Consuming alcohol leads to epigenetic changes in brain memory centers

New research revealed a surprising pathway that shows alcohol byproducts travel to the brain to promote addiction memory. They show how acetate travels to the brain's learning system and directly alters proteins the regulate DNA function, impacting how some genes are expressed and ultimately affecting how mice behave when given environmental cues to consume alcohol.

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.
