Gap junctions between hair cells and supporting cells in the goldfish saccular macula. A freeze fracture study.

functional asymmetries of myelinated branches in the frog muscle spindle. A study of the permeability of the outer capsule of the frog muscle spindle to potassium ions using ion·sensitive microelectrodes. Introduction Gap junctions have been considered to be responsible for cell-cell communization and are found where electrical coupling or metabolic cooperation is present. 1,2) Many extensive gap junctions have been found between adjacent supporting cells in some acoustico-vestibular sensory receptors. 3) In the present study, gap junctions are found between hair cells and supporting cells in the goldfish saccular macula. The functional significance of these gap junctions is discussed.
