Blue Brain Essay Example for Free

Blue Brain Essay Today scientists are in research to create an arti? cial brain that can think,respond, take decision, and keep anything in memory. The main aim is to uploadhuman 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 thedeath of a person we will not loose the knowledge, intelligence, personalities, feelingsand memories of that man, that can be used for the development of the human society. Technology is growing faster than every thing. IBM is now in research to create avirtual brain, called â€Å"Blue brain†. If possible, this would be the ? rst virtual brainof the world. IBM, in partnership with scientists at Switzerland’s Ecole Polytech-nique Federale de Lausanne’s (EPFL) Brain and Mind Institute will begin simulatingthe brain’s biological systems and output the data as a working 3-dimensional modelthat will recreate the high-speed electro-chemical interactions that take place withinthe brain’s interior. These include cognitive functions such as language, learning,perception and memory in addition to brain malfunction such as psychiatric disorderslike depression and autism. From there, the modeling will expand to other regions of the brain and, if successful, shed light on the relationships between genetic, molecularand cognitive functions of the brain. The human brain has 100 billion neurons, nerve cells that enable us to adapt quickly to an immense array of stimuli. We use them to understand and respond to bright sunlight, a honking horn, the smell of chicken frying and anything else our sensors detect. To better understand some of those responses, researchers in Lausanne, Switzerland, recently launched an ambitious project called Blue Brain, which uses IBMs eServer Blue Gene, a supercomputer capable of processing 22. 8 trillion floating point operations per second (TFLOPS). Blue Brain is modeling the behavior of 10,000 highly complex neurons in rats neocortical columns (NCC), which are very similar to the NCCs in a human brain. The NCCs run throughout the brains gray matter and perform advanced computing. They are 0. 5mm in diameter and 2mm to 5mm in height and are arranged like the cells of a honeycomb. The first objective of Blue Brain is to build an accurate software replica, or template, of an NCC within two to three years, says Henry Markram, the principal researcher on Blue Brain and a professor at Ecole Polytechnique Federale de Lausanne (EPFL). That first template will be modified for NCCs found in different brain regions and species, and then all the NCCs will be replicated to build a model of the neocortices of different species, he says. Such models will shed light on how memories are stored and retrieved, Markram says. This could reveal many exciting aspects of the [brain] circuits, such as the form of memories, memory capacity and how memories are lost. The modeling can help find vulnerabilities in the neocortex, which is useful because thats where brain disorders often originate. We may also be able to work out the best way to compensate and repair circuit errors, Markram says. The model could be used to develop and test treatment strategies for neurological and psychiatric diseases, such as autism, schizophrenia and depression, he adds. Having an accurate computer-based model of the brain would mean that some major brain experiments could be done in silicon rather than in a wet lab. A simulation that might take seconds on the supercomputer could replace a full days worth of lab research, Markram estimates. Ultimately, simulated results of brain activity could be matched with recorded brain activity in a person with a disease in order to reverse-engineer the circuit changes in diseases, he says. The real value of a simulation is that researchers can have access to data for every single neuron, adds IBMs Charles Peck, head of the Blue Brain project for IBM Research.
