How the brain dials up the volume to hear someone in a crowd

Our brains have a remarkable ability to pick out one voice from among many. Now, a team has uncovered the steps that take place in the brain to make this feat possible. Today's discovery helps to solve a long-standing scientific question as to how the brain's listening center can decode and amplify one voice over others. It also stands to spur development of hearing-aid technologies and brain-computer interfaces that more closely resemble the brain.
