Abstract

A 3D torque-coding neural model of the orbital tissues and three ID tension-coding neural models of the agonist/antagonist pairs of extraocular muscles are needed to adaptively control the motion of the eyes P. Inchingolo Dipartimento di Elettrotecnica, Elettronica ed Informatica, University of Trieste, 34100 Trieste, Italy ABSTRACT A new theory on the control of the oculomotor plants is presented. On the basis of theoretical and experimental studies, we propose that the ocular premotor control neural system generates separately, for each of the six muscles, two composite signals: 1) an eye-driving tonic-sliding innervation, obtained as decomposition in the horizontal, vertical and torsional components of a 3D torque vector command produced by a 3D inverse neural model of the orbital tissues and of the eye ball and 2) a muscle-compensating tonic-phasic innervation, generated by a monodimensial direct neural model of each pair of muscles (including their non-linear tension
