Fig. 4

Post-mortem disappearance of a vibration hotspot. a In vivo vibration map for the 11.2 kHz component of a 65-dB-SPL multi-tone stimulus, showing a clear hotspot in the OHC/Deiters’ cell region. b Post-mortem vibration map at the same frequency, and evoked by the same stimulus in the same cochlea, within 30 min after death. Vibration magnitudes in both panels are expressed in decibels relative to the 2.6-nm maximum observed in vivo at the location marked with the white asterisk in a. The hotspot vibrations reduce at least 10-fold (i.e., 20 dB) post-mortem, while vibrations elsewhere in the body of the organ of Corti increase and BM vibrations remain essentially unchanged.
