Response latency of vertebrate hair cells

Biophys J. 1979 Jun;26(3):499-506. doi: 10.1016/S0006-3495(79)85267-4.


An in vitro preparation of hair cells from the bullfrog sacculus produces a transepithelial microphonic potential in response to well-defined mechanical stimuli. If corrected for the electrical time constant of the epithelium, the response follows a fast stimulus with a 40-microsecond delay at 22 degree C. The short latency and its modest temperature dependence limit possible models for transduction by hair cells.
