With the new equipment, scientists are able to take increasingly detailed pictures of the sleeping brain, observing precisely what it is doing while it rests, down to the individual neuron. "In the past year or two, everything seemed to click together," says Dr. Giulio Tononi, a neurobiologist and psychiatrist at the University of Wisconsin at Madison. "Suddenly we have hypotheses that could explain lots of things. Whether they're right is a different story. But I feel different from a few years ago, when the thinking was, 'Who knows?

"When you fall asleep, it's like you're leaving your house and the workmen come in to renovate," suggests Terry Sejnowski, a computational neurobiologist at the Salk Institute in La Jolla, Calif. "You don't want to live in the house while the construction's going on because it's a mess...
...with the neurons. Researchers have discovered that glial cells can also act a lot like the mast cells of the skin, producing inflammatory cytokines that call additional immune cells into action. "The glial cells are trying to return the brain to a normal state," explains Linda Van Eldik, a neurobiologist at Northwestern University Feinberg School of Medicine in Chicago. "But for some reason, in neurodegenerative diseases like Alzheimer's, the process seems to be out of control. You get chronic glial activation, which results in an inflammatory state...
