Mouse Nose Nerve Cells Mature After Birth, Allowing Bonding, Recognition With Mother, Penn Study Finds
For rodent pups, bonding with mom isn’t hard-wired in the womb. It develops over the first few weeks of life, which is achieved by their maturing sense of smell, possibly allowing these mammals a survival advantage by learning to identify mother, siblings, and home.
Blended electrophysiological, biochemical, and behavioral experiments, Minghong Ma, PhD, an associate Professor of Neuroscience at the University of Pennsylvania School of Medicine, led a study published in a recent issue of the Journal of Neuroscience. With students Anderson Lee and Jiwei, she demonstrated that neurons in the noses of mice mature after birth.
