Brain science offers new understanding of complex emotions

NEWSWEEK has just published this very extensive article on the latest cognitive neuroscience:

Neuroscientists consider it settled that the mind arises from the cooperation of billions of interconnected cells that, individually, are no smarter than amoebae. But it’s a shocking idea to some that the human mind could arise out of such an array of mindlessness. Many express amazement that emotions, pain, sexual feelings or religious belief could be a product of brain function. They are put off by the notion that such rich experiences could be reduced to mechanical or chemical bits. Or they worry that scientific explanations may seduce people into a kind of moral laziness that provides a ready excuse for any human failing: “My brain made me do it.” Our brains indeed do make us do it, but that is nonetheless consistent with meaningful lives and moral choices. Writing for the President’s Council on Bioethics earlier this year, philosopher Daniel Dennett made the point that building knowledge about the biology of mental life may improve our decision making, even our moral decision making. And it could enhance our chances of survival as a species, too.

Your heart, lungs, kidneys and digestive tract keep you alive. But your brain is where you live. The brain is responsible for most of what you care about—language, creativity, imagination, empathy and morality. And it is the repository of all that you feel. The endeavor to discovery the biological basis for these complex human experiences has given rise to a relatively new discipline: cognitive neuroscience. It has recently exploded as a field, thanks, in part, to decades of advances in neuroimaging technology that enable us to see the brain at work. As Dr. Joel Yager, professor of psychiatry at the University of Colorado, has said, “We can now watch the mind boggle!”
