Such a column is about 2 mm tall, has a diameter of 0.5
  4. 4. mm and containsabout 60,000neurons inhumans; ratneocortical columnsare very similar instructure butcontain only10,000 neurons(and 108synapses).Between 1995 and2005, Markrammapped the typesof neurons andtheir connections insuch a column.Whole brainsimulationA longer term goalis to build adetailed, functionalsimulation of thephysiologicalprocesses in thehuman brain: "It isnot impossible tobuild a humanbrain and we cando it in 10 years,"Henry Markram,director of the BlueBrain Project saidin 2009 at theTED conference inOxford.[4] In aBBC World Serviceinterview he said:"If we build itcorrectly it shouldspeak and have anintelligence andbehave very muchas a humandoes."[4]Progress
  5. 5. In November2007,[5] theproject reportedthe end of the firstphase, delivering adata-drivenprocess forcreating,validating, andresearching theneocortical column.By 2005 the firstsingle cellularmodel wascompleted. Thefirst artificialcellular neocorticalcolumn of 10,000cells was built by2008. By July 2011a cellularmesocircuit of 100neocortical columnswith a million cellsin total was built. Acellular rat brain isplanned for 2014with 100mesocircuitstotalling a hundredmillion cells. Finallya cellular humanbrain is predictedpossible by 2023equivalent to 1000rat brains with atotal of a hundredbillion cells.[6][7]Now that thecolumn is finished,the project iscurrently busyingitself with thepublishing of initialresults in scientificliterature, andpursuing twoseparate goals:
  6. 6. 1. construction of asimulation on themolecular level,[1]which is desirablesince it allowsstudying the effectsof geneexpression;2. simplification ofthe columnsimulation to allowfor parallelsimulation of largenumbers ofconnectedcolumns, with theultimate goal ofsimulating a wholeneocortex (which inhumans consists ofabout 1 millioncortical columns).FundingThe project isfunded primarily bythe Swissgovernment andsecondarily bygrants and somedonations fromprivate individuals.The EPFL boughtthe Blue Genecomputer at areduced costbecause at thatstage it was still aprototype and IBMwas interested inexploring howdifferentapplications wouldperform on themachine. BBP wasa kind of betatester.[8]
  7. 7. The project is a candidate for a Future and Emerging Technologies (FET) research grant from the European Commission. The grant would bring in €1 billion over 10 years. The final decision on the grant is expected in the second half of 2012. If the grant is awarded, the project will be renamed the Human Brain Project.[9] seminar ideasSuper Moderator RE: blue brain blue brain Blue Brain .docx (Size: 324.88 KB / Downloads: 22) INTRODUCTION Human brain is the
  8. 8. most valuable creationof God. The man iscalled intelligentbecause of the brain.The brain translates theinformation deliveredby the impulses, whichthen enables theperson to react. But weloss the knowledge of abrain when the body isdestroyed after thedeath of man. Thatknowledge might havebeen used for thedevelopment ofthe human society. Inthis technology wecreate a brain and upload the contents ofnatural brain into it.Blue BrainBlue Brain is the nameof the world’s firstvirtual brain. Thatmeans a machine thatcan function as humanbrain. Today scientistsare in research tocreate an artificial brainthat can think, respond,take decision, and keepanything in memory.The main aim is toupload human braininto machine so thatman can think, takedecision without anyeffort. After the deathof the body, the virtualbrain will act as theman. So, even after thedeath of a person wewill not lose theknowledge,intelligence,

If possible, thiswould be the firstvirtual brain of theworld. With in 30 years,we will be able to scanourselves into thecomputers.What is VirtualBrain?Virtual brain is anartificial brain, which isnot actually the naturalbrain, but can act asthe brain. It can thinklike brain, takedecisions based on thepast experience, andrespond as the naturalbrain can. It is possibleby using a supercomputer, with a hugeamount of storagecapacity, processingpower and an interfacebetween the humanbrain and this artificialone. Through thisinterface the datastored in the naturalbrain can be up loadedinto the computer. Sothe brain and theknowledge, intelligenceof anyone can be keptand used for ever, evenafter the death of theperson.
  10. 10. Why we need VirtualBrain?Today we aredeveloped because ofour intelligence.Intelligence is theinborn quality that cannot be created. Somepeople have thisquality, so that theycan think up to such anextent where othercannot reach. Humansociety is always inneed of suchintelligence and suchan intelligent brain tohave with. But theintelligence is lost alongwith the body after thedeath. The virtual brainis a solution to it. Thebrain and intelligencewill be alive even afterthe death.How it is possible?First, it is helpful todescribe the basicmanners in which aperson may beuploaded into acomputer. RaymondKurzweil recentlyprovided an interestingpaper on this topic. Init, he describes bothinvasive andnoninvasive techniques.The most promising isthe use of very smallrobots, or nanobots.These robots will besmall enough to travelthroughoutour circulatory systems.
  11. 11. Travelling into thespine and brain, theywill be ableto monitor the activityand structure of ourcentral nervous system.They will be able toprovide an interfacewith computers that isas close as our mindcan be while we stillreside in our biologicalform. Nanobots couldalso carefully scan thestructure of our brain,providing a completereadout of theconnections betweeneach neuron. Theywould also record thecurrent state of thebrain. This information,when entered into acomputer, could thencontinue to function asus. All that is requiredis a computer withlarge enough storagespace and processingpower. Note, however,that we need not knowhow the brain actuallyfunctions, to transfer itto a computer. For thiswe have to first knowhow the human brainactually works.WORKING OFNATURAL BRAINGetting to knowmore about HumanBrainThe brain essentiallyserves as the body’sinformation processing

It receivessignals from sensoryneurons (nerve cellbodies and their axonsand dendrites) in thecentral and peripheralnervous systems, andin response itgenerates and sendsnew signals thatinstruct thecorresponding parts ofthe body to move orreact in some way. Italso integrates signalsreceived from the bodywith signals fromadjacent areas of thebrain, giving rise toperception andconsciousness. Thebrain weighs about1,500 grams (3pounds) andconstitutes about 2percent of total bodyweight. It consists ofthree major divisions;• The massive pairedhemispheres of thecerebrum• The brainstem,consisting of thethalamus,hypothalamus,epithalamus, subtha-lamus, midbrain, andmedulla oblongata• The cerebellum.The human ability tofeel, interpret and evensee is controlled, incomputer likecalculations, by themagical nervoussystem.

Not even engineers have come close to 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. 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.Reference:
