron. They would also record the current state of the
brain. This information, when entered into a computer, could then continue to function like us. All that is required is a
computer with large enough storage space and processing power.
5. FUNCTIONING OF HUMAN BRAIN
The human ability to feel, interpret and even see is controlled, in computer like calculations, by the magical nervous
system. Yes, the nervous system is quite like magic because we can’t see it, but its working through electric impulses
through your body. One of the world’s most "intricately organized" electron mechanisms is the nervous system. Not
even engineers have come close for making circuit boards and computers as delicate and precise as the nervous system.
To understand this system, one has to know the three simple functions that it puts into action: sensory input,
integration, motor output.
1. Sensory input:
When our eyes see something or our hands touch a warm surface, the sensory cells, also known as Neurons, send a
message straight to your brain. This action of getting information from your surrounding environment is called sensory
input because we are putting things in your brain by way of your senses.
2. Integration:
Integration is best known as the interpretation of things we have felt, tasted, and touched with our sensory cells, also
known as neurons, into responses that the body recognizes. This process is all accomplished in the brain where many
neurons work together to understand the environment.
3. Motor Output:
Once our brain has interpreted all that we have learned, either by touching, tasting, or using any other sense, then our
brain sends a message through neurons to effecter cells, muscle or gland cells, which actually work to perform our
requests and act upon the environment. How we see, hear, feel, smell, and take decision.
COMPUTER HARDWARE/ SUPERCOMPUTERS
Blue Gene/P
The primary machine used by the Blue Brain Project is a Blue Gene supercomputer built by IBM. This is where the
name "Blue Brain" originates from. IBM agreed in June 2005 to supply EPFL with a Blue Gene/L as a "technology
demonstrator". The IBM press release did not disclose the terms of the deal. In June 2010 this machine was upgraded
to a Blue Gene/P. The machine is installed on the EPFL campus in Lausanne (Google map) and is managed
by CADMOS (Center for Advanced Modeling Science).
The computer is used by a number of different research groups, not exclusively by the Blue Brain Project. In mid-2012
the BBP was consuming about 20% of the compute time. The brain simulations generally run all day, and one day per
week (usually Thursdays). The rest of the week is used to prepare simulations and to analyze the resulting data. The
supercomputer usage statistics and job history are publicly available online - look for the jobs labeled as "C-BPP".
Blue Gene/P technical specifications
4,096 quad-core nodes
Each core is a PowerPC 450, 850 MHz
Total: 56 teraflops, 16 terabytes of memory
4 racks, one row, wired as a 16x16x16 3D torus
1 PB of disk space, GPFS parallel file system
Operating system: Linux SuSE SLES 10
This machine peaked at 99th fastest supercomputer in the world in November 2009.
DEEP - DYNAMICAL EXASCALE ENTRY PLATFORM
DEEP (deep-project.eu) is an exascale supercomputer to be built at the Jülich Research Center in Germany. The project
started in December 2011 and is funded by the European Union's 7th framework program. The three-year prototype
phase of the project has received €8.5 million. A prototype supercomputer that will perform at 100 petaflops is hoped to
be built by the end of 2014. The Blue Brain Project simulations will be ported to the DEEP prototype to help test the
system's performance. If successful, a future exascale version of this machine could provide the 1 exaflops of
performance required for a complete human brain simulation by the 2020s.The DEEP prototype will be built using Intel
MIC (Many Integrated Cores) processors, each of which contains over 50 cores fabricated with a 22 nm process. These
processors were codenamed Knights Corner during development and subsequently rebranded as Xeon Phi in June 2012.
The processors will be publicly available in late 2012 or early 2013 and will offer just over 1 teraflop of performance
each.
9. UPLOADING HUMAN BRAIN
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 computers that is as close as our
mind can be while we still reside in our biological form. Nanobots could also carefully scan the structure of our brain,
providing a complete readout of the connections. 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.
Merits and demerits
With the blue brain project the things can be remembered without any effort, decisions can be made without the
presence of a person. Even after the death of a man his intelligence can be used. The activity of different animals can be
understood. That means by interpretation of the electric impulses from the brain of the animals, their thinking can be
understood easily. It would allow the deaf to hear via direct nerve stimulation, and also be helpful for many
psychological diseases.
Due to blue brain system human beings will become dependent on the computer systems. Technical knowledge may be
misused by hackers; Computer viruses will pose an increasingly critical threat. The real threat, however, is the fear that
people will have of new technologies. That fear may culminate in a large resistance. Clear evidence of this type of fear
is found today with respect to human cloning.
What can we learn from Blue Brain?
Detailed, biologically accurate brain simulations offer the opportunity to answer some fundamental questions about the
brain that cannot be addressed with any current experimental or theoretical approaches. Understanding complexity At
present, detailed, accurate brain simulations are the only approach that could allow us to explain why the brain needs to
use many different ion channels, neurons and synapses, a spectrum of receptors, and complex dendritic and axonal
arborizations.
Applications:
1. Gathering and Testing 100 Years of Data.
2. Cracking the Neural Code
3. Understanding Neocortical Information Processing
4. A Novel Tool for Drug Discovery for Brain Disorders
5. A Global Facility
6. A Foundation for Whole Brain Simulations
7. A Foundation for Molecular Modeling of Brain Function
10. CONCLUSION
In conclusion, we will be able to transfer ourselves into computers at some point. Most arguments against this outcome
are seemingly easy to circumvent. They are either simple minded, or simply require further time for technology to
increase. The only serious threats raised are also overcome as we note the combination of biological and digital
technologies. While the road ahead is long, already researches have been gaining great insights from their model.
Using the Blue Gene supercomputers, up to 100 cortical columns, 1 million neurons, and 1 billion synapses can be
simulated at once. This is roughly equivalent to the brain power of a honey bee. Humans, by contrast, have about 2
million columns in their cortices. Despite the sheer complexity of such an endeavor, it is predicted that the project will
be capable of this by the year 2023.
