Functional Significance of Visually Triggered Discharges in Eye Movement Related Neurons

Gaze orientation is a quick, natural, almost automatic reaction. Yet, in the couple of hundred milliseconds that separate the appearance of a photic target and the orientation of the gaze to it, the CNS has to make a number of delicate computations and decisions. The where, how, and when of the movement have to be determined. Analysis of single-unit events occurring during this period suggests that the spatial coordinates of the goal are calculated immediately upon stimulus presentation. The information predictive of the trajectory of the orienting movement to be performed appears already available in what, on the basis of fixed latency, would be considered stimulus-locked visual response. The actual launching of the saccade is a separate, subsequent decision.
