Sustained and transient changes in hydrostatic pressure were transmitted directly to the perilymphatic space of guinea pigs. EP, as well as SP, CM, and AP, was measured before, during, and after pressure changes. Pressure applied to scala vestibuli led to an increase EP and SP, while pressure applied to scala tympani resulted in a decrease of these potentials. Comparable data were also obtained the anoxic cochlea. CM and AP failed to change when moderate amounts of pressure were applied. In guinea pigs whose organ of Corti was largely degenerated EP was normal, but it did not increase when pressure was applied to scala vestibuli, nor did it consistently decrease during pressure applications to scala tympani. These data were interpreted to mean that changes in EP normally occurring response to changes in hydrostatic pressure reflect variations in the output of dc generators located on the basilar membrane.
