Abstract：
:Static firing frequencies have been determined in extraocular motoneuronal discharge patterns for different eye positions within +/- 30 deg around the primary position. From these data iso-frequency curves were plotted stating all possible eye positions for a given firing rate. Such curves have been constructed for the lateral, medial, and inferior recti, the superior oblique and for the upward pulling muscles (without distinguishing superior rectus and inferior oblique). Fixation of eye position always involved natural synergistic action of all muscles. The iso-frequency curves of individual motoneurons are a family of almost parallel curves with mainly horizontal or vertical gradients. Especially for the superior oblique, the innervation gradients depend strongly on eye position. Motoneurons subserving the same muscle can have different innervation gradients at the same eye position.
