Abstract
THE effects of external low-Ca, high-Mg solutions were tested both on frog isolated semicircular canals and on single cells isolated from th ese sensory organs. Our results showed that these media were able to c ancel slow adaptation of the ampullar microphonic current in the whole organ and to abolish a Ca-dependent K current (I-K(Ca)) in single hai r cells, suggesting that I-K(Ca) is involved in vestibular sensory ada ptation.
