Neuronal distribution of KCNQ4 in several brainstem nuclei. Labeling of several brainstem regions with the KCNQ4 antibody at higher magnification. Multipolar immunoreactive neurons (arrowheads) can be recognized in posteroventral (PVCN) (A) and anteroventral (AVCN) (B) cochlear nuclei. (C and D) Neurons from the lateral superior olive (LSO) and the central nucleus of inferior colliculus (CIC), respectively, with relatively poorly labeled somata but intensely stained neuropil. (E) A section from the eighth nerve just before its entry into the brainstem. Both cochlear root neurons (arrowhead) that are located between axons of the cochlear root (CR) (which is not labeled), and axons of the vestibular root (VR) are labeled. (F) Neurons from the dorsal nucleus of the dorsal raphe (DRD) with intense staining of somata and dendrites.
