Claim One:
1. A retinotopic command network for choosing a visual point of light for fixation from a field of visual points of light comprising: a photo-detection means having a region for foveating light; a body for supporting the photo-detection means; motors for moving the photo-detection means to a position for foveating light; a choice mechanism for transforming a broad array of lights collected by the photo-detection means into a localized activation of a sector map, wherein the localized activation of the sector map generates spatially coded signals for activating motors which move the photo-detection means to a position which foveates the chosen visual point; a competitive choice means in communication with the photo-detection means and the sector map for converting a broadly distributed input pattern into a more narrowly focussed activity pattern; a means for conditioning the spatially coded signals transmitted to the motors by a conditionable movement circuit which corrects a previous inaccurate movement signal, the conditionable movement circuit comprising: a short term memory means for storing an internal marker indicative of the position of the chosen light on the photo-detection means before moving the photo-detection means; and an error signal generated by the chosen light on the photo-detection means after the photo-detection has moved; and a saccade generator which converts the conditioned spatially coded signals into a temporally coded signal that determines how long, and in what direction the motors will move the photo-detection means towards the chosen light.
