*The brain performs much faster

1. Introduction *The brain is a highly complex, nonlinear, and parallel computer (information processing system). *The brain performs much faster computations (e.g., pattern recognition, perception, motor control) than the fastest digital computer in existence today. * B rain is a neural network, is that every computation performed by the brain is a collective computation . *A neural network is a machine that is designed to model the way in which the brain performs a particular task of function of interest. *Neural networks employ a massive interconnections of Simple computing cells referred to as neurons. * The idea of connecting the human brain to a computer or machine directly is not novel and its potential has been explored in science fiction. With the rapid advances in the areas of information technology, miniaturization and neurosciences there has been a surge of interest in turning fiction into reality.
