In two alert cats, single-unit activity of neurons related to vertical eye movement was recorded in and around the interstitial nucleus of Cajal (INC), and their projections to the ipsilateral vestibular nucleus and response to stimulation of the contralateral vestibular nerve were examined. Of 62 neurons that discharged in relation to vertical eye movement, 41 increased their firing rate for downward positions and 21 for upward positions. About one third of downward-on neurons was antidromically activated by stimulation of the ipsilateral vestibular nucleus with thresholds of 36-220 microA. None of the upward-on neurons were antidromically activated. About 60% of INC neurons (22/36) responded orthodromically to stimulation of the contralateral vestibular nerve. In particular, all the downward-on neurons that projected to the ipsilateral vestibular nucleus exhibited orthodromic responses at disynaptic latencies. The results, together with our previous finding that excitatory secondary vestibular neurons carrying vertical position signals project contralaterally to the INC, suggest that downward-on INC neurons receive direct connection from these secondary vestibular neurons and send the signals back to the ipsilateral vestibular nucleus. Interstitio-vestibular interactions through these pathways may be important in the generation of vertical eye position signals.
