In the experiments reported here, our aim was to determine whether or not the cerebrospinal fluid pressure and the perilymphatic pressure are the same. Several previous investigations explored this question, but simultaneous measurements of the two pressures were not systematically made. It will also be shown how these measurements relate to the circulation of perilymph.

Meurman¹ in 1929 introduced successively 0.5, 0.67, and 1 cc of saline into the cerebromedullar cistern of rabbits. The meniscus in a capillary tube placed in the scala tympani rose 5 mm after each injection. He also noticed movement of the fluid level with respiration. No attempt was made to measure cerebrospinal fluid pressure levels or more accurately correlate the pressures in the two systems.

Kobrak² in 1934 showed that perilymphatic pressure increased after an increase in intracranial pressure. He cemented a glass capillary tube into either the cochlea or a semicircular canal . . . [Full Text PDF of this Article]
