Presaccadic spike potential: a computer model based upon motor unit recruitment patterns in the extraocular muscles.
Details are presented of a computer model of the presaccadic 'spike' potential based upon the discharge properties of motor units in the extraocular muscles. The model provides support for the hypothesis that the spike potential represents the summated electrical activity from the near-synchronous recruitment of motor units in the extraocular muscles by the presaccadic burst of motoneurone activity.
