| Method |
Primary source abstract: "Here [investigators] describe electrically evoked mechanical changes in isolated cochlear outer hair cells (OHCs) with characteristics which suggest that direct electrokinetic phenomena are implicated in the response...In the experiments described here, [they] applied sinusoidally modulated electrical potentials across isolated OHCs: this produced oscillatory elongation and shortening of the cells and oscillatory displacements of intracellular organelles." |
| Comments |
P.178 right column bottom paragraph: "Nevertheless, low-frequency changes in OHC length (i.e., up to ∼10 Hz) can be captured by video microscopy (primary source). This technique remains inherently limited by video capture rates (maximally a few tens of frames per second) unless stroboscopic techniques are employed." |
