Voltage-activated currents were present in ORNs from MPS I-affected and control cats. Currents were elicited by voltage steps from −100 mV in 20 mV increments to + 80 mV. Holding potential was −70 mV. A. In an ORN from a control cat, two outward current components (a transient and a sustained current) were observed, as well as a fast transient inward current. B. A recording from an ORN of an MPS I-affected cat showed similar currents with somewhat different time course but comparable amplitudes.
