motility

• "This motility is also called 'dancing' because when you electrically stimulate an outer hair cell with a sound, the cell body spontaneously elongates and contracts along with the sound," Zuo said.
• While the knockout experiments were strong evidence for the role of somatic motility, the affected mice also showed structural abnormalities in their outer hair cells, Zuo said, thus complicating the interpretation.
• In the new experiments to more unequivocally establish the role of somatic motility, the researchers genetically altered mice to have only subtle alterations in the prestin protein.
