FIG. 7.

Regeneration of the cupula. A Sketch showing observation in one animal of a degenerating cupula displaced toward the utricle and a second regenerated cupula spanning the cross-section of the ampulla. Bode plots showing the gain (B) and the phase (C) of a population of single afferent units in response to sinusoidal angular rotation of the whole animal in comparison to control recordings from a population of normal animals from Boyle and Highstein (1990). Afferent responses did not span the normal range and were biased toward high phase advance (C) and low gain (B).
