Summary
We measured Ca++ activity in the different parts of the endolymphatic space by using a doublebarrelled electrode with calcium liquid ionic exchanger. In the region of the endolymphatic sac, Ca++ activity (4.7×10−4 M) was much higher than in the cochlear duct (2.7×10−5 M) and semicircular canal (2.6×10−4 M). These findings suggest that Ca++ may also have a significant role in abnormal states.
