Scientists Build An Artificial Brain

Scientists Build An Artificial Brain : Discovery News: "The MIT researchers designed a computer chip that can simulate the activity of a single brain synapse. The synapse is the connection between two neurons, through which information flows. But it isn’t like a wire. Synapses are gaps and chemical signals, in the form of neurotransmitters, jump across them and bind to receptors. Those receptors activate ion channels. When an ion channel is opened and closed it changes the cell’s electrical potential and if the change is large enough, an electrical impulse is fired -- called an action potential."
