Neuronal activity of the external oculomotor nucleus during saccadic eye movement in the waking cat

Abstract

The activity of antidromically identified abducens nucleus motoneurons and inter-nuclear neurons has been recorded during saccadic eye movements in the alert cat.The activity of these neurons has been demonstrated to be the sum of a velocity component proportional to eye velocity plus a position component proportional to instantaneous eye position during the movement.Results are discussed in relation to proposed models about the generation of saccadic eye movements.
