  3. 3. Introduction Human Brain- The most important part of the body. Its like CPU of a computer without which the whole system cannot work. 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 ”BLUE BRAIN”
  4. 4. A machine that can function as brain It can take decision. It can think. It can response. It can keep things in memory.
  5. 5. 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: >Intelligence >Memory >Imaginations >Thoughts >Everything BBP Next->
  6. 6. The Blue Brain Project is an attempt to reverse engineer the human brain and recreate it at the cellular level inside a computer simulation. This includes: >> 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.
  7. 7. The Blue Brain Project(cont.) The simulations are carried out on a Blue Gene supercomputer built by IBM Blue Gene Super Computer, IBM

  11. 11. Neocortex of brain showing neurons in neocortical column.
  12. 12. Brain continuously forms networks among these cells
  13. 13. Huge neuronal network, Neurons uses electrical and chemical signals to communicate
  14. 14.  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 .
  15. 15. Natural brain Vs Simulated Brain INPUT Through the silicon chip or artificial neurons INTERPRETATION By a set of bits in the set of register
  16. 16. Natural brain Vs Virtual 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  MEMORY Through Secondary memory MEMORY Through permanent states of neurons
  17. 17. ??? How the Blue brain will work…??? How the human brain will be uploaded into it …??? Possible due to the fast growing technology.
  18. 18. NANOTECHNOLOGY 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.
  19. 19. WHY BLUE BRAIN?
  21. 21. 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.
  22. 22. 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 memory.
  23. 23. One of the most important aspect of blue brain project is that we can retain memory and intelligence even after a person dies.
  25. 25. 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 cell membrane. The part of cell is then studied under microscope. Patch Clamp Electrode
  26. 26. 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. Technical specification of Blue Gene computer: >> 4,096 quad-core nodes (16,384 cores in total) (850 MHz each) >> 16 terabytes of memory >> Operating system: Linux SuSE SLES 10 >> Hourly process log >> Full-HD passive stereo display connected to two GPUs on head node
  27. 27. Each core is associated with a dedicated 64bit double FPU. Blue gene super computer can work with an efficiency of 8 floating point operation per cycle. The peak performance of Blue Gene super computer is 5.6 billion FLOPS. Graphical processing capacity: >> It’s equipped with 32 processor SGI system having 300 GB of memory. Nanobots Very powerful Nanobots to act as the interface between the natural brain and the computer.
  28. 28. Software Requirements 1. “NEURON” SOFTWARE The primary software used by the BBP for neural simulations is a package called NEURON.It is written in C, C++, and FORTRAN.
  29. 29. 2. “RTNeuron” Software for visualisation RTNeuron is the primary application used for visualisation of neural simulations.It is written in C++ and OpenGL.RTNeuron is software written specifically for neural simulations. RTNeuron takes the output simulations in NEURON and renders them in 3D.
  30. 30. Hardware requirements of Rtneuron Software: >> 11 node cluster, 3.47 GHz processors (Intel Xeon X5690) >> 24 GB RAM, 3 Nvidia GeForce GTX 580 GPUs >> Full-HD passive stereo display connected to two GPUs >> 1 Gbit/s, 10 Gbit/s ethernet, 40 Gbit/s QDR InfiniBand
  31. 31. ADVANTAGES  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 them properly.
  32. 32.  We may become dependent upon the computer for making decisions.  Others may use technical knowledge against us. Another fear is found with respect to human cloning.
