Abstract

Mammalian outer hair cells (OHCs) contain Ca and K channels in their synaptic pole. We questioned if the ontogeny of potassium currents of OHCs depends on the neural induction of early afferent contact. By recording whole-cell currents of OHCs grown in organotypic cultures deprived of afferent innervation, we show that a Ca-activated K channel is expressed in these cells, suggesting that the ontogeny of the K channel is an intrinsic process.
