Older People's Hearing Troubles May Be Because Their Brains Work With Less Information

Article title: Mutual information analysis of neural representations of speech in noise in the aging midbrain

Authors: Peng Zan, Alessandro Presacco, Samira Anderson, Jonathan Z. Simon

From the authors, "We have provided supporting evidence that the neural response of the midbrain of older listeners is not merely less well synchronized than for younger listeners, but also actually contains less information, in both amplitude and phase."
