Around the spiral of the inner ear of healthy mice, hair cells (green) can detect sounds at different frequencies, from 4.0 kHz (roughly the highest note on an 88-key piano) to 64 kHz (more high-pitched than a dog whistle). (The range for human hearing is much lower: 0.02 kHz to 20 kHz.) Scale bar, 50 micrometers. Credit: X. Gao et al./Nature 2017
