survival of efferent synapses on mammalian outer hair cells.

Dr Douglas Vetter (Tufts University School of Medicine) and team recently published a study that amplifies the understanding of the development, function and maintenance of auditory system function.

Their data strongly suggest that hair cell responses induced and/or modulated by Olivocochlear (OC) activation are necessary for the survival of OC innervation and that these responses must involve SK2-mediated hyperpolarization.

It also includes an excellent image of Olivocochlear fibers degeneration in SK2−/− mice. One of the makers used was our Tuj 1 (Neuron-specific class III beta-tubulin).
