Caption

A virgin female mouse and a mother mouse are tested on the elevated pup-retrieval maze. As in the example, only mother mice retrieved the pups in this situation (although virgin mice did so willingly in the home cage when it was not dangerous). When the calcitonin receptor was downregulated, mothers also hesitated to take the risk.
