The effect of membrane electrical activity on spiral ganglion neuron (SGN) neurite growth remains unknown despite its relevance to cochlear implant technology. We demonstrate that membrane depolarization delays the initial formation and inhibits the subsequent extension of cultured SGN neurites. This inhibition depends directly on the level of depolarization with higher levels of depolarization causing retraction of existing neurites. Cultured SGNs express subunits for L-type, N-type, and P/Q ty ...[more]
