Subject: A question on Békésy.
At the bottom of page 475 of his book "Experiments in Hearing",
McGraw-Hill, New York, von Békésy (1960) has written:
"[...] It was further established that the gelatinous mass in the
cochlear duct increased the rigidity of the partition, especially
near the helicotrema. [...]"
What is that "gelatinous mass"? I seem to remember that
the viscosity of endolymph is about equal to that of water.
A wild guess: "gelatinous mass" = tectorial membrane (??)
Your (on- or off-line) suggestions would be very welcome,
of course, even if you are not absolutely sure !
