AVOR responses during a 2 Hz, 50°/s RALP head rotation of ch050506B encoded by prosthetic stimulation delivered by a monopolar electrode in the LP SCC ampulla with respect to a distant reference. For each panel, stimulus current is labeled; all other parameters were kept constant (fbaseline 100, fpeak 350, C=5, 200 us/phase, cathodic first). In each, the ordinate axis and inverted head velocity trace have been scaled to enhance visibility all components of the response. Barely visible at 50 μA, the response at 100 μA includes conjugate RALP rotations similar to normal chinchilla responses, except for a horizontal component that could indicate horizontal SCC ampulla or otolith nerve stimulation. At 250 μA, the LP response has grown to over 150°/s peak velocity, but the spurious horizontal component nearly equals it.
