For the first two weeks of life, mice with a hereditary form of deafness have nearly normal neural activity in the auditory system, according to a new study by Johns Hopkins Medicine scientists. Their previous studies indicate that this early auditory activity — before the onset of hearing — provides a kind of training to prepare the brain to process sound when hearing begins.

A new study looking at the brain activity of mice is hoping to shed some light on why some peoples hearing starts to go as they grow older.

In experiments, old mice were less capable than young mice of "turning off" certain actively firing brain cells in the midst of ambient noise.

More research is needed to precisely map the connection between the inability to shut off certain neurons and hearing loss amid ambient sound.

New research in mice, before and just after birth, shows that early exposure to sounds may promote aspects of brain development earlier than expected.
