Receptor Potentials from Hair Cells of the Lateral Line

Abstract

Intracellular recordings from hair cells in the tail lateral line of mudpuppy Necturus maculosus show receptor potentials less than 800 microvolts, peak to peak, from stimuli that are considered large compared to natural stimuli. The hair cells are in neuromasts that are sensitive at the time of recording and are identified by both in vivo and in vitro examination of intracellular staining.
