(NEW YORK)Researchers at 20 leading medical centers in the US are testing a pacemaker-like device that may ease the symptoms of depression. Cyberonics, Inc., the device manufacturer, is currently awaiting approval form the Food and Drug Administration to begin clinical trials. The implanted device will stimulate a nerve that runs down the side of the neck. The nerve will be stimulated for 30 seconds, stop for 5 minutes, and begin again. Side effects of the stimulation include voice change, a sense that something is in the patient's mouth, and difficulty breathing during vigorous activity. For more information visit www.abcnews.com.
