title: Response latency of vertebrate hair cells.
abstract: 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.
