What makes people smart? It is a question that scientists and philosophers have pondered for centuries, prompting complex calibrations, from head measurements to brain-bending tests. Yet the drive to probe the powers--and the limits--of the human mind has been thwarted by the hard facts of life: The brain was virtually a black box, its inner secrets locked within. Now, scientists are using the latest technology to peer inside.

Dr. Gerald Maguire's interest in stuttering dates back to the time he was a toddler, when he first tried to string sentences together. Through the years, as listeners pleaded with him to "just relax," he struggled to speak with the same fluency as those around him, always believing that it was a matter of psychic strength, of trying harder to force out the words trapped inside. His research is proving him wrong.

Photographer Bob East lay in a coma Tuesday, apparently brain dead after doctors accidentally injected a toxic preservative into his spine in what the head surgeon called "a tragic series of human errors." The substance, glutaraldehyde, was mistaken for spinal fluid taken from the patient earlier during an operation to remove a cancerous eye, said the surgeon, Dr. James Ryan Chandler. East underwent the operation last Friday and was found to be brain dead Monday.

New research adds hope that epileptics could one day wear tiny brain sensors that detect an impending seizure and release medicine from implanted pumps in time to avert an attack. In most epileptics, seizures occur without warning and can sometimes be disabling or fatal. Now, French scientists have developed a way to use electrodes on the scalp that can sense changes in brain activity an average of seven minutes before seizures occur. "This is far in the future. This is only a step," said Dr.

A Mexicali man who was struck in the head by a bullet fired from a passing car in Santa Ana Sunday was breathing Monday on a mechanical support system at Fountain Valley Regional Hospital, hospital officials said, but his brain-wave activity has ceased. Ralph Moore, 20, was still listed in critical condition, a hospital spokeswoman said.

Standard doses of the sex hormone estrogen strengthen brain activity in older, post-menopausal women, Yale University researchers said Tuesday, offering the best evidence yet that the commonly prescribed hormone alters the neural circuits involved in human memory. By testing the kind of working memory involved in everyday verbal and visual tasks, the researchers quickly detected significant differences in neural activity between women who were taking the hormone and those who were not.

California researchers have found a new clue to the cause of narcolepsy, a neurological disorder characterized by intense sleepiness and episodes of cataplexy--an abrupt loss of muscle tone that is often triggered by sudden strong emotions. They have found that cataplexy is caused by the same brain cells that cause loss of muscle tone during so-called "rapid-eye-movement," or REM, sleep. Narcolepsy affects an estimated one in 2,000 people in the United States, a total of more than 125,000.

Picture music history in the shape of the human body, and then we can argue about who is what. I would make Mozart the heart; the ever pushy Beethoven, the hands; Wagner, the mouth telling everyone what to think (or maybe the genitals); and John Cage would be the left foot placed far forward, ahead of everyone else and poised to trip the whole contraption. You may have other ideas. But would anyone deny that Bach is the brain?

A research team has managed to crack the mind's internal code and deduce what a person is looking at based solely on brain activity, a feat that could pave the way for what the scientists described as "a brain-reading device." The ability to read minds reliably is still beyond the grasp of science, but the study published last month by neuroscientists at UC Berkeley builds on a growing body of work on how to hack into the brain's inner language. The Berkeley team, which published its study online in the journal Nature, used a brain scan to find patterns of activity when people looked at black-and-white images of ordinary items such as bales of hay, a starfish or a sports car. When the people then looked at different photos, a software program drew on activity in the brain's vision center to guess which images they saw with, up to 92% accuracy.

With his family claiming he was improving, Irv Rubin remained in grave condition Tuesday as new details emerged about what authorities called his suicide attempt in federal prison. The firebrand national director of the Jewish Defense League suffered serious head injuries Monday when, according to officials, he slashed himself with a razor, then leaped over a railing at the Metropolitan Detention Center in downtown Los Angeles.
