Compensation of Vestibular Function and Plasticity of Vestibular Nucleus after Unilateral Cochleostomy

Figure 1

Schematic timeline of the experiments. Auditory brainstem response (ABR) thresholds were obtained before and immediately after surgery, at 10 and 20 days after surgery. The rotatory chair test (sinusoidal harmonic acceleration, SHA) was conducted prior to and at 6 hours and 1, 3, 6, 10, and 20 days after surgery. The assessment of peripheral vestibular organ hair cells was conducted 20 days after surgery. Changes in c-Fos immunoreactivity at the vestibular nucleus were evaluated at 1 and 6 hours and at 1, 3, 6, 10, and 20 days after surgery.
