Saccades (high velocity, conjugate rotations of the eyes) function to bring the image of selected visual targets onto regions of the retina containing a high density of photoreceptors. Recent reviews (Robinson 1981a, Fuchs et al 1985) have documented the progress made in describing the neural signals controlling these rapid, precise movements. These papers considered the literature from the perspective of the motoneuron, emphasizing the generation of command signals by brainstem neurons having relatively direct synaptic connections with the motoneuron pools innervating the extraocular muscles. In this review, we summarize what is known about saccadic command signals found at a more central point-the superior colliculus (SC). Using this information as well as kinematic arguments, we discuss the transformations required to convert collicular signals into those needed by premotor pools of neurons. Also, we consider the functional properties of other brainstem neurons in the context of the required transformations.
