The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Researchers find evidence for precise communication across brain areas during sleep

By listening in on the chatter between neurons in various parts of the brain, researchers from the California Institute of Technology (Caltech) have taken steps toward fully understanding just how memories are formed, transferred, and ultimately stored in the brain--and how that process varies throughout the various stages of sleep.

Brain protein may be a target for fast-acting antidepressants

It takes weeks or months for the effect of most antidepressants to kick in, time that can feel like an eternity to those who need the drugs the most. But new research suggests that a protein called p11, previously shown to play a role in a person's susceptibility to depression, activates a serotonin receptor in the brain known for producing

Study finds risks and benefits of intensive insulin therapy in neurosurgical patients

A study in the March 2009 issue of Anesthesiology found that, in neurosurgical patients receiving postoperative intensive care, intensive insulin therapy - compared to conventional insulin therapy - leads to conflicting results: It increases the risk of hypoglycemic episodes, but reduces the incidence of postoperative infections and the length of stay in the intensive care unit.

Stroke treated significantly faster and just as safely by medical residents

Diagnosing acute stroke is a high-pressure decision. The speed with which treatment is delivered makes all the difference. Early treatment can stop brain damage, but if treatment is given inappropriately, it can dangerously increase the risk of bleeding in the brain.
