Recorded neurons (n = 249) were classified as phasic (n = 194) or tonic (n = 55) second-order vestibular neurons (2°VN) and were subdivided, according to the presence of monosynaptic inputs after electrical stimulation of particular labyrinthine nerve branche(s). Number of neurons in bold; number in parenthesis indicates percentage of this type with respect to phasic, tonic or all recorded 2°VN, respectively. AC, anterior vertical canal, HC, horizontal canal, LA, lagena, PC, posterior vertical canal, UT, utricle.
