How Young Mice Phone Home: Study Gives Clue to How Mothers' Brains Screen for Baby Calls
June 15, 2009
Emory University researchers have identified a surprising mechanism in the brains of mother mice that focuses their awareness on the calls of baby mice. Their study found that the high-frequency sounds of mice pups stand out in a mother's auditory cortex by inhibiting the activity of neurons more attuned to lower frequency sounds.
