Zonal changes in lobule Xa (nodulus) PKCδ expression during vestibular compensation. The number of PKCδ-immunopositive Purkinje cells per section from every sixth section through the lobule Xa of the nodulus ipsilateral and contralateral to operations is plotted as a function of postoperative time. Separate graphs are shown for the medial nodulus (0–0.5 mm from the midline) and the lateral nodulus (>1.5 mm from the midline). No significant effects were observed in the medial nodulus. In the lateral nodulus, there was a bilaterally symmetric increase in the number of PKC-immunopositive Purkinje cells in both sham and UL groups on the eighth postoperative day (see text).
