Cochlear summating potentials: composition.
The potential difference across the cochlear partition and the overall potential level of a given cochlear cross section were measured as functions of stimulus parameters and spatial location. It was confirmed that the potential difference is negative in the vicinity of greatest excitation, and it was discovered that in the same region the overall potential level is positive.
