...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...
TODAY'S TREATMENTS Most antidepressants work by tweaking levels of various neurotransmitters, the chemicals that carry signals from one neuron to another. Prozac, Paxil, Zoloft and the other SSRIs slow the absorption of serotonin. Effective antidepressants that act on both serotonin and norepinephrine include Effexor and Remeron. Drugs like Wellbutrin work in a similar way but probably on the neurotransmitters norepinephrine and dopamine. The tricyclic antidepressants (such as Elavil and Tofranil) also blocked the absorption of neurotransmitters, especially norepinephrine, but the drugs had significant side effects. Another class of first-generation drugs, the monoamine oxidase inhibitors (MAOIs) such as Nardil...
...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...
...Poem? Is it the fierce deliberation of one man’s mind that gives it its peculiar flavor, its unmatched intensity, and its startling command of the intellect of the great intellects who devour it? Or is it the beauty of its poetry that seems to penetrate each neuron of the brain...
