title: Identification of prepositus neurons projecting to the oculomotor nucleus in the alert cat.
abstract: A population of prepositus hypoglossi nucleus neurons with discharges correlated to gaze parameters and antidromically activated by stimulation of the ipsilateral oculomotor nucleus has been recorded in the alert cat. The latency for antidromic invasion was of 0.6-0.8 msec. Neuronal firing rate encoded eye position and eye velocity in the horizontal plane, showing in all cases ipsilateral 'on' direction.
