Figure 2.

HC and TM responses to tone bursts in one cochlea (wub92). Bold and thin lines depict responses under sealed and unsealed conditions, respectively. (a–f) HC responses recorded before the RM was torn to expose the TM. (g–l) TM responses recorded after tearing the RM. Arrows in (d), (i) and (j) point out ‘early onset’ and ‘phase-reversed’ response components observed under unsealed conditions (as described in text). Stimulus level=80 dB SPL. Responses averaged 16×.
