INTRODUCTION
In 2009, neuroscientist Henry Markram publicly announced that he seeks to reverse-engineer a human brain with digital simulations of all the physical properties of every neuron, powered by IBM Blue Gene supercomputers, by 2020.

WHAT IS BLUE BRAIN?
• First virtual brain• Human brain as computer simulation• Think, response, take decision, and keep
anything in memory

Building virtual brain
1. Data acquisition2. Simulation3. Visualization of results

DATA ACQUISITION
• Measurement of shapes and electrical activity of neurons
• Translation into mathematical algorithms
• Generation of biologically-realistic virtual neurons

SIMULATION• NEURON• Written in C, C++, and FORTRAN
![Page 8: Bluebrain](https://reader035.vdocuments.us/reader035/viewer/2022070313/5549c035b4c905bc6d8b529e/html5/thumbnails/8.jpg)
SIMULATION
• Synthesizing virtual cells
• Simulation if every single protein
• Building network skeleton

VIRTUALIZATION• RTNeuron• Written in C++ and OpenGL• Takes the output simulations in NEURON and
renders them in 3D

Brain Simulation
Natural Brain Simulated Brain
Input Through the natural neurons
Through the silicon chip or artificial neurons
Interpretation By different states of the neurons in the brain
By a set of bits in the set of register

How to gather information?
• Nanobots• Monitoring activity & structure of CNS
![Page 13: Bluebrain](https://reader035.vdocuments.us/reader035/viewer/2022070313/5549c035b4c905bc6d8b529e/html5/thumbnails/13.jpg)
Success
• Successful simulation of rat cortical column
• Generation of brain’s building blocks • 100 cortical columns made by Aug 2012
