Electrical coupling between primary hair cells in the statocyst of the squid, Alloteuthis subulata.

Abstract:

:Intracellular recordings were made from primary sensory hair cells located on the dorsal side of the anterior crista segment of the squid statocyst. These hair cells were electrophysiologically identified by the occurrence of an antidromic action potential after electrical stimulation of the crista nerve. Two types of subthreshold, depolarising potentials were observed in the primary sensory hair cells. Firstly, those due to efferent inputs onto the primary hair cells and secondly those correlated one-to-one with action potentials in neighbouring primary hair cells. The former depolarising potentials could be blocked by bath applied cobalt, indicating chemical transmission, while the latter could not. Injection of a depolarising or hyperpolarising current into a primary hair cell depolarised or hyperpolarised, respectively, a neighbouring primary hair cell implying that the hair cells are electrically coupled with an electrical coupling coefficient of up to 0.4.
