“…There is evidence that CBF is at least partially under sympathetic nervous system control. Histochemical techniques showing sympathetic fibers surrounding cochlear arteries (25)(26)(27), as well as pharmacological studies applying adrenergic receptor antagonists to these vessels (28,29), suggest that sympathetic innervation regulates the vascular tone of the cochlea. Sympathetic innervation of the cochlear arteries appears to come from the stellate ganglia bilaterally and the superior cervical ganglion ipsilaterally.…”

“…It is well known that the cochlea receives sympathetic innervation [Densert, 1974;Spoendlin, 1981;Pillsbury et al, 1992]. This innervation enters the cochlea together with the cochlear nerve through the modiolus.…”

Potassium (K⁺) plays a very important role in the cochlea. K⁺ is the major cation in endolymph and the charge carrier for sensory transduction and the generation of the endocochlear potential. The importance of K⁺ handling in the cochlea is marked by the discovery of several forms of hereditary deafness that are due to mutations of K⁺ channels. Deafness results from mutations of KCNQ4, a K⁺ channel in the sensory hair cells, as well as from mutations of the gap junction proteins GJB2, GJB3 and GJB6 that may facilitate cell-to-cell movements of K⁺. Deafness results also from mutations of KCNQ1 or KCNE1, subunits of a K⁺ channel that carries K⁺ from strial marginal cells and vestibular dark cells into endolymph. Further, deafness results from mutations of KCNJ10, a K⁺ channel that generates the endocochlear potential in conjunction with the high K⁺ concentration in strial intermediate cells and the low K⁺ concentration in the intrastrial fluid spaces. This review details recent advances in the understanding of K⁺ transport and its regulation in the cochlea and the vestibular labyrinth.
