Area responsible for self-controlThe results illuminate a very important aspect of the brain's control of behavior, the ability to hold off doing something after you've developed the intention to do it-one might call it 'free won't' as opposed to free will," says Martha Farah, PhD, of the University of Pennsylvania. "It is very important to identify the circuits that enable 'free won't' because of the a number of psychiatric disorders for which self-control problems figure........Go to the Neurology news blog (Added on 9/12/2007 6:39:05 PM)

New Clues to Breast Cancer DevelopmentPhysicians who treat women with the breast cancer susceptibility gene BRCA1 often remove their patients' ovaries to eliminate the source of estrogen they believe fuels cancer growth. Yet they also know that anti-estrogen therapies don't work to treat breast or ovary cancer that might develop. That paradox has led researchers to question exactly how, or if, estrogen is involved in cancer development and whether removal of ovaries makes sense.
