Abstract
Increasing cerebrospinal fluid pressure in the cat was shown to cause perilymphatic fluid pressure to increase to approximately equal levels. Obliteration of the cochlear aqueduct completely prevents this response. Decreasing cerebrospinal fluid pressure decreases perilymphatic fluid pressure but to a less predictable extent. The cochlear aqueduct appears to be the pathway of fluid and pressure transmission from the cerebrospinal fluid to the perilymphatic fluid in the cat. The results are interpreted as showing a high degree of dependence of the perilymphatic circulation upon the cerebrospinal fluid circulation.Keywords
