Caption: A female mouse gathers, grooms and nurses her 3-day-old pups in the research lab of assistant professor of zoology Stephen Gammie. Gammie has studied the link between maternal aggression in mice and levels of a peptide hormone that controls behavior, particularly an animal's response to fear and anxiety.
