INTRODUCTION
 Human brain, the most valuable creation of God.The man is called intelligent because of the Brain.But we loss the knowledge of a brain when the body is destroyed after the death .
 Is it really possible to create a human brain?
WHAT IS BLUE BRAIN
 The name of the world’s first virtual brain. That means a machine that can function as human brain.
 The IBM is now developing the BLUE BRAIN.
 It would be the worlds first virtual brain.Within 30 years, we will be able to scan ourselves into the computers!
BLUE BRAIN
WHY WE NEED VIRTUAL BRAIN
 To understand the human brain
 To keep the intelligence , knowledge and skill of any person for ever .
 Find a remedy to treat mental disorders
 WHAT IS VIRTUAL BRAIN
 A machine that can function as brain .
 It can take decision.
 It can think.
 It can respond.
 It can keep things in memory.
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 .
 PERCEPTIVE BUBBLE
 Brain creates builds a version of the universe
 Projects this version of universe like a bubble
 HOW BIG IS MOON?
 We compare the buildings with in our perceptual bubble
 Make a DECISION is that big even though it is not
DECISIONS
 BRAIN SIMULATION
NATURAL BRAIN VS SIMULATED BRAIN
 INPUT
 Through the natural neurons.
 INPUT
 Through the silicon chip or artificial neurons.
 INTERPRETATION
 By different states of the neurons in the brain
 INTERPRETATION
 By a set of bits in the set of register .
BRAIN SIMULATION
NATURAL BRAIN VS SIMULATED 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 .
 BRAIN SIMULATION
NATURAL BRAIN VS SIMULATED BRAIN
 MEMORY
 Through permanent states of neurons .
 MEMORY
 Through Secondary memory
 Now there is no question how the virtual brain will work. But the question is how the human brain will be up loaded into it. This is also possible due to the fast growing technology.
UPLOADING HUMAN BRAIN
UPLOADING -NANOBOTS
 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 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 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.
HOW THE BLUE BRAIN PROJECT WILL WORK
NEOCORTEX
 The neocortex is the largest and most complex part of the human brain, and constitutes about 85 per cent of the brain's total mass.
 The neocortex is thought to be responsible for the cognitive functions of language, learning, memory and complex thought.
 The simulated neurons will be interconnected with rules the team has worked out about how the brain functions.
NEOCORTICAL COLUMN
 The basic building block of the cortex
 Grand piano
 Morphological Classes of Neocortical Neurons
BRAIN CIRCUIT
 Neurons communicate through synapses
 Synapses are chemical locations
 Synapses together form a network,the circuit of the brain
HARDWARE AND SOFTWARE REQUIRMENT
 A Super computer.
 Memory with a very large storing capacity.
 Processor with a very high processing power.
 A very wide network.
 A program to convert the electric impulses from the brain to input signal, which is to be received by the computer and vice versa.
 Very powerful Nanobots to act as the interface between the natural brain and the computer.
 The Blue Brain has some 8,000 processors which map one or two simulated brain neurons to each processor, making the computer a replica of 10,000 neurons.
BLUE BRAIN MODEL VISUALISATION
 A visual representation of a mammalian neocortical column.
 The representation shows the part of the brain which has been modeled using a supercomputer.
 The visualization is part of an ambitious project to create a biologically accurate, functional model of the brain using IBM's Blue Gene supercomputer.
