Controlling binocular saccades to change fixation in space: a parallel model explanation

Introduces a control scheme of binocular control of eye movements for 3D space exploration. The scheme, based on known anatomy, has been derived following a functional approach; it is able to reproduce many aspects of binocular adaptive control. Binocular control on eye position of the two eyes is achieved by combining an open-loop fast “saccadic” system, operating to produce both common-mode (versional) and differential (vergence) commands, with slow closed-loop system(s) working only in differential mode. The main innovation with respect to previous model proposals is the introduction of vectorial bursters (neural pulse generators), taking advantage from the modulation of the internal activity of the array. The introduction of many burst cells, as it is in nature, lets the model gain adherence to reality and introduces a degree of freedom into the generation of the profiles of the neuronal signals for the ocular plants. This degree a freedom can be used for differentiate the control for the two eyes
