The response of the one anterior canal neuron to high-frequency air-conducted sound (ACS), before and after a small dehiscence in the bony wall of the anterior canal. (A) The response of the neuron to pitch angular acceleration identifies the neuron as being an anterior canal afferent. (B) Before semicircular canal dehiscence (SCD), an 8 s burst of 1,483 Hz ACS has no effect on the neural response. (C) After SCD, a 10 s burst of an ACS of 1,479 Hz causes strong activation. Resealing the SCD causes that enhanced response to disappear. Reprinted by permission from Springer Nature, Curthoys (81), © 2017.
