...recording of the waves of electrical activity in the brain--with far more sophisticated imaging and neurological mapping techniques. 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...
Released last Thursday in the journal Neuron, the article indicates that certain people may have a genetic predisposition toward cocaine addiction, raising important public policy issues and ethical questions about the nature of addiction...
...instance, you could wipe out all of the neurotransmitter secretory vesicles in a part of a neuron, and then watch how new vesicles are made and trafficked to the site of secretion,” said David W. Piston, professor of molecular physiology and biophysics at Vanderbilt University...
...raising big questions about the safety of human mobile-phone use. In a paper that will be published in April by the U.S. journal of the National Institute of Environmental Health Sciences, Salford's research team suggests that even tiny levels of radiation from standard European mobiles may cause neuron damage in the brain. Since 1992, when David Reynard filed suit in Florida against the mobile-phone industry for causing the tumor that killed his wife, American trial lawyers have been dialing for dollars, convinced that mobile phones could be the next tobacco. But unlike tobacco lawsuits, which have cost...
...best results come from combining two or more scanning methods. Some capture the size and shape of brain structures; others freeze-frame the ever shifting activity of nerve cells as they fire and subside. With this information, doctors are beginning to understand--at the level of the neuron--how mental illnesses occur. "Brain imaging," says Dr. Nancy Andreasen, a leading schizophrenia researcher at the University of Iowa and the MIND Institute in Albuquerque, N.M., "has changed the face of psychiatry...
