New computer simulation may solve questions about human brain function
Playfully leaning back in his chair while sitting in his modest, dimly lit office, molecular biology professor John Hopfield talks about his creation with all the enthusiasm of a proud parent.Hopfield's work area does not seem like the kind of place where the finishing touches would be made to an artificial organism, but that is exactly what he and Carlos Brody, a postdoctoral fellow at the Center for Neural Science at New York University, have done.And last week, they introduced the world to their virtual creation ? the sand mouse, or mus silicium.For this project, Hopfield and Brody created a computer simulation of 660 artificial cells that behave exactly like real brain cells.
